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,
