GS Wave only working on LOCAL WIFI


I’m having trouble to setting up the Grandstream Wave App. on my iphone 7 with sonic wall SSL VPN.

But its working perfectly on Local Wifi without VPN. when Im trying to connect with SSL VPN its not working.
but i can able to login grandstream UCM 6208 web page when i connected to vpn.
i already forwarded tcp/udp port 5060 and rtp 10000 - 10100 on my soicwall TZ300.

please help to resolve this.
