htcom Posted December 22, 2012 Report Share Posted December 22, 2012 I'm after a bit of help here please. I am setting-up a debian SnomOne system for a customer who has two broadband circuits. One circuit is for his general lan - web, email etc. The second circuit is exclusively for VoIP. The debian server running snomone has two NIC's. eth0 is set as static 192.168.10.10 for his Lan connectivity and eth1 is set as a dhcp client connected to the voip broadband router(it gets a dynamic public ip - no nat here). The problem I'm seeing is that the sip trunk on the snomone is routing through eth0, whereas I really want it to route through eth1. I have had a look at the SnomOne IP Routing List option, but can't see how to specify a routing list where the public ip is dynamic. I suspect this may be a linux routing issue , but I'm not familiar with ip routing on Linux. If any could advise I'd be grateful. Thank you Quote Link to comment Share on other sites More sharing options...
Vodia PBX Posted December 22, 2012 Report Share Posted December 22, 2012 What is the output of "route"? Also, what Linux distribution are you using? Quote Link to comment Share on other sites More sharing options...
htcom Posted December 22, 2012 Author Report Share Posted December 22, 2012 What is the output of "route"? Also, what Linux distribution are you using? Thank you for replying snom ONE. The Linux distribution is Debian Squeeze. The SnomOne version is 5.0.3 (CentOS32) The output from route is: Destination Gateway Genmask Flags Metric Ref Use Iface 10.0.0.2 * 255.255.255.255 UH 0 0 0 tun0 lo0-central10.p * 255.255.255.255 UH 0 0 0 eth1 localnet * 255.255.255.0 U 0 0 0 eth0 10.0.0.0 10.0.0.2 255.255.255.0 UG 0 0 0 tun0 default lo0-central10.p 0.0.0.0 UG 0 0 0 eth1 default 192.168.7.1 0.0.0.0 UG 0 0 0 eth0 Quote Link to comment Share on other sites More sharing options...
Vodia PBX Posted December 22, 2012 Report Share Posted December 22, 2012 Not being the biggest Debian expert, I would think that you have set a default gateway on your static IP, which is probably not a good idea. http://wiki.debian.org/NetworkConfiguration I would have the dhclient assign the default gateway, which seems to be the default. Next time, please use route -n; this is easier to read... Quote Link to comment Share on other sites More sharing options...

You are absolutely correct, when I remove the default gateway entry from the LAN statically assigned nic then the sip trunk uses the 'correct' nic connected to the voip broadand router. Another thing that seems to fix the issue is to set a metric value to each of the nics. Using ifmetrics and setting the wan nic card to have a lower metric value than the lan nic also seems to work. Every thing now seems to work as expected and thank you for your help on this snom ONE. Quote Link to comment Share on other sites More sharing options...
