i understand what you are describing is how tcp profile works i.e. full proxy architecture.

 

 

sol8082: Overview of TCP connection set-up for BIG-IP LTM virtual server types

 

http://support.f5.com/kb/en-us/solutions/public/8000/000/sol8082.html

 

 

i do not think so far there is a way to change tcp to fastl4 profile in irule. not sure if we create two virtual servers; one uses tcp profile and the other one uses fastl4 profile, and then when active members is less than 1, send traffic to the fastl4 virtual server is workable.

 

 

anyway, i think tcp profile should also work. it could have something we missed. may you run this tcpdump command and have a look one more time? or can you upload the tcpdump file here or open a support ticket to get support guy to take a look?

 

 

tcpdump -nni 0.0:nnn -s0 -w /var/tmp/output.pcap host x.x.x.x

 

x.x.x.x is client ip address
