How to reach different services on the same machine via name instead of ip+port? (lemmy.world)

On my Lan I have 192.168.1.111 hosting a bunch of various services not containerized. All connections are done either from my internal lan or from wireguard going through 192.168.1.111 so no external traffic bar wireguard.

I've set the host name of 111 in the hosts file inside the router and 111 and it works for all devices expect the ones connecting via wireguard.

But I dont want to have to use hostname+port for every service, I'd like each service to have its own name. I'd also like certs.

Can someone point me in the right direction for what I need to do? I'm thinking maybe this requires a local DNS server which im hesitant to run because im happy using 8.8.8.8.

For certs do I create a single cert on the 192.168.1.111 and then point all the applications to it?

Reverse proxies! They can redirect based on the dns name used to get to them. This is based on layer 7 data though so just http(s) services and not multiple ssh tunnels for example.

k3s/rke2 (k8s distros) do it automatically with Traefik when you use the gateway or ingres apis

Also for DNS a fun option is sslip.io which lets you do -192-168-1-10.sslip.io and it redirects to your ip but with a dns name added.

Though your router likely has an easy way to add local entries for dns and also upstream for the rest (i.e. 8.8.8.8)
