Multihoming VPN endpoint

2008-03-25 Thread Curo Technology Support
Hello List,

I have a question regarding setting up a VPN on a multihomed WAN link,
we are thinking about setting up a site with two load balanced ADSL
links that includes a site to site VPN.

Does anyone have any experience in this kind of setup that could offer
up any advice?

Regards

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.

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.


Regards,

Steve
