How are you making services remotely accessible?

stevecrox@kbin.run to Selfhosted@lemmy.world – 99 points –

I need help figuring out where I am going wrong or being an idiot, if people could point out where...

I have a server running Debian 12 and various docker images (Jellyfin, Home Assistant, etc...) controlled by portainer.

A consumer router assigns static Ip addresses by MAC address. The router lets me define the IP address of a primary/secondary DNS. The router registers itself with DynDNS.

I want to make this remotely accessible.

From what I have read I need to setup a reverse proxy, I have tried to follow various guides to give my server a cert for the reverse proxy but it always fails.

I figure the server needs the dyndns address to point at it but I the scripts pick up the internal IP.

How are people solving this?

I'm afraid that I don't have any guides. But, you're halfway there anyway. Which one of these methods do you prefer? I can maybe give you some pointers.

I like the idea of using the VPS and forwarding requests via WireGuard. I’m about to switch my setup from using NPM to Traefik. The next step after that may be to put the VPS in front of it all.

My setup looks like the following:

/etc/wireguard/wg-vps.conf on the VPS
-----------------------------------------------------
[Interface]
Address = 10.8.0.2/24
ListenPort = 51820
PrivateKey = ********************************************

# packet forwarding
PreUp = sysctl -w net.ipv4.ip_forward=1

# port forwarding 80 and 443
PreUp = iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 80 -j DNAT --to-destination 10.8.0.1:80
PreUp = iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 443 -j DNAT --to-destination 10.8.0.1:443
PostDown = iptables -t nat -D PREROUTING -i eth0 -p tcp --dport 80 -j DNAT --to-destination 10.8.0.1:80
PostDown = iptables -t nat -D PREROUTING -i eth0 -p tcp --dport 443 -j DNAT --to-destination 10.8.0.1:443

# packet masquerading
PreUp = iptables -t nat -A POSTROUTING -o wg-vps -j MASQUERADE
PostDown = iptables -t nat -D POSTROUTING -o wg-vps -j MASQUERADE

[Peer]
PublicKey = ********************************************
AllowedIPs = 10.8.0.1

/etc/wireguard/wg-vps.conf on my home-server
---------------------------------------------------------------
[Interface]
Address = 10.8.0.1/24
PrivateKey = ********************************************

[Peer]
PublicKey = ********************************************
AllowedIPs = 10.8.0.2
Endpoint = :51820
PersistentKeepAlive = 25

Now, just enable the tunnel using sudo systemctl enable --now wg-quick@wg-vps. Make sure that the port 51820, 80, and 443 are open on the VPS. Now, allow 80, 443 through the firewall on the home-server (not on the router, just allow it locally), and it should work.
