I've been troubleshooting an problem between an HTTPS server and some clients connected to my site through VPN.
Basically, My topology would look this way:
SERVER - 6509(with FWSM) - couple of switches just forwarding traffic in the middle, MY VPN concentrator and finally users connected through this concentrator.
I've been doing some sniffing and all of them shows a couple of TCP Zerowindow flags coming from the server and of course to me this issue sounds like to be something on the server side. Have you guys deal with something like that before?
If you guys agree on what i'm saying, anyone knows if there's an good document on the WEB, so i can send customer as an additional prove?
Thanks in Advance,
