My Escient is connected to the same router via a switch. I tried both linksys my wrt610n and the wrt54gs. Yes the escient is on the same network as the pronto. I disabled the firewall in the routers and had no luck that way either. I had not opened the port until I read the post. I entered range 251 to 251 I am not sure what (0xfb) is.

I entered entire script and tried diagnostics log and it was completely empty. Sorry I am sure I did something wrong.
