Inside firewall access to outside firewall MySQL server

I have 2 Suse 9.1 boxes with similar configurations. I'm in the
process of moving some PHP code from one server (192.168.0.100) to
another (192.168.0.102). MySQL is running on each server, and the same
PHP code can access its respective localhost databases and make queries
with no problem.

However, the code on the old server (.100) can access a MySQL server
(12.xx.xx.50) outside the firewall (192.168.0.1), while the code on the
new server cannot.

There is NO firewall rule regarding the two servers -- they are NOT
being accessed from outside the firewall.

Give me an idea where to start looking for the cure to the problem.

I am using the same routines, including the same user names and
passwords, from the 2nd server. The MySQL server sees the same IP
address (the firewall IP number() for the new server as the old server.
So, there is not a difference, is there?
