Date: Sun, 18 Jul 2004 16:50:07 -0400 [thread overview]
Message-ID: <20040718205007.GA7576@sapience.com> (raw)
I'd appreciate help here.
I disallow iana reserved and some rfc 1918 from my firewall.
The line in question is this:
cRES_LDROP all -- 172.16.0.0/12 0.0.0.0/0
which I would expect to block 172.16 to 172.31.
However I get these in my log files:
Jul 18 16:21:47 fw kernel: [FW Drop-Res] IN=eth1 OUT= MAC=<xx> SRC=172.139.140.122 DST=<myip> LEN=48 TOS=0x00 PREC=0x00 TTL=109 ID=30189 DF PROTO=TCP SPT=3477 DPT=1025 WINDOW=16384 RES=0x00 SYN URGP=0
I'm stumped - why did 172.139 get dropped here? Not that the packet
wouldn't have gotten dropped later anyway but this rule should not
have matched?
Suggestions?
