Ping/access webserver behind CGNAT?

ibroughtashrubbery@lemmy.ml to Selfhosted@lemmy.world – 7 points –

Hi guys! IN a bit of a rush, I installed a server on a place where I knew I'd have trouble reaching, as their router is behind CGNAT. I want now to start installing some VMs etc. At the moment all I have is a VM running Windows running Teamviewer for remote access (I know, I know). I have most of my services hosted on a local home server that runs rather well and has plenty of bandwidth. Among these, there's a PiVPN running on my home server that works rather well. Is there a way I could make that remote CGNAT server connect to my VPN and be reachable/pingable/show webpages locally?

Thanks!

you could use tailscale for that, it should be able to punch through the CGNAT

As someone else who uses Tailscale behind a CGNAT, this indeed works. I use it for accessing my home server from the office for a year now. You can't quite self host anything public facing but anything on your tailnet can talk to it just fine.

Theoretically a VPS proxy into the server over the VPN could work for devices not capable of running tailscale but your mileage may vary.
