Hi Syed, If Paltalk is like any other voice/video app, there's a good chance it requires secondary connections. That will require the Firewall client or an application filter for the SecureNAT clients. You'll need to know the precise primary and secondary connections, and maybe tweak the mspclnt.ini file.
