I cannot get the equivalent of "Internet Sharing" to work right using Snow Leopard server. What I would like to do is have the Snow Leopard Server share its en0 with the fw0 interface -- or more accurately bridge the two network interfaces such that traffic can pass both ways. The ethernet interface is the primary interface used in my Server set up, and is plugged into my Time Capsule, and serves out both DHCP and DNS for any clients connected wirelessly or through one of the time capsule's remaining ethernet ports (behind and not exposed to the WAN). The firewire interface is just connected to a mac mini in hopes of having a low latency network connection that I plan to use for some multiprocessing experiments. Things work almost correctly in that the fw0 client machine on subnet 192.168.2.* can talk to all the clients on the 192.168.1.* en0 subnet and vice versa. However, DNS is not successfully being served to the fw0 client. Furthermore, things like ``ping'' are not traversing the network en0/fw0 successfully, suggesting that the interfaces are not correctly bridged. I took a look at the Gateway Configuration Assistant, but that feature appears to make too many bad assumptions, does much in the way of user controls, and clobbers already established parameters that I had set up. I tried it once, and it made a royal mess of various settings. It just seems that if this is a 1-click step in OS X, it shouldn't be so hard to do in Snow Leopard Server. Even under linux it's just a matter of an ifconfig command with bridge related command line options to achieve this. Can anyone suggest what I might be missing or perhaps point me to the script that is behind the Gateway Configuration Assistant? Maybe I could parse that script to suss out the missing step that I need to take. Thanks.
