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 have a wireguard tunnel set up between my home server and the VPS, with persistent keepalive. The public domain name points to the VPS, then I have it set up (simply using iptables) so that any traffic there in port 80 and 443 is sent back to my honeserver and there it’s handled by caddy, and sent to the actual service.
The only ports I need to open are 80 and 443 on my VPS to make this setup work. So, no open ports on my local machine. This does however require you to pay for VPS. Since you aren’t doing much on it though, you can get away with a cheap one. I have a $12/year VPS from Rack nerd that I use for this job.
For completely free options, you can do one of three things. (That I can think of. There are probably more ways.)
P.S. If you need help setting any of these up, lmk.
Your setup sounds great! I hadn’t come across something like that and I’d love to try it out, myself. Do you have a guide or any other resources with more info? I’m currently using a reverse proxy, but I’m not excited about the open ports, even with firewall rules keeping them contained.
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 = 25Now, 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.Thanks so much! Hopefully I’ll be giving this a try soon.
