Question : Multiple Remote Site VPN - Low Bandwidth

Hi,

I am wondering if anyone would know a solution to the VPN dilemma I have.

We have 6 remote offices and one main office. The main office has the Servers and 3 of the remote offices connect to a terminal server at the main office using an IPSEC VPN and also use VOIP h.323 between each other using an LG Aria system. I would like to connect all of the remote offices to the main office but the problem is that it has limited bandwidth options because of it's semi-remote location. ADSL2 (getting 800k upload) is the quickest we can get without paying some ridiculous amount per month.

At the moment I am using a SnapGear SG580 at the main office with Dual ADSL2 connections one for web/email traffic and one for the VPN for the largest remote site. We then have an SG560 with one ADSL2 connection for the other 2 remote sites. We then have an SG560 with an ADSL2 connection for the VOIP.

At all 3 remote sites we have SG560's with Dual ADSL2 Connections, one for VPN one for VOIP.

I have a few problems with this setup:

1. It is a spiderweb and it's growing, I would rather have everything consolidated rather than having so many devices at the main office.
2. The SnapGear's don't have integrated ADSL modems, I have brindged ADSL modems to the Firewalls which I find to be unreliable. I have to reset modems and the SnapGear probably once every week or two at one of the locations.
3. If I add 3 more sites it will be a nightmare at the main office.

Does anyone have any suggestions without spending a bucket load or am I in utopia thinking this is possible using ADSL2.

Thanks for any help,

Jason

Answer : Multiple Remote Site VPN - Low Bandwidth

Then i would approach your ISP there and see if they have a solution were you could get multiple dsl lines coming in and pipe then into "The Magic Box" and out the other side comes a bigger pipe, similar to load balancing a newtwork, i have done it with satilites where we took 3 of then and chained them together. So i think asking your ISP for some help would be the next step.
