arp cache issue

["Snyder, Ryan" <RSnyder@xxxxxxxxxxxxx>]

Hello,
  I was wondering if any one can help me, I received this email address from
Alan Cox.

  I am running CheckPoint Firewall under Linux 2.2.19.  The Firewall is
working fine,
but on the interface that is connected to the Internet via a Cisco router
has over 950
entries in the arp cache.  I understand this is normal, but since there is
only one
route to the Internet, is there a way to not have Linux to an arp cache
lookup, or even
a setting to make the cache size much bigger?

  I have looked into running arpd, but I am kinda fuzzy about running daemon
stuff in
userspace; espically on a firewall.

Any help is greatly appreciated.

Thanks,
Ryan Snyder
