Will this multi-home setup be co-ordinated with a single ISP? The problem with this setup is that most ISP's can not guarantee which LNS your ADSL will connect to, ingress traffic may not be load-balanced, or may not work at all. > Does anyone have any experience in this kind of setup that could offer > up any advice? Yes, but we need a few questions answered first. - one or more ISP's (are you looking for ISP redundancy) - will this particular site be the VPN end point for the other sites (and do you have other ingress traffic to this site, ie web server, email server etc) - is your ISP(s) co-operative when it comes to changing their network to suit it's clients - does your ISP(s) support multi-link (aka bonded, aka bundled) ADSL links - are you looking strictly for load-balancing, or do you want redundancy too If you don't get too far here, you may want to migrate the thread over to -net.
