These were *all* connections from 192.168.1.3 (another host
you haven't mentioned earlier!) to 192.168.1.52. 

After you had entered the iptables logging rule, did you try to
access your Linux box Apache server from the outside? Or what
else did you do actually to get those log messages?

[One could modify the iptables rule to *not* log connections coming
from your LAN (192.168.1.0/24), but that was not my intention. I
wanted to see your port 80 traffic at the packet filter level.]
