TOPIC: Problem with NAT

Problem with NAT 10 years 4 months ago #28429

I have a 2600 router and i want to achive a goal of mapping a public ip to a private ip in the LAN so telnet & ssh can be accessible from outside the domain.

ip nat inside source static tcp 23 23

i can ping the public ip and get a reply

SL-R2651#sh ip nat translations
Pro Inside global Inside local Outside local Outside global

tcp --- ---

But the problem is i cant get telnet nor ssh to connect from outside the domain.

Your ip nat statement seems OK (for telnet). You will need to also add one for SSH (port 22).

[code:1]ip nat inside source static tcp 22 22[/code:1]

You need to also specify which interfaces on your 2600 are inside or outside, for example:

[code:1]interface FastEthernet0/0
ip address
ip nat inside
interface FastEthernet0/1
ip address
ip nat inside
interface Serial0/0
ip address
ip nat outside[/code:1]

If it still doesn't work after checking the above, then could you post a debug ip nat output for us ?
