Hello everyone! Excuse me for the question if you are very new to them, but what can I do if UDP ports are blocked? I try to allow Minetest, for example, but although it appears that the game is "transmitting", none of the devices connected to the same network connects. And it is not a problem of the game, because it has also happened to me with other software, such as WO Mic, where it indicates a message that the UDP port 8120 is blocked, if I remember correctly.

hey @themiauxddev23 !

I'll need more info about your system: OpenSnitch version, distribution, kernel version and if the file cat /sys/kernel/debug/tracing/kprobe_events exists.

On the other hand, could you change log level to DEBUG (Preferences -> nodes) and try to connect/reconnect minetest, or launch it again?

Once you reproduce it , post the log /var/log/opensnitchd.log please.

thank you @themiauxddev23 !

The eBPF monitor method is working fine and connections from minetest being intercepted 👍 (sometimes the eBPF monitor method doesn't work and we have to fallback to ProcFS, which is not as reliable as eBPF):

[2022-08-21 17:51:06] new connection udp => 51168:127.0.0.1 -> 127.0.0.1:30000 uid: 1000
[2022-08-21 17:51:06] DBG /app/bin/minetest-> 127.0.0.1:30000 (mallow-until-restart-simple-app-bin-minetest)

none of the devices connected to the same network connects

Do the devices connect to this machine? or how does it work? As far as opensnitch goes, it's working as expected (outbound connections being intercepted and allowed/denied).

Are there any other firewall rules that could be blocking inbound/outbound connections?

Maybe it's too obivous to ask this, but did you try to disable opensnitch? O:)

other software, such as WO Mic, where it indicates a message that the UDP port 8120 is blocked

One way of checking if it's opened is by executing nmap: nmap -sU -p 8120 x.x.x.x If opensnitch prompts you to allow/deny it, it usually indicates that opensnitch is working correctly and the port is not blocked.

Regarding this error:

Error while running firewall rule, ipv6 err: exit status 4` I 
rule: [-I OUTPUT -t mangle -m conntrack --ctstate NEW,RELATED -j NFQUEUE --queue-num 0 --queue-bypass]

Did you disable ipv6 system-wide? There should be a fw rule for ipv6 if it's not disabled: ip6tables -t mangle -L

by the way, check [x] Debug invalid connections under Preferences->Nodes . Sometimes we intercept outbound connections without an associated process, which usually indicates that it's an invalid connection, so we discard those connections. But other times those connections might be valid.

With that option checked, opensnitch will prompt you to allow/deny "Unknown connections"
