How do I access my Tomato SSH connection with Putty from an external network?
My home network now looks like this: Internet <-> Belkin modem/router <-> Asus router (Tomato SSH) <-> Devices
- SSH set up on the Tomato firmware on an Asus RT-N10, via port 22 with key authentication.
- Keys tested by connecting with Putty directly to the router when connected to its WAN. That works OK.
- This router is behind a Belkin (F5D7632-4) router, which also acts as modem, and when I try to connect through via SSH with the (dynamic) public IP it times out
- Is it something to do with the Belkin NAT?
- Putty is set up for port 22, with the correct key as mentioned
- The Belkin router has port forwarding to the Asus (192.168.2.3) for port 22 TCP and UDP set up
How now do I connect to the Asus router with an external IP - if it's even possible?
Ideally I would have liked to have only needed to use the Asus router, but as it doesn't act as a modem, I need to connect it to the Belkin in the first place.
All help appreciated,
