SSH to outside interface of a PIX 506e

ride_1976 · ‎03-29-2007

Hello, I can't seem to get this working. I would like SSH to work on the outside interface of my PIX 506e. When I use PUTTY to connect, right away it says "server unexpectedly closed the connection." Here is a copy of the config:

generate the activation key again by this command:

(config)#ca gen rsa key 1024

also,

if you initialting the request from ,let's say 1.1.1.1 on outside,then please add the follwoing command :

ssh 1.1.1.1 255.255.255.255 outside

just replace 1.1.1.1 with ur ip address,put in the ssh command,generate the activation keys once and that should take care of this.

That worked! Thanks for your help. How would I get telnet working to that same outside interface?

suschoud · ‎03-29-2007

telnet does n't work on the outside interface because of the security concerns.you can enable it on inside/dmz though.

telnet 192.168.1.5 255.255.255.255 inside
