I would like to use your product as below. I have 5 public IP addresses, one is the gateway assigned to the Satellite Modem
Internet
Satellite Modem (public IP xxx.xxx.xxx.xxx/255.255.255.248)
Zeroshell packet shaping
eth0: 192.168.3.0/24
eth1: public ip
Aserisk PBX running NAT 192.168.3.3
Many other machines in the 3.0 subnet
Asterisk PBX does not like being behind a NAT server so I find it difficult to use Zeroshell as a nat server.
If Zeroshell provided a sip proxy that would be of great help.
The ideal solution would be to run Zeroshell on the Asterisk PBX
What suggestion would you have for this system design?
