The logs on my mail server are filling up with this kind of thing:
Oct 19 17:03:51 bnofmail kernel: REJECT: IN=eth0 OUT=
MAC=XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX SRC=195.140.240.6
DST=XX.XX.XX.XX LEN=189 TOS=0x00 PREC=0x00 TTL=52 ID=6284 DF PROTO=TCP
SPT=25 DPT=32776 WINDOW=65535 RES=0x00 ACK PSH URGP=0
The source port is always 25 and the destination is a high-numbered
port. The destination address is the private IP of the server. These
seem to be related to outgoing email connections based on the source
IPs, but I don't know why they are not part of an established
connection. The mail server seems to be running just fine regardless of
these blocked connections.
Any ideas?
