Our normal method for firewalling PBXs is:

1. Locate the PBX behind your primary NAT firewall
2. Permit all outbound traffic
   • Only because it's easy
3. Permit no inbound traffic
   • Other than the next items
4. Forward voice traffic in to the PBX
   • Destination NAT (DNAT)
   • All forwarded port ranges are UDP
   • 5060-5061 for SIP and SIPS
   • 10000-20000 for RTP
5. Limit the port forwarding rules by source-address-list
   • Create an address list
   • Add all Vitelity IP addresses
   • Add fixed IP addresses of any remote extensions
   • Only forward the ports if the traffic comes from trusted partners
6. Make sure that forwarded traffic is permitted
   • Mikrotik RouterOS devices do this automatically with the forwarding rules
