I am trying to allow mysql communications between two of my servers for
replication purposes. I have tried two iptables statements, but instead
of allowing the communications, it stops all communications. I can no
long ping the second server or SCP to it. Very strange. Here are the
two things I've tried:
1) iptables -A INPUT -p tcp -m tcp --syn -s 66.232.241.121 --dport 3306
-j ACCEPT
and
2) iptables -A INPUT -p tcp -m tcp --syn -s 66.232.241.121 -j ACCEPT
What am I doing missing here?
Thanks,
Scott
