Configuring VPN on Linksys E4200-V2 (Marvell Chipset)

[Absydion 0]

I've looked at some guides regarding configuring a VPN through the router (so that my external devices like my console, etc. can all work through the VPN), but they mostly recommend running DD-WRT, and this router of mine is incompatible with CFW due to its Marvell chipset. 

 

Is there any way to configure AirVPN through the default Linksys Firmware?
