I am looking into building a Linux based router out of a home-built Linux server. I don't have much experience with the software required however. I would like the server to run the following applications
router firewall kerberos auth server
Optionally, I would like to compliment with an email server.
Can you suggest a good combination of software to fulfill my needs? I would prefer that the router and firewall be web configurable.
As a bonus question. I tripped over ClearOS while googling my way thorough the problem. But I haven't been able to figure out if it is a closed web-configurable router or if it is a fully fledged OS underneath. Does anyone know if you can get access to a terminal and install extra packages on it? I would have to have a need to install some extra component and be unable to because I installed a closed system.
