This is a weird one, so I'll try to explain in as much detail as I can so I'm giving the whole picture.
As I've mentioned in my other questions, I'm in the process of setting up a new Cisco 881 as my WAN router and NAT firewall. I'm facing an issue where NAT NVI rules that I have configured are not…
