Whitelisting IP addresses on ports
I have a PBX at my main office and a remote phone at my home office. My phone at my home office needs to register to the PBX on UDP port 5060 and voice traffic goes over UDP 10,000 - 30,000
If I have a Firewalla in my home office, is there a way I can whitelist my main office's public IP address on ports UDP 5060 and UDP 10000 - 30000 so that the only traffic allowed in on those ports is from my main office?
