We have a Sonicwall TZ170 that we are using as our firewall and we are using the global vpn client with it for our remote user. Our UC520 is a node on the Sonicwall Lan and our remote users can ping the uc520 tftp server at 10.1.1.1 but their ip communicator is not registering. When we bring the same laptop on our internal network, the ip communicator will register correctly. What are we doing wrong?
Using UC520 Software Pack 8.2.
