Hi,
I am facing replication issue while setup the gateways and I can see replication is not working between two DMZ gateways which are on the same subnet.
An error in mysqld log is [ERRO] Slave I/O: error connecting to master, error_code:2003
DMZ gateways not able to communicate using port 3307 as I understand.
iptables and selinux switched off.
Appreciate your help.
Thanks
V G
