Re: Determine IP Address of Router

[Vernon Hamberg <vhamberg@xxxxxxxxxxxxxxx>]

+1 to this - I used to use a router inside my cable modem at home - that 
gave me an internal address that never changed. Now, because of port 
forwarding issues, it was simpler just to set up my DSL modem as the 
internal router - and I use dyndns.org - and I've never been unable to 
connect from outside. Well worth setting it up - and simple dyndns.org 
is free - they have for-cost services, as well, IIRC.
