GWIA: "Accepted HTTP Connection" Message

Greetings all--

We're running GW5.5ep, sp5 on Novell 6.5sp1a. While having a wonderful
time rebooting the server this morning, I happened to notice a message
on the GWIA screen that said:

"Accepted HTTP connection with [ip address]"
followed by
"HTTP session ended [ip address]"

both with the same time stamp. The IP address is not one of ours. I've
never seen a message like this before, is this something I should be
worried about? Is someone trying to use my server as a relay? Or is
this normal and I've just not seen it before?

Thanks in advance.
