I have deployed a couple of WAAS units across a link and have issues.
If I set everything to pass-thru, everything works OK (as no traffic is hitting any classifiers). The top line of my policy is basically a match-all pass-thru (just for testing).
All ethernet ports are nailed to 100M/FD and run with clean stats.
If I disable the pass thru rule and allow traffic to hit classifiers in my policy, I get issues for any classifiers that apply any form of acceleration.
I have captured data using tethereal on the WAE's and am seeing "TCP ACKed lost segment" messages on the ACK frame of the SYN-SYN/ACK-ACK sequence of the TCP setup. I see this on the WAN port of one of my WAE's.
Is this a symptom of a stateful firewall in my service providers network that is disrupting the WAAS discovery method ? My SP says that there are no FW's in the path, but I'm starting to wonder if I'm getting the whole story here.
The code is 22.214.171.124.
If I physically back-to-back the WAE's on the bench via a test router, they work fine!
Any ideas ?
