i am not sure if this is possible or not because i am somewhat of a novice regarding this router but here goes....

i am using a third part VPN (PureVPN) which in itself works great but the problem i am having is that i 2 pc's that are gaming pc's and i am getting rather high ping rates from the VPN so was wondering if i can somehow just have the VPN active on say 2 ip's within my LAN

is this possible if so how?
oh and the router is a dratek vigour 2760

can anyone help on this because i contacted draytek but the response they gave is very vague and i can not make sense of it
