I am finally ready to buy a VPN service. I am using a Dell Optiplex 755 (with XP Pro), and a Mikrotik RB750gr3 router. This router has crappy support for OpenVPN, so IPSec protocol is likely required. I would want to tie the VPN into the router. Hopefully one with a GUI client, and firewall/killswitch. As for cost, I definitely do not want to exceed $100 a year, and would rather it be much less. So any recommendations for VPNs that work with XP Pro, use IPSec, has a GUI, firewall to prevent leaks, and not too expensive? I realize that is a tall order.
