SSH Server on a 1720 Router??

In the process of hardening my router and network I've shut down all configuration ports except the serial console. This effectively eliminates my ability to configure my router from the outside. However, is there any way that I can SSH to the router and thereby gain console access to it from the outside?

I'm currently running the following feature set

IP ADSL FW IDS PLUS IPSEC 3DES

verison is 12.3

can this be done or is this a pipe dream?

if not, are there any suggestions that do not require VPN'ing into a machine behind the firewall that's hooked up to the serial console port?

SSH runs over routed protocol, so if you have active interface (Ethernet, Serial etc.) anyone that knows colnsole login/password can access your router (Providing you have not blocked SSH (port 22) in access list, don't have firewall etc.)

Try it by telneting/ssh into the router from one of your networks.
