TCP/IP Over Radio - Application Setup in Clients

Generally, you should not need to modify any settings in your TCP/IP applications (browser, email program, etc) if you have configured the Windows' IP ROUTE, HOSTS and ARP tables correctly and have successfully run a PING test to the distant station. 

If you experienced problems with an application not using the correct network, i.e. radio network vs internet, look for a solution in the entries in your Windows IP ROUTE, HOSTS and ARP tables.

For example, if you are trying to communicate with a mail server on the radio network, make sure that the email account setting in your email program either specifies the mail server's IP address (beginning with 44) or that there is an entry in the HOSTS table that translates the server's name, e.g. mail.SV2AGW.net, to an IP address, e.g. 44.0.0.6.

For all IP packets with addresses beginning with 44, Windows should send them to the SV2AGW TOR adapter. If if doesn't do that (no outgoing packets in PE Pro's monitor), then add a route in the IP ROUTE table linking the mail server's IP address, e.g. 44.0.0.6, with the SV2AGW TOR adapter, e.g. 44.0.0.2.

And finally make sure there is an ARP table entry that links the server's IP address, e.g. 44.0.0.6, with the server's correct packet callsign, e.g. SV2AGW-8. Without that entry, Windows will send a packet to "QST" asking for the station with that IP address to report back with its callsign.
