linksys ddwrt to astaro vpn?

hey all,

I have been using astaro for a while and now my sales guys want to connect multiple devices in the ssl vpn back to my office.

They have been using ssl vpn but now they just want a router/black box to carry that they plug into client sites or hotel and be able to vpn to the office without having to login on their computer individually?

can I use linksys ddwrt?
