Gobbling my bandwidth?

Hi all,

I've scoured the mailing list and can't find anything, so I figure I'll start a new topic...

I'm running a Debian GNU/Linux box for a router / firewall at home. Using a 2.4.19 customed kernel, Pentium MMX, IPTables 1.2.6a, and Narc auto-configuration script for IPTables. I've got the same configuration running on a webhosting box, except its running a p4 1.5.

My problem is that intermittently (and only as of lately) has my connection been dropping to ~4000ms for a roundtrip... and after 15-20 minutes it resumes back to its normal ~80ms. Does anyone know whats causing this?

Logging is off, and afaict the rules are optimized. When I stop IPTables and just try pinging google, my ping time returns to 80... but as soon as I fire IPTables up again, it raises the ping time to ~4000ms.

Theres nothing listing in my processes (ps aux or top) that indicate anything related to IPTables or narc... I am absolutely stumped - as this has only happened in the past 2 days after 3 months of running solid.

Any and all help is greatly appreciated.
