Change in config on 1700 when firewall is introduced - HELP!

Posts: n/a
Hi everyone,

we have a 1721 which was serving as a router/firewall up until now on an
ADSL line.

We recently purchased a Watchguard 700 firewall to sit next to it. I assume
that the IOS config needs to be altered as follows:

- remove access lists controlling incoming traffic
- remove NAT statements

Now the firewall is configured with a Public IP in the same range as the
Cisco but I cannot see how the Cisco will know to trust those queries and
route them successfully through the Dialer interface.

Any help will be appreciated.
