SSH Pass-through AND SSH To Router

Hi,

I've a question regarding SSH on my router. Right now I have things set up to do pass-through to a server I have on the inside of my network. However, I'd also like to be able to SSH to the router itself but it seems like after setting up pass-through I can't do that anymore. I'm sure there's a simple solution, like configuring a new interface but I'm not sure I understand what that solution is.

Any advice? Config below.

Thanks!

Jon

I believe you can change your ssh port on the router like:

ip ssh port rotary 1

That might work.

HTH,

John

HTH, John *** Please rate all useful posts ***

Mmmm....didn't do anything here. Not sure if this clarifies things or not but I need to be able to do the following:

1. ssh directly to router.

2. ssh directly to server (via passthrough).

Wondering if I need to use PAT here?

TIA,

Jon

Or, do I configure a separate interface to ssh to the server and use the original interface to connect to the router?
