Server Connectivity Test Tool

(1/1)

soupcan:
Hi all,

I created a tool that you can use to test that your GE:S (or other Source-based) game server is reachable from the internet. Great for verifying port forwarding and firewall configuration!

Try it here: https://www.geshl2.com/server-test/

It will check if the specified TCP and UDP port is reachable and display the result. It always queries the IP address of the requestor.

If you need to test from a server that doesn't have a GUI, there's also a version that only outputs plain-text responses.

Spoiler for API Instructions:
--- Code: ---
curl https://servertest.geshl2.com/api?port=27015
--- End code ---

It will output one of:


--- Code: ---
tcpudp  # reachable
tcponly # only TCP port reachable. can't join server
udponly # only UDP port reachable. will work, but no RCON
unreachable

--- End code ---
