I have an h6315 working fine.
I can connect to the Cingular GPRS network, surf the net, check e-mails just about everything.
I can even establish a VPN tunnel to my network via the Sonicwall Pocket VPN Client.
So, it appears that I have the WAN stuff configured correctly.
However, I can't figure out what's going on with the Terminal Services Client.
When I start the client, I tell it where I want to connect to (I can connect via a VPN or to a public IP).
When I tell the client to connect, it shuts down the GPRS connection.
I have the same problem if I try and connect using an ICA connection as well.
I've looked around, but can't figure out what setting to change to make this work.
