Forgetting to change it when an ip address changed.

We have two boxes that were briefly sitting outside of a firewall.  This
is when I implemented the TCP.INVITED_NODES parameter.  Since that time,
these boxes have been moved into a more secure area of the network.  But
since they are outside our corporate firewall I left the parameter in
place.  I've never really had any problems, except when the IP address
of the invited nodes changed.  They were NATted addresses, so it took me
a little while to figure out that it wasn't a firewall problem.

Hello,

I'm curious how many folks have used the the TCP.VALIDNODE_CHECKING, 
TCP.EXCLUDED_NODES and/or TCP.INVITED_NODES parameters to restrict
database access.

What problems did you run into with it? 

Was it worth the trouble in your opinion?

Thanks,
