Re: [asterisk-users] How to have Asterisk respond from the IP address used for registration
Hi Andrew, I tried that (ref.: http://www.tipsternet.com/articles/advance%20routing.htm) but althought my packets do seem to be marked (when I used -J LOG with iptables I do see the appropriate packets being logged) but when Asterisk sends back the response, the mark seems either to be gone or ignored. I am no routing expert, but coming out of Asterisk the responses back aren't marked are they? I mean, strictly speaking those aren't the same packets as the ones that came in.

The reason why I am not using a diff server per provider is that for some customers, half the phone will be on provider A and half on provider B (home-based personnel). They still keep hints and stuf to work as if they were on the same server. So my original question I believe is still valid, even if the IPs used as exemple made little common sense (as you`ve rightly noted) This isn't really an Asterisk issue, it's network/routing - however ... Two solutions I can think of. The first is the easiest is to get a separate router with three network interfaces - one goes to your LAN with the asterisk server, the other 2 to the 2 ISPs - the router then does all that's needed to keep the streams separate, or does load balancing, or whatever. There are many makes and some even run Linux. The other way is to have 2 NICs on the Asterisk box, each connected to one of the 2 ISPs, then you need some routing magic on the Linux box to keep the streams separate - this example: http://lartc.org/howto/lartc.rpdb.multiple-links.html builds a Linux router, but it should work with applications running on the router (which is jus a Linux box) itself.

Hi Andrew, Thanks, I'll look this up. The term packet mangling wasn't used in my many google searches. Mike On 28/05/2010, Mike l...@virtutel.ca wrote: That was a simplified example.
