Using RHEL 6, two hosts (A, B) each with two NICs, Each host has one
NIC on each of two VLANs. Tomcat on Host_A rying to connect to MySQL
on Host_B, port 3306. iptables on Host_B looks open (0.0.0.0) for
TCP/3306.
Host_A_NIC_0 can connect to Host_B_NIC_0 TCP/3306
HOST_A_NIC_1 can NOT connect to HOST_B_NIC_1 TCP/3306.
They are 1 IP off and NIC_1 can ping NIC_1, but not connect TCP/3306.
Thoughts on how to figure out why when iptables looks open?
