[asterisk-users] ADSL Load Balancing

[Sean Elble]

You can do policy routing on Linux systems too, using iptables' mark functionality, combined with iproute2.  Mark packets patching whatever parameters you wish (i.e.,  in the mangle table in the prerouting chain, match packets on UDP port 5060), and then use ip rule/ip route to route as you desire.  See here for more detailed instructions/examples:

http://linux-ip.net/html/adv-multi-internet.html

Whether this will work well (or at all) for your specific case is questionable at best.  I can't imagine load balancing SIP traffic across two ADSL lines would work well, if at all, but I've never tried it either.  Doing a primary/failover setup would work a lot better, I'd think.

Oh, and my apologies for top-quoting.  Outlook and all...

Hi,

I've got a client with two ADSL connections for redundancy.

Is it possible to set up asterisk to connect to one SIP provider using both adsl connections and load balance between the two connections?
Or to use one connection as the main one, and automatically fail over if the first connection drops?

Or does this kind of thing need a serious network switch?

Thanks
Dan

Hello,

    If you are using Cisco gear (891 SOHO routers for example), take a look at Policy Routing, you can set next-hop routers based on any information available to an access-list.
