I would like to use your product as below. I have 5 public IP addresses, one is the gateway assigned to the Satellite Modem
Satellite Modem (public IP xxx.xxx.xxx.xxx/255.255.255.248)
Zeroshell packet shaping
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?
I think you could use a Virtual Server configuration to forward the traffic to the PBX.
From the section [Router]->[Virtual Server] you can create the port forwardings. In any case, I don’t know how many and what ports you have to forward to make your PBX to work.
