Rob, you should describe in more detail your load balancer/firewall.

If it is possible, you should use your firewall to NAT the approriate ports for 
the "PUBLIC" ip address sipxbridge is asserting.

(5060, 30000-31000 UDP). You should also allow those ports outbound. Ifyour 
ITSP allows it, you should send signalling "out" port 5080, andthey should send 
signalling back on 5060.

What links you use probably wouldn't matter if your firewall can handlethe 
public IP address PAT/NAT and this way your 3 uplinks wouldn'tmatter.

If my assumptions are correct (they may not be, but do correct me if Iam 
wrong), then your configuration questions/issues center around 
yourfirewall/load balancer.

Thanks for your response. 

My experience with sipx is that it binds only to one ip address, eth0 for some 
reason. 

The sipx box would run a firewall, iptables configured to only let through the 
sip traffic. 

There are two reasons why this seems desirable: 1) we can dedicate a specific 
high quality internet connection to the sip trunk (back 2 back user agent, 
right?) and 2) we're using load-balanced, bonded Ethernet connections (3 of 
them) through our main firewall, which means that the ip address may and does 
change based upon load and changing ip addresses tend to cause problems at the 
ITSP or sipx.

Would you recommend other ways of doing this?

Assuming a private and public address? o, it will not work. Two nic's is not 
supported yet and there is no way to bind specific services to a specific 
interface. Sipx binds to all.

Describing what you are trying to achieve might prove more input.

It is NOT a good ide to put sipx outside without a firewall with a public ip 
address.

Subject: [sipx-users] Possible Deployment Scenario

Hi.

Is it possible to deploy sipXecs with a network
configuration<http://rob.contractpal.com/>where sipXecs has both a
public IP address and a public IP address. Only the
Trunking Service would be connected through the public IP address.

Thanks!
Rob
