[CentOS] Do I need a dedicated firewall?

I used to run everything in a similar manner, behind an IPCop system.

The UVerse gateway doesn't handle multiple IPs on the same interface, when
plugged directly into the gateway, so I wound up ditching the IPCop system
and using my server as both the server and a firewall/router as you're
asking about.

You should be able to do so with no trouble.
