I posted this in another forum but thought it would better fit here. I've got a Cisco 1721 that I've configured to allow external SSH connections into the router from the Internet on port 2922(then translated to port 22).
For some reason, the SSH connection randomly gets dropped, most of the time in the middle of typing a command. I don't think it's related to the length of time because I could not type anything (or type very little) and stay connected for a while. Once I start typing a bunch of commands, it will soon disconnect me. If I try doing a "show tech" I'll immediatly get disconnected (even after connecting 5 seconds before). If I try from the LAN side, it works fine. Would this have something to do with the firewall or IDS?
I already tried "crypto key zeroize rsa" to regen my public key but that didn't help.
Any kind of help would be appreciated.
