Dear Team,

 

 

My network is as follows

 

 

In my scenario , servers and vip resides in same network . Default gateway of servers are Core switch .

 

Following is I have done

 

1) Created a internal VLAN ( etherchanneled)

 

2) Created SelfIP- Non floating ( 172.16.4.40)

 

3) Created SelfIP - Floating (172.16.4.43)

 

4) Created VIP - 172.16.4.45

 

default gateway of F5 is 172.16.4.1 ( core switch which is the default gateway of servers too)

 

 

I have created SNAT ( autonat) on the VIP .

 

 

issue what i am facing is when i access the real IPs 172.16.4.31 and 172.16.4.36 on port 8006 portal works with out any issues . Nevertheless when i access it through 172.16.4.45 which is VIP , clients are not getting any response ( getting as connection interrupted)

 

I have no clue why even after SNAT this issue is happening. i have target of finishing this task tomorrow and still i am no where in resolving this.

 

 

Can somebody help me out in this?

 

 

thanks a ton in advance

 

 

Paddy

have you captured traffic on bigip to see what is going on?

 

 

e.g.

 

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

 

x.x.x.x is virtual server ip

 

y.y.y.y is pool member ip

 

z.z.z.z is another pool member ip
