Hi All, I faced an issue today where i created a new ACL on Cisco Router zone based firewall. The ACL didn't work as i wasn't seeing any hit count on that, however i was able to see that the source ip was being natted whilerouter, firewall, security going out. I added the ACL in another Class-map and it worked fine. router, firewall, security Now i want to know the exact packet flow in cisco router when configured as a firewall, as what i know from ASA the policy will be inspected at first then the NAT would be applied. If my ACL was not sequentially correct then how come the source was getting NATted? Please explain the packet flow here.
