Haha I figured that would do it too, and so I do currently have that toggle on, but it doesn’t appear to make the IP address of the ISP router accessible. " xxx.xxx.x.xxx took too long to respond (ERR\_CONNECTION\_TIMED\_OUT). It’s worth mentioning that it DOES in fact work when WG client is turned off. ---

Does the ISP router have a private address or a public one? Because you told before that the ISPs IP is now on the Flint2, so you enabled IP Passthrough? ---

That is correct, the IP address of the ISP router is now a private one, since the WAN IP is now on the Flint 2. I can access the ISP router if WG client is off, but also want it to work while on. ---
