Any idea how to solve this? try use 2 different subnet addresses instead of both addresses on the same subnet. e.g. 192.168.1.101/24 192.168.2.101/24 and also use ip command to add the address to the interface instead of ifconfig and eth0:x notation. that way the OS will pick the correct address when responding to in coming packets. the problem is when you assign 2 addresses to the same interface on the same subnet, one of them will be primary and the other will becomes secondary on that subnet. the OS will always pick the primary address when sending out packets on that subnet. -- Edwin Lam edwin@officegeneral.com Systems Engineer, OfficeWyze, Inc.

Re: [asterisk-users] Binding asterisk to two static IPs
Hi Dale, Wow, thanks for the tip. I just start to change the network config, and see how it works. If your networking equipment supports VLAN, you could add a virtual lan to the existing ethernet device. Jeah, got a Cisco managed switch. Then assign an address to eth0.42. You can use eth0 for your endpoints and eth0.42 for your provider or whichever way you want it. Don't you think the problem will still occur that the answers from asterisk seem to come from the main address assigned to the NIC? Or isn't this possible because of the vlan?

Don't you think the problem will still occur that the answers from asterisk seem to come from the main address assigned to the NIC? Or isn't this possible because of the vlan? Thanks, Georg It should work. As far as the OS and routing tables are concerned, eth0 and eth0.42 are different network devices on different subnets. If the 2 nic solution would work for your problem, then this should work just as well. By creating the VLAN, you are effectively working with a 3 nic solution.

Re: [asterisk-users] Binding asterisk to two static IPs
When you set bindaddr=0.0.0.0 Asterisk will not bind to any specific IP and the OS will choose the source IP of the packet.Let me repeat this: THE OS PICKS THE SOURCE IP. If your OS routing tables are correct, then the packets will be sourced from the correct IP. -Original Message- From: asterisk-users-boun...@lists.digium.com [mailto:asterisk-users-boun...@lists.digium.com] On Behalf Of Dale Noll Sent: Thursday, October 13, 2011 12:47 PM To: Asterisk Users Mailing List - Non-Commercial Discussion Subject: Re: [asterisk-users] Binding asterisk to two static IPs On 10/13/2011 10:53 AM, ge...@riseup.net wrote: Just tested this, doesn't work.

This has two different subnets for eth0 and eth1. Do you have different IP subnets for eth0 and eth0.42? If you do, I do not know the reason for the problem. Ah, sorry, overlooked this. I will give it another try with different subnets. Thanks, Georg -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?

Yes: Use bindaddr=192.168.1.102. That's how we solved it on our Asterisk boxes. Another solution would be to use tcp, but not all SIP clients support that (and I don't know how good Asterisk does). Personally, I think this is a shortcoming in Asterisk. Every application with udp server functionality should handle this correctly. E.g. FreeRADIUS has a compile time option for this (--with-udpfromto, unfortunately off by default, for whatever reasons). -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?

Re: [asterisk-users] Binding asterisk to two static IPs
i had a similar challenge having Asterisk listen to multiple ports.. some of my agents located in countries where SIP is blocked the only effective way is to use IPTABLES i believe your problem can be solved with the same method.

However, there was never a reply to this thread. I'm using a HA-cluster to run asterisk, on two servers, with two virtual ips. One for the phones to register, the other one from a different net to send and receive calls trough my provider. This is aswell a private net, without nat. From [1]: If you put 0.0.0.0, it will bind to all addresses. In a HA Cluster, on the active node, if you have a box address of 192.168.1.101 and a floating address of 192.168.1.102, then if you use bindaddr=0.0.0.0 you will find that phones on the 192.168.1.x subnet will not register on the floating address, which of course defeats the point of HA clustering.
