@th1950 Not taking away from the fact that they should consider this option to fix/add the feature, could you not achieve the same effect now while you wait via a work around something like:

  @th1950 The two subnet rules I gave you are essentially equivalent to the 0.0.0.0/0 route.

  @th1950 

by default settings, won't do that. and I don't think it is supposed to do that. if you achieve this, this is more than a thing about the tplink. you need to specify the gateway and create routing tables on the hq central site as well.

at least what I learned about vpn, I checked huawei business solutions for a similar setup or user guide for what you described. amazon vpn as well.

https://docs.aws.amazon.com/vpn/latest/s2svpn/VPNRoutingTypes.html

what I see is static routing on amazon's or huawei's docs.

however, you need to take priority into consideration. as far as I know, tplink router will have priority in nat related settings. policy, port forward, static route or vpn route, they have a priority. 

instead of tweaking remote subnets, you need to focus on the route tables. 

even you set a static routing, does it affect the existed vpn routing. that's a question.

i don't think you set the remote subnet would fix it. 

and if you set 1.0.0.0/1, what's the point in the 3rd rule?
