Fortigate 600D, FW 6.2.2 build 1010, Windows 10, using latest Forticlient, 6.2.2 0877, and have determined no FW is involved.
I have clients on SSL VPN that cannot communicate between each other, just like probably everyone else higher up this thread.
I've tried addind a policy from ssl.root to ssl.root, SSL VPN range to SSL VPN range, all services. Still no communication. All those clients can communicate with the remote networks fine. For example CIPCs (Cisco softphones) can place calls and receive them from people not connected to the SSL VPN.
I've also reduced my Client IP range from .1-.254 to .4-.254, as .1-.3 seemed to be problematic for connectivity from the remote network.
When a call between Forticlients is attempted, signaling works, as in the phone rings, but when taken off-hook, the line opens, but no sound on the line.
I'm at a loss right now. Anybody would have suggestions?
