Hi,

I intend to apply static NAT to highlighted servers on the KLRTR router but the issue is the interface s0/0/0 has no IP address as it has sub-interface (S0/0/0.203) of frame relay on it. While the pinging from DHCP server works but the NAT does not, as no translations shows up in sh ip nat translations

So I applied the NAT on the sub-interface on S0/0/0.203 but then the sub-interface s000.203 already has an IP assigned to it so it didnt work as NAT translations work but the sender doesn't get a ping response. In simulation mode mode the packets fail at KL_ISP, not sure why even though I have static route set on KL_ISP to enter the network and other devices are able to ping.

If I ping from Internet Web Server to DHCP server on its inside local IP, the ping is successful but fails on pinging on the outside global IP

I applied IP address to S0/0/0 and then I applied NAT on it which I tried but it didnt work.

I need to know how to solve this issue.

Thank You
