Hi all,
I experience some strange problems after the DSL modem hangs up (every 24 hours). I want to do a dyndns update immediately after reconnect but then it looks like NAT does not work for some minutes. I made a rule to watch domain requests as these are the first things to happen. In the logfile I get a lot of entries like
2005:01:25-08:25:36 (none) kernel: ACCEPT: IN=eth0 OUT=ppp0 SRC=10.0.0.10 DST=194.25.2.129 LEN=61 TOS=0x00 PREC=0x00 TTL=254 ID=44341 DF PROTO=UDP SPT=41983 DPT=53 LEN=41
2005:01:25-08:25:36 (none) kernel: DROP: IN=ppp0 OUT= MAC= SRC=194.25.2.129 DST=217.81.192.165 LEN=222 TOS=0x00 PREC=0x00 TTL=60 ID=0 DF PROTO=UDP SPT=53 DPT=41983 LEN=202
10.0.0.10 is the internal box running named, 194.25.2.129 is the dns server of the provider and 217.81.192.165 was my external ip address then. It looks like for that moment the dns response could not be assigned to the original request, so the response is dropped. After some minutes everything works again. Maybe someone could shed some light on this.
Thanks,
Markus
