[nsp] Cisco 1720 or above Firewall using DHCP outside

Is it possible to use a 1720 or something in the 2600 range in a dual
Ethernet environment?


Outside is a DHCP DSL router w/ no static IP.


Inside is a static 10.0.0.x network.


The DSL provider doesn't give statics so every time the IP changes I have to
rewrite the config.

Does Cisco make a product (IOS) that takes in a DHCP address and rewrites
the firewall config on the fly to the new address?


I've tried the 12.1 and 12.2 IOS, and haven't been able to get a 12.3 IOS to
try...am I wasting my time?


Thanks for your consideration
