Thanks a lot who has replied to me.
Basically 64.40.117.19 is foreign IP and connection from all over world
means
I've seen accesses from various different IPs to 64.40.117.119.
Before client's connection was without firewall.
I put firewall and also notified client's admin and now it seems like
everything is fine.

Joey,
a text book case? Prehaps im missing something, but see nothing in
Genbolds email which makes me consider XSS. XSS is often a small amount of
traffic, with HTML and javascript in post request content or get request
query strings.
Ganbold,
In my opinion, it's more likely it's one of the following
* brute force or dictionary attack on a login form, prehaps using a botnet
to mask the actual attacker
* DDOS, again prehaps from a botnet
* DOS, prehaps creating half open connects using a random spoofed source
addresses (try and check to see if the addresses are random, or come for a
fixed set of IPs).
* Someone looking for hidden files and directories
* An automated script scraping the website for dynamic or a large amount
of content, or some other tool which is malfunctioning
* The website is just really popular and your client needs to upgrade
their kit
Attempt to find out what kind of requests (if any) are being sent to the
server, prehaps using a tool like wireshark, and that should tell you a
little about what is going on.
Best,
Renski
Ganbold,
This sounds like a textbook case of Cross Site Scripting (XSS).
Consider filtering user output more carefully.

Hi,
Recently I have seen a lots of connections to 64.40.117.19 port 80
in
one of our clients network.
Connections are coming from all over the Internet (various
different
IPs) specifically to this IP.
Due to this problem (I guess it is DDoS) one of our router's CPU
usage
grew up to 100% and stopped a service
for a while.
What kind of problem this could be?
Has anybody seen this kind of attack before?
I appreciate if somebody can enlighten me in this regard.
thanks in advance,
Ganbold
