[asterisk-users] load balance with 2 wan connections

[Sebastian]

Hi,

One possibility that you might want to explore is OpenVPN. If your VoIP 
clients support OpenVPN (either through a local Openvpn client on the 
clients network being used as an OpenVPN gateway, or through individual 
clients supporting OpenVPN (laptops with softphones, or I've heard of 
one particular hardphone supporting OpenVPN - but can't remember which).

Once you are using OpenVPN - it is a bit easier to setup a failover 
scenario - or even load-balancing - as Openvpn has some inbuit 
functionality in this direction. There has been some recent discussion 
on the OpenVPN list about load balancing and failover setups if I 
remember correctly.

Just a thought,

Sebastian
