config firewall mysql 3306 using private IP
Hi, I have 2 Linodes
A) WebAPP
B) MYSQL
I've created private IP's and they both talk to each other over 192.*
I have created a rule on B to talk to A using the private address with default netmask of /32
It stops working as soon as I turn the FW on :(
appreciate any pointers?
Thanks

Hi,
Created a MySQL outbound connection on A (3306) and it worked.
😎 Thankyou
It totally escaped me that I needed to let comms out!

You do realize that communication between a MySQL client/server is two-way, right? Create a rule on A to allow it to talk to B.
You don't need the net mask if the IP address(es) are fully-specified; i.e., 192.x.x.x. If an IPv4 address is fully-specified, it can only have a net mask of /32.
