The link you posted is the one I was referencing. 224.0.0.1 is likely the router address on Sogliphy's network.

Did you install John Welfringer's TCP Mod for the simulator? In this entire thread I did not see a mention of PEP2 vs PEP3. Which one are you using? The simulator program is NOT the same firmware rev as you might load into the Pronto. i.e. Apple != Orange.
