I think you meant the VPN server. You should consider the DIR-330, and this device provides up to 8 VPN configurations. (VPN server: PPTP and IPSEC tunnel.)
But DLiink Doesnt have a product that does both.
QOS, Wireless G, and VPN.
QOS is more important to me so i choose that. But having a router which does all 3 would make alot of sense.
