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
