I am trying to setup a Linux box behind a Cisco router that has NAT turned on. I configured:
ip nat inside source static udp 10.10.100.20 53 xx.xx.xx.xx 53 extendable ip nat inside source static tcp 10.10.100.20 53 xx.xx.xx.xx 53 extendable If I do dig . @xx.xx.xx.xx From the internet, I get the proper response. tcpdump on linux shows the packet arriving and a response packet. If I do dig domain.com @xx.xx.xx.xx I get no response. tcpdump on the linux box shows a reply packet leaving it and the router responding with ICMP host unreachable. Software is IOS (tm) C1700 Software (C1700-K9O3SY7-M), Version 12.3(18), RELEASE SOFTWARE (fc3) Any ideas are welcome.
