Routing problem with 1 remote IP with NAT

[ppicard]

I just upgraded from a CISCO2514 to a Cisco 2611XM for my internet router.

Everything is working fine except 1 remote host (FTP server) that I cannot connect to.

If I telnet to that server from the router itself, I am fine, but not from remote hosts behind the router

From the Router:

gw#telnet xx.xx.97.14 2000

Trying xx.xx.97.14, 2000 ... Open

220 xxxxxxxx (glFTPd 2.01 Linux+TLS) ready.

From a telnet prompt on a pc:

patrick@desktop:~$ telnet xx.xx.97.14 2000

Trying xx.xx.97.14...

Connected to xx.xx.97.14.

Escape character is '^]'.

< message from remote server never appearing >

If i place my 2514 back in place ...i am fine..

Any ideas on what would be causing the issue? I attached the config's of both routers

try to make ur nat looks like

ip nat inside source static tcp 192.168.2.3 20 interface FastEthernet0/1 20

ip nat inside source static tcp 192.168.2.3 21 interface FastEthernet0/1 21

then reload the router then try it

if worked then the problem with maped ports

good luck

the issue is not others trying to access my FTP server.

It is me trying to access a specific remote FTP server running on port 2000.

As part of my troubleshooting, i try to telnet to the remote server on port 2000 from a PC behind my NAT...no success

Then I try to telnet to the remote server on port 2000 from the router itself==success

it is only a problem with this specific remote host.
