Networking - Whitelist ports does not work as expected

[girish]

@BrutalBirdie Whoops, the filename is wrong. The correct filename is /home/yellowtent/boxdata/firewall/ports.json.

# cat /home/yellowtent/boxdata/firewall/ports.json
{
    "allowed_tcp_ports": [ 10050 ]
}

# systemctl restart cloudron-firewall
# iptables -L -n | grep -i 10050
ACCEPT     tcp  --  0.0.0.0/0            0.0.0.0/0            tcp multiport dports 10050

Now it's working as intended.
I will create a PR for the docs.

Has been done already, because it's not live yet I thought I could do that.

Thanks

This only works for TCP right now.

@girish How would be the syntax to open several ports? I'd need RStudio server (8787) and Geoserver (8080).

Is it comma separated, semicolon separated or a line per port?

Thanks a lot for the support!

[girish]

@drml It's JSON, so it would be something like

{
    "allowed_tcp_ports": [ 8787, 8080 ]
}

@girish are udp ports added to Cloudron 6.x?

[girish]

@robi No, we haven't added it. What is the use case for UDP ports?

[robi]

@girish mosh, video streams, etc any other app using udp

[BrutalBirdie]

I would also enjoy UDP being supported this way.
Since I can still just do it manual via iptables why not give the user a easier way.

@robi @BrutalBirdie done! https://git.cloudron.io/cloudron/box/-/commit/4287642308081d27dcc160f845fd5dedb27eb481

That was fast.
