Howdy all, I'm attempting to use a Toshiba TECRA 8000 running 5.0-release as the firewall for my home network. It's running right now, but I'm seeing some sketchy network behavior and I think it's one of the NICs. Basically, when I'm doing something fairly network-intensive (like large NNTP downloads) my bandwidth usage fluctuates wildly. I also will get a lot of connections reset and such. I think it's my ed1 interface (which is my inside interface), because when I had ed1 as my outside interface and in promiscuous mode (for snort) I was getting a lot errors like: Feb 14 15:00:37 elijah kernel: ed1: NIC memory corrupt - invalid packet length 4 When I changed my dc0 interface to be my outside, promiscuous interface, these errors went away. My current dmesg info is as follows. ed1: <Linksys Combo EthernetCard> at port 0x100-0x11f irq 11 function 0 config 16 on pccard0 ed1: address 00:e0:98:88:91:84, type Linksys (16 bit) ukphy0: <Generic IEEE 802.3u media interface> on miibus0 ukphy0: 10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, auto dc0: <Xircom X3201 10/100BaseTX> port 0x1000-0x107f mem 0x88002400-0x880024ff,0x88002500-0x8800257f irq 11 at device 0.0 on cardbus1 dc0: Ethernet address: 06:00:06:29:52:90 miibus1: <MII bus> on dc0 tdkphy0: <TDK 78Q2120 media interface> on miibus1 tdkphy0: 10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, auto Anyway, so I recently got a Xircom 10/100 cardbus NIC to replace my linksys (ed1) card. However, when I boot up with this NIC, I get to the point where my interfaces are going to be configured (after setting hostname) and the machine locks up. Here's the dmesg info for the new card. dc1: <Xircom X3201 10/100BaseTX> port 0x1080-0x10ff mem 0x88002000-0x880020ff,0x88002100-0x8800217f irq 11 at device 0.0 on cardbus0 dc1: Ethernet address: 06:00:10:a4:03:3f miibus0: <MII bus> on dc1 Would it help if I rebuilt my kernel and specified the irq, mem and port for dc0 and dc1?
