I have a Watchguard x750e in the office that I am trying to establish a hardware based VPN with. Pretty straightforward. Herein lies the problem: I am looking for a non Watchguard appliance to do this with. Since setting up VPNs through different manufacturers can be kind of tricky I was wondering if anyone here has any first hand experience setting something like this up. So basically I'm looking for a recommendation, something as inexpensive as possible. The cheapest appliance from Watchguard is like 300-400 dollar range. I'm looking to go with an older type/model of something that I could snag off of eBay. I will need about 4 of these appliances and the budget is rather tight.
The ultimate goal here is the need to get a Panasonic VoIP telephone working from outside the office. I hope that is enough info. What do you guys think?
