CBAC and ISDN DoD

Hello,

on a Cisco 836 CBAC is enabled on the inside Eth0 interface for incomming traffic. If on the outside interface BRI0 for ISP connection used all incomming ip traffic is blocked for returning traffic from initiated inside.

Is CBAC working with dynamic IP ?

Greetings

The CBAC works fine with dynamic IP.

Which version are you using ?

Which is the configuration ?

The fault was, I did not inspect the dialer0 interface out. So there was no dynamic ACLs open for returning traffic.

I inspect the eth0 out which is wrong.

This happens when you are used to checkpoint.

Greetings

Peter
