I have a Cisco 2621 running IOS version
The setup is a very simple one. I have
a Windows XP sitting behind the Cisco 2621.
On the Windows XP, I run Emule and Bit
Torrent on the WinXP box. After about
an hour, the Cisco 2621 freezed up and
became un-responsive. The only solution
is to manually turn OFF/ON the power
button on the 2621 router.
Here is my configuration on the router:
ip address 188.8.131.52 255.255.255.248
ip nat outside
ip address 192.168.1.1 255.255.255.0
ip nat inside
access-list 100 permit ip 192.168.1.0 0.0.0.255 any
ip nat inside source list 100 interface F0/0 overload
I have a 30Mbps download and 5Mbps upload. When the router is running
the # of NAT translation is about 200 and
the throughput is about 5Mbps download and 2Mbps upload.
What could be the issue that makes the router locked up after an hour. If I
stop emule and bit torrent, the router
can stay up and running for days without
Last but not least, if I replace the
Cisco 2621 with a Checkpoint NGx R65
Secureplatform firewall, I have no such issue.
When the rourer is up and running with
emule and bit torrent prior to locking up, cpu is about 40% and memory is about
Any ideas anyone? Thanks.
