Basically, I needed to bridge my ethernet and wifi LAN using Mac OS X. Possible solutions: Use an Airport Express. Easy (simply configure the ethernet port with a static IP and disable all other features to have it bridge ethernet/wifi traffic), but not that cheap. Use IPNetRouterX. It looked easy to use, but I didn't really like the idea of.

Am I missing something with this hint? Isn't this what the 'Internet Sharing' feature (System Preferences->Sharing->Internet tab) is for?

Internet sharing only allows one direction access.
This allows communication in 2 directions.
Machine A -- Router -- (Internet and Machine B)
This setup allows machine A to talk to Machine B, and Machine B to talk to Machine A.
Internet sharing would only allow Machine A to talk to Machine B.
Unfortunately, you need to know the IP address of the target machine.. but otherwise this works well.

Not true.
This is exactly what Internet Sharing does. Its simply a router so communication is possible in both directions. I have the very same setup here in my house and it works like a charme.

Let's get Rob to change the title of this hint to 'One unnecessarily complicated method of bridging network interfaces.'

You have just set up your mac to be a router, NOT a bridge. A bridge operates at layer 2, not layer 3.
If you had set up a bridge, you would have created a virtual bridge interface and added both network adapters to it. The bridge interface would get a single IP address, and then anything connected to either interface could have an address from the same range, and would use the address of the bridge interface as their default gateway.
This way, broadcasts and multicast packets (such as the Redezvous protocol) would be able to be seen by all machines on both interfaces. In addition, a bridge will participate in Spanning Tree if you have multiple switches in your environment. A common use of bridging on hosts is configuring redundant interfaces to connect to multiple switches, in case a switch or a network link goes down.
Bridging is an actual networking term, and what you have set up has nothing to do with bridging.

Doesn't Rob check these hints before publishing them? Or does Mac OS X need a knowledgeable technical editor to filter out the non-hints? As has already been pointed out, there is already a one-click solution built into the Sharing panel of the System Preferences.

You have over-complicated your network, and as a result you are proposing adding even more complications :-)
You have 2 routers, with 2 separate but probably colliding address spaces.
What you need to do is disable router functionality on one of the boxes (either wired or wireless), and slave the second box to the first - or replace your wireless router with a dumb access point.
Actually, since wireless routers probably have a few wired ports as well, you can get away without a second router altogether. If you run out of wired ports, get a hub or a switch.
This way you have a single address space, all of your devices can see each other, etc. And, you have fewer devices to maintain.
The only caveat is security. If you don't use authentication on your wireless network, you should consider it 'hostile' because you never know who comes to steal your traffic. So lock up your wireless access - and you should be fine.

While I'm happy to have a hints website, some of them seriously need more quality control before they are posted. I am pretty sure this is a long and unnesessary way to network, albeit usually a way your typical PC WEENIE would do most things (my appologies to the original poster, I just couldn't resist taking that little jab at you). I'm childish. Anyhow, if there is anyone out there that is an absolute networking professional please let me know, I have a complex setup and would like to compare notes. In short I have multiple internet lines, one dsl and the other cable. So if anyone is up for it post here let me know. -digitol-

Most people seems to have missed the point of what I was trying to achieve.
To simplify:
Computer A is on my LAN.
Computer B is on my LAN and has internet access.
Computer C is on the Internet.
Computer B has Internet Sharing enabled.
So now, computer A and B can both reach computer C. Yay!
But I also need computer C to be able to reach computer A on my private LAN.
To be able to do that, computer C needs to know where is computer A, so I forced a route (config. on computer C) to computer A that goes through computer B. And I configured computer B to route incoming connections for computer A to the LAN.
Anyone who has a better way to configure computer B to allow access to computer A from the Internet is welcome to reply to this comment.
From what I found though Google searches, there's no way to configure the default Mac OS X Internet Sharing to do port forwarding, or DMZ.
- Guillaume

I read two drastically different descriptions of your setup and goals; but if I just listen to the example in this reply-thread, I don't understand why you don't just port-forward inbound ('from the Internet'; Computer C) traffic to Computer B via your router's undoubted ability to accept port forward commands to a single subnet IP address (like a DMZ, but is still port restrictive).
For example, I have a wired and a wireless LAN both at my workplace.
The wireless LAN is top-level; i.e., it hosts all the standard client/guest computers, printers, etc., and can accept guest access either wired or wirelessly; it also uplinks to the Internet (via cable modem). It is, of course, firewalled, but less-restrictive, to allow more communication in/out and across the LAN. Ffile transfers and freedom of movement/access is critical to workflow, and risk is dealt with by safe practice, virus software, etc. It is vulnerable, and frequently attacked, but no critical or sensitive data lives for long at this level. This is superfluous to our conversation, but is here to explain why *I* need two LAN types, and why I don't just use a wired/wireless combo LAN (as cheap as $15) as others have suggested you just convert to.
The wired-only LAN is at the second level, using its own firewall and router, so that I can protect my sales stations and sensitive data, customer data (credit card info, sensitive files, etc.); it uplinks to the level one LAN.
The computers on the second level need to be able to see/use/access the printers and computers on the first level, and can easily do so by passing IP-specific requests up through the second-level router to the first-level router; as well as access the Internet, which just get passed normally from gateway to gateway. Requests in the other direction are summarily denied, except for the following:
I frequently need to access my primary workstation under the second level from either a computer on the first level, or via the Internet from home. Similarly, our web server also resides behind the firewall and router at level two.
In order to access these computers/services 'from the Internet', I have the first level router set to port-forward, e.g., port 80 requests (HTTP) to the second-level router, and the second level router points those same requests to the web server IP address. The same is true for file access; AFS ports are forwarded to my workstation, as are VNC and SSH port requests. These, of course, are further protected by 128bit passwords and secure sockets.
Any need to access any other computer on the second level is passed through my station as host. This is the 'bridge' to which you refer and seek.
While you have created a situation that works for you, and was free, but, for most people, a $15-$50 all-in-one wireless/wired router combo, which has built-in bridging (i.e., wired and wireless computers receive/can specify IP addresses in the same range and subnet mask) is the best solution, as it also unifies all behind a single firewall. You point out the ultra-cool AirPort as too expensive for your taste, but if you watch the specials, you can get D-Link, Lynksys, or lesser known but just as good brands (like Hawking), that also have printer ports for enabling 'network' printers without resorting to printer sharing via a host, for as little as free, if you watch rebates and such.
e.g., this deal is common, and ones for less that are new with more featurres and with free shipping come along all the time:

Most wireless routers have a built-in Ethernet switch, so none of this should be necessary. I'm using a Linksys WRT54G with my servers & iMac connected to the ethernet ports and I connect to it wirelessly from my MacBook Pro & Mac Mini.

@gboudrea:
There is a MUCH easier way to do this. Just about any router nowdays will achieve what you need. Furthermore, if you need you can configure multiple ethernet interfaces in your network pane. Multihoming is what I think you may be after.

Well, folks complained about this hint at the time, but four years later, I wanted to do exactly what gboudrea was trying to explain, and his explanation was the only really sufficient one on the internet.
I'm now able to use my Mac Mini to act as a 5ghz radio to serve my TiVo hi-def video via ethernet, without having to buy a separate $80 box. And gboudrea correctly explains how I can connect into the TiVo from within my LAN.
Hours and dollars saved. Thank you.

With bridged networking, Oracle VM VirtualBox uses a device driver on your host system that filters data from your physical network adapter. This driver is therefore called a net filter driver. This enables Oracle VM VirtualBox to intercept data from the physical network and inject data into it, effectively creating a new network interface in software. When a guest is using such a new software interface, it looks to the host system as though the guest were physically connected to the interface using a network cable. The host can send data to the guest through that interface and receive data from it. This means that you can set up routing or bridging between the guest and the rest of your network.

Even though TAP interfaces are no longer necessary on Linux for bridged networking, you can still use TAP interfaces for certain advanced setups, since you can connect a VM to any host interface.

To enable bridged networking, open the Settings dialog of a virtual machine, go to the Network page and select Bridged Network in the drop-down list for the Attached To field. Select a host interface from the list at the bottom of the page, which contains the physical network interfaces of your systems. On a typical MacBook, for example, this will allow you to select between en1: AirPort, which is the wireless interface, and en0: Ethernet, which represents the interface with a network cable.

Bridging to a wireless interface is done differently from bridging to a wired interface, because most wireless adapters do not support promiscuous mode. All traffic has to use the MAC address of the host's wireless adapter, and therefore Oracle VM VirtualBox needs to replace the source MAC address in the Ethernet header of an outgoing packet to make sure the reply will be sent to the host interface. When Oracle VM VirtualBox sees an incoming packet with a destination IP address that belongs to one of the virtual machine adapters it replaces the destination MAC address in the Ethernet header with the VM adapter's MAC address and passes it on. Oracle VM VirtualBox examines ARP and DHCP packets in order to learn the IP addresses of virtual machines.

Depending on your host operating system, the following limitations apply:

• Mac OS X hosts. Functionality is limited when using AirPort, the Mac's wireless networking system, for bridged networking. Currently, Oracle VM VirtualBox supports only IPv4 and IPv6 over AirPort. For other protocols, such as IPX, you must choose a wired interface.

• Linux hosts. Functionality is limited when using wireless interfaces for bridged networking. Currently, Oracle VM VirtualBox supports only IPv4 and IPv6 over wireless. For other protocols, such as IPX, you must choose a wired interface.

  Also, setting the MTU to less than 1500 bytes on wired interfaces provided by the sky2 driver on the Marvell Yukon II EC Ultra Ethernet NIC is known to cause packet losses under certain conditions.

  Some adapters strip VLAN tags in hardware. This does not allow you to use VLAN trunking between VM and the external network with pre-2.6.27 Linux kernels, or with host operating systems other than Linux.

• Oracle Solaris hosts. There is no support for using wireless interfaces. Filtering guest traffic using IPFilter is also not completely supported due to technical restrictions of the Oracle Solaris networking subsystem. These issues may be addressed in later releases of Oracle Solaris 11.

  On Oracle Solaris 11 hosts build 159 and above, it is possible to use Oracle Solaris Crossbow Virtual Network Interfaces (VNICs) directly with Oracle VM VirtualBox without any additional configuration other than each VNIC must be exclusive for every guest network interface.

  When using VLAN interfaces with Oracle VM VirtualBox, they must be named according to the PPA-hack naming scheme, such as e1000g513001. Otherwise, the guest may receive packets in an unexpected format.
