We installed a WAAS in a bank environment and configured WCCP to redirect all traffic between the HO and Branch to the WAE devices
Everything worked fine except the AS400 replication between the 2 sites, it is sooooooo slow and when we denied the IP's of the AS400 from the WCCP REdirection, it worked very well.
NOTE: I created a new Policy with a classifier that match the IP's of the 2 AS400 and configured the application as REPLICATION, with FULL OPTIMIZATION.
Did any faced problem with the AS400 when implementing WAAS?
I will test by removing the new configured policy and send the AS400 traffic over the WAAS again.
