Does IOS support SSH TCP port forwarding ?

Thank you,

I think yes Cisco IOS support SSH and TCP port forwarding.The following document explains u how to enable Secure Shell on Cisco IOS routerd and switches.I think this would help you clearly.

I don't think so... it would really be a stupid move of Cisco to allow this... however I could see the use for it.. :)

As the 12.4 IOS Security Configuration guide says:

"Secure Shell - Restrictions - Execution shell is the only application supported."

Did it help?

Hi,

If you mean fordward a request on a internet router1, port 22, to a private router2/gw ,port 22, using nat, try this:

ip nat inside source static tcp 22 22 extendable

This command has several issues. First you need to specify the address of router2 somewhere. Second the first port listed shouldn’t be 22, because that would conflict with SSH (if it’s enabled) on router1.
