two ip can't login

Hello:
i have two network cards in a vicidialnow
eth0 = 192.168.10.12 (private)
eth1 = 200.56.232.18 (static public)
inmediatly after login, give me: 'your session has been disabled'
i don't know how configure the sip.conf to work like this or where is the problem.
The goal is skip the firewall (pfsense) becuse behind the nat give me many problems.
