Asus RT-AC66U using OpenVPN with TAP

mkhatib

I hope I am in the right place to ask this question.

I have an Asus RT-AC66U router running the latest firmware. I am trying to setup the router with OpenVPN to allow remote user with laptops outside the office to connect as if they were in the office on the inside network. It's my understanding to do that I need to use TAP (Bridged mode) so they are on the same subnet.

When I use TUN it's easy everything works at least I get the IP address etc.. on the client side (laptop running Windows 7 Pro), but I can't access anything on the network which makes sense since they are on different subnet, however when I try to use TAP the router for some reason does not push (I do have DHCP enabled) the IP addresses to the client. I even tried to add the IP address on the client but still it doesn't see the network.

I can't find anywhere on the net any example how to use TAP with Asus routers. I don't want to use the PPTP because it's not secure anymore. I even went into advanced mode on the Asus VPN page and made changes there and exported every time I made changes the config file for OpenVPN.

If you need any additional info i.e. config file etc... please let me know and I will post it here. Please any help would be greatly appreciated or at least point me in the right direction.

Also, I noticed that most examples are on using TUN compared to TAP and I understand the reason but how do people connect to there network remotely and still have access to their network when they are on separate subnet? I know with Cisco they use split tunnel is that what people are doing with they use TUN on Asus, Netgear etc...

Thanks.

Can you post any config file from your router with respect to OpenVPN ?

Also, any log file generated by OpenVPN may help ...

Hi Thanks for your reply.

I finally got it to work with TUN. I also found out from ASUS there is a bug in the firmware for TAP and they claim there should be an update in a couple of weeks, I will believe it when I see it. But for now everything is working great.

Thank you so much for trying to help.
