I'm looking for a service that I can run on a VPS so that i can expose my game servers to the public without having to do a port forward on my home IP.
Basically I want some kind of playit.gg or ngrok alternative where I setup a tunnel between the game server and the external proxy, and i can connect via the domain of the external proxy + port.
Anyone have some suggestions to try?

ive seen that, but can it do udp traffic? im planning on exposing a bedorck server.
looking at the project page, it doesnt seem to say that it supports udp
North Pacific hake

so ive got the server and client setup. however when trying to run the client, i get this on my home server
2025-05-10 22:35:27.495 [I] [sub/root.go:149] start frpc service for config file [frpc.toml]
2025-05-10 22:35:27.495 [I] [client/service.go:314] try to connect to server...
2025-05-10 22:35:27.519 [W] [client/service.go:317] connect to server error: dial tcp vps.ip: connect: no route to host
2025-05-10 22:35:27.519 [I] [sub/root.go:167] frpc service for config file [frpc.toml] stopped
login to the server failed: dial tcp vps.ip:2333: connect: no route to host. With loginFailExit enabled, no additional retries will be attempted

the vps im using is an oracle vps, and ive already setup a network sec group for allowing traffic on port 2333
this is what nmaping the vps results in 
cheese@elitedeskDebian[~/frp] $: nmap -sT -p 2333 vps.domain
Starting Nmap 7.93 ( https://nmap.org ) at 2025-05-10 22:37 EDT
Nmap scan report for vps.domain (vps.ip)
Host is up (0.021s latency).

PORT     STATE    SERVICE
2333/tcp filtered snapp

Nmap done: 1 IP address (1 host up) scanned in 0.10 seconds
on my vps. the frp server is indeed running and listening on port 2333

no other firewall on the machine?
seems like neither of them are getting a response they particularly like
or did you possibly misconfigure considering you didnt send either config
@North Pacific hake or did you possibly misconfigure considering you didnt send either config
Finnish HoundOP
i will send both, gimme a sec
frpc.toml on home server
serverAddr = "vps.domain"
serverPort = 2333

[[proxies]]
name = "bedrock-server"
type = "udp"
localIP = "127.0.0.1"
localPort = 19132
remotePort = 19132
frps.toml on vps
bindPort = 2333
@North Pacific hake no other firewall on the machine?
Finnish HoundOP
on teh vps itself, ufw/iptables
North Pacific hake
and ur sure you dont have a misconfig
Finnish HoundOP
not that i can see, anything else i need to provide?
let me sanity check and see if i applied the firewall rule in oracles side
yep. its enabled

North Pacific hake
i meant in the firewall yeah
ufw/iptables
Finnish HoundOP
i just canibalized whatever i made for rathole to use in frp

gimme a sec

theres other ports because i host other things on the vps along side frp
North Pacific hake
oh also just figured id mention i seriously recommend using either some sort of vpn or tunnel OR set up token auth on frp
since no auth is as you may imagine a bad idea
