Since my ISP restricts some incoming connections, I can't access remotely to my home pc.

What I'm trying to do is make a reverse ssh connection from my home's router with Tomato firmware to the office computer, so I can access remotely from the office with that open connection.

What I'm doing is running the following from the router:

ssh -R 12345:localhost:22 oUser@office

Then I leave run top open to keep the connection alive.

And from my office what I do is run the following:

ssh hUser@localhost -p 12345

but I get the following message with verbose on:

OpenSSH_5.5p1 Debian-6, OpenSSL 0.9.8o 01 Jun 2010

ssh_exchange_identification: Connection closed by remote host

I've password remote access enabled in Tomato's configuration, so I should be able to access without having the public key on *authorized_keys*, but I've even tried adding it and still the same.

I've done the same with my home's computer, and it does work perfectly, but it doesn't with the router.

Am I doing something wrong?

Thanks in advance.
