It may be that simple. It depends how ipchains is configured on your
machine.
I had an ipchains script that would get the external ip address and stor it
in $EXTIP when ever I ran the script so if I did happen to change my
external ip I wouldn't have to change the files assosiated with the
firewall...your config may be entirely different though.
But I dont see why you cant just update linux and all firewall assosiated
files with the new ip, as long as you update everything other wise you'll
have problems...of course.

Subject: [SLUG] Ipchains Firewall
We have an ipchains firewall that has multiple IP addresses set up on the
external NIC. We are going to change to a different ISP and will require to
change the external IP addresses. I just want to check that this is as
simple as just changing the IP addresses in linux and changing the ip's the
ipchains config files.
Thanks
Andy
