VPN and loadbalancing will not be possible however you can get redundancy with the VPN. If you configure one ADSL connection as primary default gateway and the other as secondary (with higher AD) it should be acheivable. Ofcourse we'll have to do a li'l more brainstorming in order to get it work.


Please rate if it helps,

Can I do it by another way (I heared about different Cisco technology like DMVPN or GETVPN) can theses technologies do the multilink and how, or I have to change my routers or IOS versions or it is impossible to do it with cisco devices
