My server is up and running … i tried the canyouseeme website… i tried the info json one … all seems good … I added rules to open the port etc… Nothing seems to be working and i’m out of options/ideas.

Please help ? :frowning:

What OS are you using?

Windows: 30120/40120 both UDP and TCP
Linux: ufw allow 30120,40120 && ufw reload

Why do you need to open port 30110, its not used for anything unless you setup a separate “sv_master1” which most don’t.

If people are using a separate call sv_master1 you should only allow TCP through and preferably only allow it through as a response as ingress, as to my knowledge, does not send HTTP requests directly to the server.

Windows!

Open Windows Defender Firewall:

  1. Inbound Rules, New Rule…, Port, TCP & Specific local ports:… “30120, 40120”, Allow the connection…
    Domain
    Private
    Public,
    Name… “FXServer-Inbound-TCP”, Finish
  2. Repeat step one with UDP in place of TCP, Name… “FXServer-Inbound-UDP”, Finish
  3. Outbound Rules, New Rule…, Port, TCP & Specific local ports:… “30120, 40120”, Allow the connection…
    Domain
    Private
    Public,
    Name… “FXServer-Outbound-TCP”, Finish
  4. Repeat step one with UDP in place of TCP, Name… “FXServer-Outbound-UDP”, Finish

If this doesn’t help with the ports, check YouTube or browse the forums – more content around there. In the case this doesn’t resolve the initial problem, reply further.

Not sure what the issue is. I’m unfamiliar with “Guardian”, could that be intercepting or modifying packets?

11

Nah Guardian is a script that detects people’s whitelist from discord roles

Found the problem ! It was something very specific and new to OVH that i didnt know about. Thanks !

15

Was it the OVH auto-DDoS protection firewall system? I’ve dealt with that in the past and it just came to mind.

Nope, they have for their game dedicated servers a section called network where you can enter IPs used by games into a game firewall thing to open the port to… So even if i was opening the ports on the 'host pc" this firewall thats in my client dashboard would block them.
