VIP fails Telnet but responds to ICMP

Virtual server config is as below..

 

 

virtual vs_80 { translate address disable translate service disable pool pool80 destination 10.45.2.10:www ip protocol tcp persist persist80 profiles fastl4_80 {} vlans 80 enable }

 

 

VIP is - 10.42.2.10

 

 

pool member is - 10.45.2.20, Gwy - 10.45.2.129 ( L3 interface in same vlan on upstream router )

 

 

as telnet to pool member is not responding on port 80, i tried to use below tcpdump syntax referring to Aaron's link

 

 

tcpdump -nni 0.0 -X -s0 host 10.45.2.20 and port 80 and host 10.45.2.5 (self ip )

 

 

to determine if the pool member is responding on port 80...but it ain't ..as there is NO reply coming from the pool member.

 

 

So, i think, we are seeing correct packet.

 

 

Can you tell me ...where the mistake is....tcpdump syntax or the vaules i'm using.

 

 

As i said..this is indeed npath configuration....and a similar configuration is working on another device.
