Here you go Brian.

Your IP: (which you already provided) : 45.62.248.66
Is IP static: YES
Hostname: (only really matters with dynamic IP): N/A
Source Interface: f0/1 (FastEthernet0/1)
Writable SNMP Community name: foobar

For reference, here is the currently running Tunnel12 to Tim's A12RTR:

Tunnel12 is up, line protocol is up
