Port Forwarding in Cisco 1841

Hi Everyone,

I configured my linux server to accept udp port 4669 and 4769. that was easy for me.

That's only a small part of the work.

I got a remote  Cisco Router 1841 ( India )

I need to allow udp port 4669 and 4769 on the router.

traffic passing port 4669 should go to Server0 ( 192.168.XX.XXX) on port 4569 and Traffic passing port 4769 should go to Server1 (192.168.XX.XXX) on port 4569 and should be vice versa. like traffic coming from example server0 using port 4569 should go out on port 4669 to reach my local server.

im completely lost with IP NAT!!

Yogesh,

you need port redirection in this case. In the following sample config, 192.168.10.1 is server 0 & 192.168.10.2 is server 1.

ip nat inside source static udp 192.168.10.1 4569 x.x.x.x 4669

ip nat inside source static udp 192.168.10.2 4569 x.x.x.x 4769

Regards,

Amit
