Are you trying to connect to a computer that's connect to the internet with wildblue excede? or are you trying to connect to a computer some where else while your connect to the internet with wildeblue excede?
Ether way, have you considered an altertive solution? For instance LogMeIn?
My Mac is the Admin computer, it is a MacBook Pro running Mountain Lion, connected by ethernet to a cable modem. The client computer is a MacBook running Lion, and it is connected to a DSL modem by ethernet. I know about logmein, but want to try Apple first. I may have to go that route.
My struggle now is establishing port forwarding on the Time Capsule. I have not found documentation on how to do this in Mountain Lion.
