G. ---- Original Message ---- From: Dany Nativel Date: Wed 1/21/04 15:00 To: Brandon Holland, m0n0wall at lists dot m0n0 dot ch Subject: Re: [m0n0wall] Network getting slower after 20 minutes Now I'm lost ! It's not the switch, nor the RTL8139 chipset, nor the memory. The PC is an old Pentium 166. The good news it I'm looking at a Soekris board but I like to understand what's going on because this box has been running Ipcop for years without a problem. I just want to make sure it's not a hidden bug that would compromise other platforms !
