Hi Guys

Looking for some thoughts and any information or links.

I would like the be able to bond multiple WAN connections over vpn tunnels. The reason for the tunnels is i want to be able to give the end user static public IP from our pool in the data centre. I have got standard bonded/load balcing working well not a issue, but i can not see how i can give the customer a public from our pool and bond the traffic across 2x wan or 4xwan

We have a 1Gb www connection in our data rack we are running CCR36 in the rack, this dose our edge routing etc.

Has anyone done such a thing and is it possible? I have a couple of service that use a kenton kbr 1645 this bonds ADSL and VDSL connections and give one or multiple public IP's but the solution is not the cheapest.

I can think of a couple of options...
1. you set up multiple L2 tunnels through VPN transport (either EoIP through GRE/IPsec/SSTP/whatever, or use PPP with BCP) and add a bonding interface to those tunnels
2. you simply use multiple tunnels with dedicated transport networks each and use ECMP routes (which isn't real bonding, but really working nicely)

Or, as you correctly stated, the smartest solution would be the kenton kbr - or a SilverPeak SDwan appliance (and I'm sure there are even more comparable appliances on the market).

Depends on the bonding mode you want to use, but generally it is not recommended to use bonding over VPNs. Bonding in most cases requires equal link speeds which is hard to get over the internet and even more vpn over the internet.
