Iptables redirect internal port - remote mysql

[grzeg]

Hi there!

I'm trying to set up remote mysql server, and got stuck.
All my clients are using "localhost" as mysql address ( mysql_connect('localhost', 'user', 'pass'); ).

New mysql server address would be sql.domain.com, so how am I supposed to redirect all "localhost" connections to "sql.domain.com" ?

I've tried some iptables rules, but couldn't find the right one.

Is there any solution or should I ask all my clients to change their mysql address?

I will be grateful for help!
Best Regards

It would be much better to have the clients change the address as anything else could have unforeseen consequences. If you really want to do it in iptables then you'd need to look at the REDIRECT or DNAT modules in the iptables PREROUTING nat chain.
