In the next month I'm going to be changing our T1 provider. I'm
BM3.0EE. Two NIC, one public, one private. Static and Dynamic NAT,
Proxy, FTP Proxy, DNS Proxy.

Here are the steps I've come up with off the top of my head.

Changing the filters to refer to the new Public IP's.
inetcfg binding setup.
Proxy settings to refer to the new public IP's.
The hosts file and startup files for the static NAT's

Did I forget anything or is it not this easy.
