We have a Cisco 671 router in front of our server. The server is connected to a VPN with Bell. All incoming communications from remote clients arrive on port 8888 and all passes through correctly. All outgoing communications to the clients are through port 6666 and nothing is reaching any of the clients. All communications are UDP. Outside the VPN all works correctly. Any suggestions or ideas on how to correct this problem?
