[Solved] Windscribe Wireguard VPN

[egc]

@Louis0115

• By turning on the Route Allowed IPs, traffic through WAN also gets cut off when I disable the VPN connection, is that expected?
• What is the difference between using this feature vs implementing a kill switch by removing wan from "Allow forward to destination zones" of lan firewall config?
• Ultimately, I want to set up the VPN so that a few devices (TV, and some media devices) can be routed through VPN whereas the majority of the devices should stay on standard WAN traffic. Occasionally, I might want my phone to switch to VPN from WAN network, Would using PBR be the best solution for it?

When you disable the VPN connection the route is still in place, you need to restart the network (service network restart) to reinstate the default route via the WAN.
This is not a "kill switch" a kill switch is like you described i.e. removing FORWARD from lan to wan. But this is not compatible with your next question for which PBR is the solution: https://docs.openwrt.melmac.net/pbr/

About MTU your normal WAN MTU is 1500 and WireGuard has 80 bytes overhead (if IPv6 is used) so 1420 is the max (for PPPoE where the WAN is 1492 you use 1412).
Sometimes this is even too much and if you have slow/hanging connections especially when using streaming media you have to lower it below 1420 (1412)

Glad it is working.
