People are now timing out. I used the sapphonie script but it seem don't work out of the box
Edit: It look like udp-spam is triggered when players connect. Here is a hint from a line of /var/log/syslog :
<|srcds-ipt|> udp spam: IN=ens18 OUT= MAC=6e:72:b5:8e:ec
e:aa:e6:73:44:d6:c6:08:00 SRC=194.118.68.64 DST=192.168.0.112 LEN=74 TOS=0x00 PREC=0x00 TTL=113 ID=55803 PROTO=UDP SPT=49919 DPT=27018 LEN=54
my server is L4D2 on port 27018. Any help ?
