I'm trying now since a few day's to get dns working. I'm using dsl(dhcp). port 53 is at accept, no drop/logdrop entries in any tables- but in the lifelog I see all packets/port 53 being dropped:
Mar 1 17:57:28 (none) kernel: UDP Drop: IN= OUT=ppp0 SRC=80.131.232.10 DST=192.42.93.30 LEN=60 TOS=0x00 PREC=0x00 TTL=64 ID=0 DF PROTO=UDP SPT=1029 DPT=53 LEN=40
