[TriLUG] Re-IP-ing and Firewall

[Warren Weber]

OK, it's late, I've gone stupid and could use some help ...

I am in the process of replacing a server with a SuSE 9.2 system that I built 
connected to my current ISP.  When I bring it up, I will bring it up on a new ISP and, 
therefore, a new IP address.  I changed the IP address and moved the server off my 
handy-dandy KVM (and soon-to-be ex-ISP) and hooked it up to the new ISP using 
spare parts.  Unfortunately, my spare monitor is not smart enough to talk to my 
server once X starts -- but that's not the real problem (I'll move it back to the KVM 
shortly).  Now that I've re-IP'd it, I can only contact it while on the same subnet it 
exists on, not from the "outside".  I assume this is because the firewall needs to be 
told all the rules now apply to a new IP address, but I can't verify this due to lack of 
access to the system.

I'm going to borrow a monitor tomorrow and hook it up, but does this sound 
reasonable?  If so, can someone enlighten me on how to make the firewall work with 
the new IP address ... or at least point me in the right direction in The Fine Manual?

Many thanks!
Warren
