You don't need gated; that's an implementation of a routing daemon (which includes a number of routing protocols); if your network is simple you can probably stick with RIP (i.e. run routed) or static routes (some people don't like RIP over slow speed serial lines, but the overhead on 14.4Kbs lines is really very small...) What you DO need is to recompile your kernel with the options GATEWAY options IPFORWARDING (I'm not sure if you need the latter; at one point you did and I've left it in my kernel configs ever since...) statements. Check out the FAQ for how to rebuild and install a new kernel. Once you have the new kernel, you must assign IP addresses to the serial and ethernet interfaces so that they are in different subnets - for example, if you are routing between class C network 192.1.1.0 and 192.1.2.0 you might assign the ethernet interface 192.1.1.1 and the serial interface 192.1.2.1. Also you'll probably need to define a default route (if your're running routed, and your provider is using RIP, you will probably get a default route automatically); for example route add default 192.1.2.1 would make the serial interface (your gateway to the world...) the default way to send packets out (if there's no default route then the system won't know what to do with "foreign" packets...) You'll probably also want to set the default routes on your ethernet connected machines to point to the ethernet on the FreeBSD box so that they'll know how to get to the world too...
