I'm in need of a wireless router than can have OpenVPN installed on it, so connecting devices such as ipad, kindle fire etc will have vpn access. After a little research I understand that I need a router which supports openwrt. I've found a list of such routers.
However what are the minimum ram, cpu requirements to run OpenVPN on a router? I've only ever installed it directly on client machines. I see many routers, openwrt compatible, which have 64Gb of ram and 400MHz cpu speed. Is that sufficient?
From my limited knowledge, OpenVPN doesn't require a ton of ram, but CPU is important. Thanks for all advice!
