as i mentioned, i switched to iptables.
now, every few hours, my roadrunner connection is dropping. this was not happening with ipchains! here is the part of my log just before it happens. i tried ifup, but that doesn't help. it fails to acquire the ip address. does anyone know what is happening? is my nic dying? is it iptables? i wish i had a clue. (rat is the name of my serer)
These are outgoing DHCP packets. You need to allow those, although if you're not I don't see how you would have gotten a DHCP lease in the first place. Do you have leftover scripts in place to change the firewall rules when you start DHCP? I don't think that's needed with iptables. Also I would recommend using dhcpcd exclusively instead of pump. If you remove the pump RPM the scripts should handle this automatically. The SRC=192.168.0.1 is an RFC violation (it should be SRC=0.0.0.0).Oct 7 11:14:56 rat kernel: [UDP reject] IN= OUT=eth0 SRC=24.90.93.125 DST=24.29.99.107 LEN=576 TOS=0x00 PREC=0x00 TTL=64 ID=0 DF PROTO=UDP SPT=68 DPT=67 LEN=556 Oct 7 11:14:56 rat kernel: [UDP drop] IN= OUT=eth0 SRC=192.168.0.1 DST=255.255.255.255 LEN=328 TOS=0x00 PREC=0x00 TTL=64 ID=0 DF PROTO=UDP SPT=68 DPT=67 LEN=308
