Can someone help me translate this excerpt from my syslog.

2004-10-08 16:08:18 User.Warning 192.168.10.1 klogd: ACCEPT IN=br0 OUT=vlan1 SRC=192.168.10.10 DST=204.209.9.16 LEN=48 TOS=0x00 PREC=0x00 TTL=127 ID=26380 DF PROTO=TCP SPT=7637 DPT=7777 SEQ=1727272745 ACK=0 WINDOW=16384 RES=0x00 SYN URGP=0 OPT (020405B401010402)

I'm running windows 2003 server, this particular line is in my syslog file approximately every 2 hours, sometimes more often...I'm behind a Linksys Router with the following open ports
25, 80, 110, 443, 6000-6004.

TIA
