I purchased this router specifically for its OpenVPN feature, but when I tried to set it up, I realized that the router doesn't actually have a VPN feature. I upgraded to the beta firmware, but it only offers weak encryption VPNs, which is not what I need. It would be greatly appreciated if you could provide another beta firmware that includes the features I require. I hope you can solve this issue for us. Thank you. 

P.S. Please ensure that you follow through with what you promised in the specifications.
