I'm having the hardest time trying to come up with the correct way to support my configuration. Surely I'm not the only one in this boat...

The network I've got Trixbox Pro SE deployed on is secured behind Microsoft ISA 2004 (MS Small Business Server 2003). This has worked fine until now, as all Trixbox has been used for is with POTS analog lines. Now of course, the client wants to move to VOIP. And it is no secret that ISA 2004 hates SIP. So I thought a simple solution would be to put a consumer DLINK router in front of ISA, stick a second NIC in trixbox - and the tricky part - configure trixbox pro to use the second NIC to access the internet (and SIP) , and the original NIC to communicate with the Aastra IP phones, and connect the second NIC on the Trixbox pro machine to the consumer DLINK router. Everything was going great until it came to configuring trixbox pro with the multiple NIC setup. How do I do this? I don't mind getting my hands into the command line so long as I've got some clear directions...

This might be a good place to point out that this is a VERY small setup. 3 Aastra phones, and two ananlog extensions (total 5 phones for those in the audience keeping score).

If this setup is impossible in Trixbox Pro, what are my alternatives? Use an AIX? Remove ISA (please no, I just got it setup perfectly...), VLANS, QoS, layer 3 switches, and a whole bunch of stuff the client can't afford?

From what I read, this seems possible in the Trixbox Appliance (it has multiple NICs, right?)

Any help is appreciated!

how about putting the router on the existing LAN and setting gateway to it on the pbx? leave one NIC on the pbx. everything else can hit ISA like they do now.

Would that bypass all the ISA SIP issues? What about the Aastra IP Phones? Which side of the consumer DLINK router (placed as suggested by IcelandDreams) would they go on?

Yes, it will work.

You can have many gateways out to the internet on the same subnet.

Example

Gateway 1 (ISA Server)
192.168.1.1
All users have this Gateway
configured as default gateway

Gateway 2 (DLink)
192.168.1.254
Configure Trixbox using
this as the default gateway

What else would need to be done?
Fri, 10/09/2009 - 2:09pm

Hi,

Sorry for resurrecting an old thread, but I started looking into this type of set up to move our IAX connection to a separate internet connection (cable connection, Linksys WRT54G router running dd-WRT, different subnet) and away from the rest of our network (low speed DSL where any internet traffic effectively kills IAX call quality to the point of unintelligibility).

What should I be considering in making such a change? Would this work? Are there any guides that I haven't been able to find that might describe how to implement this?

Any help would be appreciated.

- Henry

Regarding the ISA Server

I don’t know if here is the place where I should put this comment, anyway please help maxwellb, I am trying to install a trixbox Pro behind a Microsoft ISA Server, I just don’t know how the ISA server must be configured nor how trixbox Pro would be configured. I really really appreciate help.

ISA Server is simply a bad firewall. Fonality STRONGLY recommends against this firewall due to the confusion in getting it configured correctly. I can't be of any help here because I have never tried configuring ISA for trixbox Pro myself, but I do know that others have done it successfully...although not without a lot of headaches.
