I have a very strange problem on the network since I put WAAS.
The architecture is as following :
Central site with access to remote sites else via MPLS operator network (provinding its routers) else via IPSec VPN with firewall.
Recently it was decided to try the WAAS solution to enhance performance on a particular remote site.
So I have one WAVE274 as manager on the central site, one WAVE474 (inline) between the network and the operator router leading to approximatively 100 remote sites, a WAVE474 on one remote site only (inline too).
All was properly functionning : Optimization and so on between the 2 WAVE474, no action for other remote sites (of course).
My problem is that access to one particular URL (really needed) from all the remote sites passing through the central WAAS box is not available anymore !!! Access to that URL is OK from all remote VPN sites and from the central site.
When putting off the WAVE474 of the central site, the URL access is regained.
I can't understand. I thought that only the traffic between 2 WAAS peers was optimized (modified) and that trafic passing through only one WAAS box was not modified (the central WAVE acting in that case as a wire).
Any idea ?
