here is TOP:
FTP Server ----WXC 3400 (JWOS 6.0) ------ISG1000(6.0r8)------Internet-----NAT device-------Switch--------Client(Windows XP SP3
FTP server ip:18.104.22.168/24
WXC ip: 22.214.171.124/24
ISG inside ip : 126.96.36.199/24
remote client ip:192.168.1.212/24
remote clinet use netscreen-remote vpn client to connect ISG 1000 inside subnet by vpn tunnel.
the isg 1000 policy:
188.8.131.52/24 to Diul-up VPN any any
Diul-up VPN to 184.108.40.206/24 any any
when vpn tunnel was established ,Betweent WXC and wxc client has no NAT,they can use real ip address to visit each other .
WXC client also can connect wxc3400 establish channel (WXC use default config,TCP,NSC,CIFS was enabled)
BUT,When client download file from FTP server,it has no acceleration effect.
Could you give me some point to solve,Thanks very much.
Sorry for my bad english.

Can you please ensure that the ISG is not removing the TCP Option fields. We use this to flag the flow with TCP OPT38, if this is removed any any part of the 3-way handshake optimisation will not occur.
That apart I'm assuming you have configure and loaded the client software under the WX Client options, enabled adjacencies to be formed?
