cisco 800 series with a dlink router behind

i have a cisco router series 800 (10.10.56.1), it receives the DSL connection to internet, it have attached a wireless router d-link 192.168.0.1, with a Linux-Server 192.168.0.50. I want to redirect port 23(telnet) to 192.168.0.50, but i can?t do it,, when i make a telnet to public internet IP, the cisco (10.10.56.1), answers me... I don?t want this, i want 192.168.0.50 (linux server) answer me... somebody can help me? thanks a lot??

Did you set up the NAT properly for this?

Also, you'll need to let your router know that you're not wanting it to listen on port 23 on the external interface. I believe you do this with an ip telnet source-interface command.

well, i did this: log in the router web interface, Configuration-Forwardin ports... and i put that: port TCP and UDP pointin to 192.168.0.50 (first).. and problem was not solved... in second attempt, i login into the dlink wireless router (192.168.0.1) and redirect port 23 to 192.168.0.50, in this same attempt, i say the cisco forward port 23 (telnet) to 192.168.0.1.. but problem persists... sorry if the question is a lot basic, i don't have experience with cisco routers...

I don't know how to do it in SDM, but on a command line, you'd just put in:

ip nat inside source static tcp (dlinkrouterwanip) 23 interface (waninterface) 23

You need to forward off port 23 to the DLink router. . .then from the DLink, forward it off to the server.

Hi,

Create a static NAT entry in the router with in-side config.IN statifc NAT give the IP other than any of our interface IP (like 10.10.56.2) and NAT to linux server IP address. This should solve your problem.
