Hello All, This could be more a routing/linux problem, but I'm wondering if can be handled somehow within *. I have a client that has a contract with a VoIP provider. This contract limits number of phones registered using same IP to 3. There are 3 ways to handle this: 1. Few ATA connected to 3 phones + network 2. Linux router that lies between * box and network. Virual interfaces, iptables SNAT/DNAT ..... 3. * properly configured connected to the network. I looked for * configs, but I did not find a way to send traffic for phone1-phone3 as Public_IP_1, phone4-phone6 as Public_IP_2 ...and so on. Anyone ever did something like this using just a box? Any ideas are welcomed. Thank you, Bogdan
