Strange: Stalled TCP connection "SYN_RCVD" at Edge Server V2.0 on AIX

Hi:

My AIX Edge Server 2.0 is behind a firewall (By a NAT gateway, The gateway
is a Win2k server with "WinRoute" installed.)

The problem is I can access the edge server (working as a reverse proxy)
successfully in the intranet, but if I access it(web browser) throught the
NAT firewall with port mapping, the edge server will not response
occasionally (probability = 50%).

I listed all network connection by "netstat -an", and found a dead TCP
connection which is marked as "SYN_RCVD" each time the error occurs. After
several mintues the connection disappears and I can connect to it, but after
some time I can not access again, so back and forth..

Is there anyone who knows the solution?? Is this a bug ??
