I have five 827 adsl routers in front of a 2821 for internet access. The 827's are doing all of the nat translations and the 2821 is doing cef load sharing:
ip cef load-sharing algorithm include-ports source destination
Browsing the internet works great, but it seems like large downloads
timeout often, but not all of the time. When i direct traffic to only
one of the 827's instead of the cef load-sharing randomly picking one,
then the large downloads work and do not timeout.
The 2821 is running: c2800nm-adventerprisek9-mz.124-20.T.bin
Is load-sharing the problem?
