Subject: External IPs on an Internal Box
Sender: owner-freebsd-questions@FreeBSD.ORG

Here's another question for you guys:

At work we have a T1 plugged into a FreeBSD gateway which in turn goes into a 24port Intel Switch which then goes into a patch panel. The T1 has about 16 IPs given to us, but only one is being used (by the Gateway).. all the boxes are using internal IPs (192.168.1.xxx).. my question is this: Is it possible to give one of these internal boxes an external IP? Plugging a switch/hub before the T1 goes into the gateway is not an option...

the configuration is like this:

T1 --> FreeBSD GW ---> 24 Port Switch ----> 22 boxes

We want some (not all) of those boxes to have external ips but still go throught the gateway.. 

Is this possible? And if so, how?

TIA,

        RSN
