I'd love to share. Whoever was interested in that, please let me know in
an email. Thanks for the suggestions. I really appreciate them and I'll
look into it.

5,000 rules is significant.  Have a look at the hashing examples in the 
LARTC howto for some ideas on how to slash bandwidth required. 

There is also a high performance iptables project kicking around which 
does much better for large rulesets.  Since you don't seem to need 
anything advanced I would have thought this was a drop in replacement.  
Have a look at http://www.hipac.org/index.htm - Never used it though, 
just came across it on google.

I think there is another chap who posted a few hours earlier may be 
really interested in your perl script to read users from the DB and 
build rules.  If you have any kind of traffic accounting I think he 
would be interested in that as well.   Want to share any of that...?

Good luck
