Scaleway how the firewall work?

ZweiTiger

I run a gameserver on port: 2106 but its says its closed. Checked with this: http://www.yougetsignal.com/tools/open-ports/ . Got an online.net dedicated server and works great! Whats the problem? Why the 2106 port is still closed? Any suggestion?

1   TCP outbound    0.0.0.0/0   2106    accept  
2   TCP inbound     0.0.0.0/0   2106    accept  
3   TCP inbound     0.0.0.0/0       accept  
4   TCP outbound    0.0.0.0/0         accept

Game server use udp.

You need to reboot the server to activate firewall rules. But mad but that's what there support told me

Added UDP , rebooted still closed. I hate this firewall like at runabove... Ah..

Opened a support ticket. we shall see

They said use iptables to open or close ports. And thats all. They only block the SMTP port at their firewall

By default their firewall only blocks SMTP, and no reboot is needed to take effect. Are you sure your gameserver works on the ARM architecture?

Yes its works. Tested when there wasnt any firewall and run very well.

I test if ports are open or not. but only 80,21,22 port is open thats why i cannot join hmm..

@ZweiTiger
Ports will only show as open if there is a service listening on the port. Hence 80,21,22
Webserver,FTP,SFTP/SSH

I believe the application you are using is not listening correctly. Possibly no support for ARM.

No you don't but it does take a few minutes between setting something on the firewall and it actually applying. Also it's a stateless firewall so it's not so useful if you need state tracking (E.g allow established,related)

@ZweiTiger : I'm not sure you test correctly if your UDP port is open: most websites like "yougetsignal" only test for TCP.
Maybe try this one: https://pentest-tools.com/network-vulnerability-scanning/udp-port-scanner-online-nmap or http://www.base64online.com/port-check.php or another websites.
Or try to connect to your server with nmap or your game.
