This problem has go tme stumped!!!! I have netfilter setup (v 1.2.8.13) on a Fedora Core 1 box. It seems to be working fine except that I it is dropping DNS requesets from XP clients. Win2K and NT clients work fine. If I do an NSlookup on the XP box it resolves names fine. If I try to connect ot the pages it will connect once or twice but then iptables starts dropping all the DNS requests on their way out. Heres a syslog entry. Jun 14 10:00:31 fw kernel: IN=eth1 OUT= eth0 SRC=192.168.0.19 DST=***.***.***.*** LEN=61 TOS=0x00 PREC=0x00 TTL=127 ID=26601 PROTO=UDP SPT=1029 DPT=53 LEN=41 I don't think that iptables is the problem since every other PC works fine. I've even looked at the packets in Ethereal but can't work out why this is happening. Has anyone else come across this?? Cheers for any help Marc.
