Helo,I have a client that want to install new ASA (5510) in their network.

and then I did some experiment to implement it. the topology is like this :

I can successfully ping from host 192.168.12.2 to 192.168.11.2, but I can't do remote desktop from those host.

then I use wireshark to capture packet in my computer and it says that TCP ACKed Lost Segment.

"1373","164.538081","192.168.11.2","192.168.12.2","TCP","47785 > ms-wbt-server [SYN] Seq=0 Win=8192 Len=0 MSS=1460 WS=2"

"1374","164.538993","192.168.12.2","192.168.11.2","TCP","[TCP ACKed lost segment] ms-wbt-server > 47785 [RST, ACK] Seq=1 Ack=1407706213 Win=0 Len=0"

I can guarantee that both computers are remote desktop enabled and all firewall have been disabled.

please help, any suggest would be great .

thanks .

sincerley yours
