Let me start by saying I am not a network guy. I barely know enough to be dangerous. That said, I will install some equipment on a small private network with only a level 3 switch passing multicast traffic from 3 desks to a "server PC" which will then send unicast traffic to some equipment and vise versa. This will be installed far away (4 time zones) and I need to gain access to the "server PC" via VPN connection for maintenance. When I research VPN routers I see some reviews where they might start out good and stable but after some time (days) they require to be power cycled. I really need something reliable and secure. Any suggestions from you battle hardened network guys?
