maximum number of iptables rules?
Hi, me and a buddy of mine are working on a perl script to automate blocking of about 3000 IP addresses.
The script works fine on his box, x86. But on my box, sparc, I seem to have a limitation of 854 rules before I start to get errors and am unable to add anymore rules. Is there a maximum number of rules per chain? or overall?
Here is the information on my Sparc box.

Any help is greatly appreciated.

Tell us more about both machines - especially how much memory they each have.
