Mirroring Mysql databases - and secure tunneling, while I'm at it.

[Andy Holyer]

I've looked in the docs, and used google, and I need a quick steer as 
to the best way to proceed.

Our company is running two servers: one is a public web/mail/dns server 
sitting in a rack at Telecity, the other one is sitting here right next 
to me, and should never be seen outside of the office. Both are running 
FreeBSD-CURRENT. Both carry MySQL databases: the public one will carry 
cyrus mail, and authentication data for a radius server, the private 
one will carry our customer account data.

What I'd like to do, following my principle that buildings tend to burn 
down one at a time, is to set the two databases to mirror each other, 
so that we would be able to reconstitute either database if the need 
were to arise. I'd like this to be as easy and automatic as possible. 
Is there a standard vanilla way of doing this, or do I have to get 
inventive?

On the same tack, I'd like to have an encrypted pipe between the two 
servers (over which this company-confidential data will travel). Since 
one of the servers is behind a NAT (and soon will be behind a firewall, 
too), I'd like to use CIPE rather then IPSec. Am I correct in finding 
that CIPE is not implemented on FreeBSD? Do i have to use IPSec?

Thanks for any leads.
