I didn't look at the dump, but will take your interpretation 
of it. Is it possible for you to have problems with the 
reduced MTU of the ipsec packets. Can you fetch a small web 
page from the realserver, or run a service with small 
packets, eg telnet? If you haven't handled that already, 
lookup the sections in the HOWTO that have MTU in the 
section heading.
