Best router for heavy load PPTP VPN between my two offices?
I have 2 offices in 1Gb fiber and I need to connect them through PPTP or OPEN VPN. I am currently using 2 Asus GT-AX11000. These work ok, however they max out on the VPN at about 250 Mbps and they crash and need power cycles every few days.
The primary function is that I need ALL traffic from site b to be routed through site A. Therefore I also really need something that allows me to not allow non-vpn traffic out. The asus when the vpn goes down defaults to internet and sends everything out that way.
Any suggestions? Sorry for formatting issues, on my phone driving down a bumpy mountain road (I’m riding)
Two Ubiquiti UDM Pro’s would work well for this.
I would not recommend PPTP as a VPN, as it’s old and not encrypted. There are many routers that have builtin OpenVPN or IPSec. My Asus router (RT-AC86U) has them as well as PPTP, and I use OpenVPN.
SRX 300’s with IPsec
they crash and need power cycles every few days.
Just as an aside, are you aware that you can schedule a reboot of these routers every day at whatever time you like? It may help you in the short term until you find a replacement.
I will look into those
Yes open vpn is fine, but that router can’t handle our traffic load. 
I believe pptp is no longer used by them but they offer other offerings for vpn setups.
The RT-AX86U (not the RT-AX86S) supports 2.5 Gbps WAN. I would think that should suffice. This is the new WiFi 6 version of the RT-AC86U (my router). I just haven’t felt the need to upgrade yet.
Yes it’s fine for internet traffic, it shits itself and cries to mommy when your open vpn gets over about 80mbps. We’ve tried.
Don’t run the VPN on the router then. Use a different device.
I have all my individual users (and there were a ton working from homes all through 2020/21) run the clients on Windows, Android, and Macs (Tunnelblick). I’ve never bothered running it from router to router, although I’m aware you can.
On the Windows client, you can have it startup automatically and just connect.
Also, for router to router, you could try IPSec and see if that solves your throughput problems.
