Does anyone know if you can setup ssh to allow tunneling through a router. Does the ssh app within IOS allow port forwarding itself? Similar to a bsd or Linux OS? Or is this a security feature (by not allowing port forwarding)
I want to make sure that this cannot happen on any of my edge routers! I'm running a K9 image and use ssh for admin and want to make sure that it cannot be configured to forward ssh ports inside the network.
I wanted to make sure that no one could use a cisco router via ssh tunnels on the router to create a secure tunnel through the router. I have found that you can't so that fixes my security issue. The only why someone would be able too is by modifying the configuration and i would get alarms from my monitoring and MARS system that someone changed the configuration.
