I am looking at setting up a VPN, speed it a big factor. I am looking at SSL VPN or Open VPN (not supported by many routers). Putting security aside which do you recommend? For instance, the Barracuda X200 has SSL VPN only most of the Cisco routers do not support OpenVPN also.
I'm open to other protocols also please let me know what you think is the best VPN for EU to US connections.
If site to site VPN you need an appliance that can handle the amount of traffic that will pass between sites
If client access you need one that will handle the most concurrent user sessions you can imagine
You can install OpenWRT on a variety of SOHO routers but if you are doing site to site and have more than 10 people per location I would avoid this
For larger implementations you should look at the firewalls offered by; Meraki, SonicWALL, FortiNet, Cisco, NetGear, etc
My choice would be Meraki but you want to have the same device type at each end.
Remember though no matter what brand you go with you will likely need to license multiple remote access clients to get everything working.
If you give me an idea of size, traffic expectations, and connection types I can advise specific models.
