I am trying to replace old ISA server by Zero Shell 3.8.2.
I have created one interface for internal network with static IP address 192.168.0.250/24 on eth0 and four subinterfaces with different VlanID at eth1 (192.168.6.1/24 at ett1.500, 192.168.7.1/24 eth1.502, 192.168.8.1/24 eth1.503 and ppp connection on eth1.530 for ISP). Internet and routing of big number of services is working OK but when i’m trying to call by SIP phone between networks – I can listen a person from other side but he can’t listen to me.
I have thought about NAT betwen this subnets but in the NAT interfeces I have selected only ppp0.
What do i change in the ZeroShell config for correcting this trouble?
