Hi, I'm new here, and I hope that I'm in the right place.
I have three separate gigabit LAN's that I want to interconnect over the internet via Openvpn in bridge mode.
Lan 1: 200 Mbit/s down 20 Mbit/s up;
Lan 2: 200 Mbit/s down 20 Mbit/s up;
Lan 3: 200 Mbit/s down 200 Mbit/s up;
Now I'm trying to find out which VPN routers I should get to do this, without them becomming a bottelneck. Where can I find VPN routers that come with OpenVPN installed or can be installed with OpenVPN.
I was first looking at the Linksys LRT-214 and 224 before I found out about OpenVPN. And I found out that these have a maximum IPsec throughput of 110Mbit/s. So I might be reading this wrong, but I believe that this means that they would form a bottelneck uplouding from let's say LAN 3 to LAN 1 or LAN 2. I believe that OpenVPN doesn't work with IPsec, so the question is what would the right througput be to interconnect al these networks and what VPN router can do this with Open VPN.
Second thing is that I also have a spare Asus RT-AC68U with the stock firmware. If possible I'd like to use it as one of the VPN routers in bridge mode.
Q2: what firmware could/should I use (tomato/merlin/DD-wrt) to do this, and do they all have the option of OpenVPN in bridge mode.
Q3: what is the maximum throughput of a OpenVPN bridge running that firmware.
Can Anyone help me?

First, you do not need router based OpenVPN to achieve your goal you can simply use OpenVPN on a machine in each of your networks. Preferably Linux.
Second, you can look for OpenWRT or pfSense routers but we cannot possibly provide a list of all such devices. Maybe some of the Forum members would like to share their findings .. ?
Last, for the purpose of making your mind up try using a OpenWRT(x86) and pfSense(x86) which are both free to download and use in a virtual machine on a pc and decide which you prefer ..

Traffic, thanks for your answer.
Yes I know that I can use a machine on my network. That's one of the things that I'm trying to figure out.
I believe that I will need a dedicated machine if I'm going to use pfSense. And in any other case, I don't have spare machines on the network to run a virtual router on. So I would have to build a new machine to run it or buy a VPN router that works with pfSense or another system.
Then the question pops up, what throughput (and if I have to build it myself, what hardware) would I need to bridge these three networks using OpenVPN, without the routers forming a bottelneck.
And another question that jus came to mind, what extra processingpower would I need for the encryption. Somebody told me that I would need one core per VPN connection. But what kind of core? A core on a Intel core with hyperthreading (so a quad core I5 with hyperthreading has 8 cores?
And I would still like to know if it's possible to use the Asus RT-AC68U as one of the routers and if so, can this be done with merlin, or would I need DD-WRT?
By the way, please excuse my spelling. English isn't my native language.
