At best it will add whatever the extra hop is and any network congestion. My VPS host is 2200km away. I should find a closer one… but it adds 160ms with some spikes in the 200-300 range. This is round trip 4400km roughly All things considered not too bad. My VPS is a 1vCPU, 1GB ram, 1Gbit unmetered, only as wireguard server. Hope that helps.

I sent you a message They are bit bare bones compared to other host but I haven’t had any issues with them in over a year. On the wireguard side you’re looking for a spoke and hub setup.

This covers it fairly well. https://www.procustodibus.com/blog/2020/11/wireguard-hub-and-spoke-config/

Good luck.

I’m in the same boat so I setup a $2.50/mo VPS and that’s my gateway. It took a little bit to get the nftables on vps to work right. I’d recomemned tailscale or similar if you want easy, though I’ve not ever used them myself.
