Hello Everyone,
I have ACE10 Module in my switch core 6509, my context "Proxy" was criated for balance connections to Forefront TMG Servers, this balance needs original client IP Address connections end to end in the solution.
My problem is: The clients are complaining of slowness connection to the internet, i captured the traffic in the ace capture feature and i see some RST packets and severals checksum error packets in pcap file.
The topology is:
Client -> ACE VIP VLAN 81 -> RSERVERS VLAN 80
Vlan 80 is in L2 mode(no interface vlan in the switch core 6509, route occurs through the ace appliance).
The IP address 10.96.200.6 is the gw for rservers.
system: Version A2(3.4) [build 3.0(0)A2(3.4)]

If needed, i can send the pcap file for analyse.
Tks a Lot.

Hi Rafael,
Are RST's coming from ACE? What if you access the server directly? If you could raise a TAC case we would do in-depth analysis of the problem.
