I do have my own web server running centos 7 i could use. I am planning to buy a small mini-pc that will be running home assistant and frigate for recording my camera’s and integrating AI detection into my smart home. It seems the best installation for that is debian.
I have a router that is using a wireguard vpn, that does not allow port forwarding, so i need an alternative to access the mini-pc.
Now, of course there’s some things to be found when googling, but my preference goes to the most easy-to-use solution as i’m not great with linux, i just mess around digging through configs, copy-pasting instructions and getting stuff done that way. This is why I wanted to ask you guys for advice =)
Would appriciate assistance!
Set up a reverse tunnel to the outside box that you want to get in from.
For example, from the inside machine:
ssh outsidemachine -R 2222:localhost:22Then on your outsidemachine:
ssh -p 2222 localhostMaybe run top or something just to keep traffic going across so that firewalls don’t drop your connection.
This is what I’ve done too. I am almost certain it is less performant than some of the other options out there but I like that it is simple and using a tool I know. If this was a major use case of mine, I’d probably do more playing and get it working with something else but this works for now.
Also check out autossh and some of those tools
Personally I use wireguard on custom port, but you can try Tailscale or zerotier?
What do you mean “a router that is using a wireguard vpn” ? Why not just add your device as an endpoint in wireguard?
I want the whole house to be automatically protected. Incl many smart home devices. So every device that connects to the router, is going through the vpn.
And from there to the linux pc? Why not just add tunnel to your external device?
Setup a vpn pn a vps. Then connect your server as a client. Connect your other device as client and use the vpn nerxork address to access your server
I run Wireguard at my public VPS. I run Wireguard on my clients at home. I have Wireguard on the server configured to route via iptables, the ports I desire to send that traffic to my home machines.

net.ipv4.ip_forward=1I’m using Twingate, it’s safe and works fine !
Ipv6 only is an option or use tailscale
Tailscale or Cloudflare Tunnel with Access Rules
If you have a VPN router, your router literally has remote access built in as a feature. The VPN can be connected to remotely, and allow you to access locally hosted services. I use mine for such a purpose. When configured correctly, your VPN connection makes your device get treated like it’s on the local network.
I had so much trouble setting up the router with vpn that i’d really rather not make big changes…
I would suggest ZeroTier, its opensourse and pretty smart. Clients for all platforms are available
If you haven’t read this information in the 100’s of other post on this subject or the wiki what good would it do to answer it again?
I want the easiest solution
