[Asterisk-Users] VPN's

[Shamsul Arefin]

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 .
