Some questions before installing OpenWrt on R7800

[tectonic]

I tend to agree with previous posters: on the surface, your set-up can be simplified.

Having said that, I also moved my R7800 from dd-wrt to OpenWrt (though, I've got completely different hardware and a different topology now). Based on (fairly) recent experience:

@Jorman

• Openvpn Server (to connect directly to the router when I'm out)
• Openvpn Client (connected to PIA)
• Static ip for some devices (I don't think this can be a problem, just to know)
• All the traffic from/to NAS must be under VPN, in order to do that on dd-wrt I use a pbr script (not mine), maybe here is not needed. Anyway, NAS can navigate only through VPN.

@Jorman

I need to reach my NAS when I connect myself over Openvpn Server, but the NAS in under pia vpn. In order to do that I only set a iproute to my NAS, I don't think this is a business of OpenWrt, but maybe I'm wrong!

I had all this running on dd-wrt and switched successfully to OpenWrt. Personally, I found VPN Policy-Based Routing + Web UI -- Discussion to be the 'path of least resistance' in terms of PBR.

Have fun!
