Hi, I'm going to install freeswitch in a system with LAN redundancy (duplicated). All the pc have double LAN interfaces. How can I configure Freeswitch to work with this configuration? Actually in vars, the variable Domains has this value <X-PRE-PROCESS cmd="set" data="domain=$${local_ip_v4}"/> I have to set one ip of the two network interface? I need to set the sub-net mask? (example domain=192.168.2.101/255.255.255.0) Second question: All the PC with softphone will be connect at two LAN and the two LAN are on different Network. (Example one LAN is on network 192.168.2.0 and the other in the LAN 192.168.1.0). I bind the address of one of the two network to freeswitch. I will add the extension in the internal profile. How does freeswitch understand that an extension is in the local network? All the softphone should stay on the same network, right? What happens if an extension configured in the internal profile, try to contact FS from a different network? Best Regards Alessandro Luppi -- Ing.

The way I do this is to use ethernet bonding in active-backup mode: http://www.kernel.org/doc/Documentation/networking/bonding.txt http://wiki.debian.org/Bonding You get a virtual network interface named bond0 which is assigned your IP. This effectively replaces your eth0. That simplifies the configuration of everything like FreeSWITCH since you then get a single IP to listen on. The bonding driver monitors the slave devices (eth0,eth1,etc) and uses an active one. If a device goes down it automatically switches over to the other. You can also have different profiles on different IPs, with a profile for each device, but if a device fails any calls going to that IP will fail because the signalling/media is still trying to go to that address. Bonding avoids that problem. Bonding will probably be enough for you, but for some extra information my setup is a little more complex than that... that there's redundancy on the network too - 2 network switches each with 100MBit internet feeds from the data centre, and interconnected with a 2Gbit trunk, running RSTP. Each server has one device going to one switch and the other going to the 2nd. It means that if any switch, device, or cable fails the whole thing will find another route (even between switches via the data centre's switch if necessary). A stacked switch would be better, but isn't currently within budget. -Steve On 25 June 2011 10:10, Alessandro <a.luppi@seletech.com> wrote:

Very interesting, I was thinking to something similar.. I thought to create e third virtual interface... So I'll have to use network bonding to all the pc in the network... The two networks will have switch/router (i think hircshmann) so the two networks will be the specular image of the other. In the interface named bond0 will be configured on the same network of the two network interface or I have to create an virtual third network? On the softphone for the server proxy I'll set the address of the interface bond0 of the server freeswitch right? Thanks Alessandro Luppi Il 25/06/2011 12:07, Steven Ayre ha scritto:

bond0 becomes your single network interface. eth0/eth1 aren't used any longer - they're still there but they're just slaves of bond0. That means you get a single IP on bond0 (eth0/eth1 don't have an IP) which is the one FS/softphones would use. If you're planning to have two independant networks with eth0 on one and eth1 on the other that'll cause you problems... it's meant to provide the server with two routes into the same network. Between devices on the LAN it'll be problematic - in active-backup one device will be active and the others disabled. There's no guarantee that all servers'll pick the same slave device though, so some might be on eth0 and others on eth1 which'd mean they wouldn't be able to reach each other. My 2 switches are connected together and use RSTP to avoid routing loops to avoid that, which is why I mentioned it in the 1st email. For the routing to the WAN it'll mean different routers so different IPs, which'll drop calls with NAT on switchover, and force you to listen to both public IPs on bond0 / FS if you're not using NAT which'll also mean dropped calls on switching over. Our network setup is here: http://pastebin.freeswitch.org/16587, how you connect to the WAN really will depend on your ISP/Data Centre though. -Steve On 25 June 2011 11:55, Alessandro <a.luppi@seletech.com> wrote:

Ok, I'll going to talk with who is planning the network to understand exactly the architecture of the network. I understand how to manage two interfaces in a LAN. I think that with router i'm going to work in a WAN. I think also that the two network are connected so the server is reachable from both side and the routing protocol should avoid loops in the network. This is what said to me about network configuration: http://pastebin.freeswitch.org/16588 I've also another question, I'd like also redundancy on FS server (the server machine will be duplicated). I'm going to install 2 server, so if one fails the other is ready to go in service. Have you ever try something similar? I was thinking to an heartbeat daemon to manage this situation...
