Hi, We use firewall and VPN togather to connect around 5 remote sites, and never encounter these problems. Make sure that port 10,000 and above mentioned in ur rtp conf files are opened in ur vpn and firewall. also when u connect from remote site don't use public ip use privte behind firewall. If still have problem send me more detail and i will be more then happy to sort this out .
