Public bug reported:
I did this same test on ubuntu 22.04 and 24.04 :
All policies are in ACCEPT
iptables -A INPUT -i any -p tcp --dport 22 -j ACCEPT
iptables -A INPUT -i any -j DROP
If i do a telnet on the server (from an external host) on port 22 it's ok
If i do a telnet on the server (from an external host) on port 8888 i got a
reject !!! (it's not a drop)
If i do a nc -l -p 8888 on the server and then telnet on port 8888 the
connection is authorized !!!
I try this on a 22.04 and on a 24.04 ubuntu server and i got the same
results. The second rule is not applied
