How to Check reverse traffic is leaving correct path from VE LTM

Hi, I am new to F5 and preparing for 1st certificate.

 

I have build a F5 BIG-IP VE LAB and configured web servers, pool, nodes and virtual ip. If i connect a web server from external network then i can see pool statistics shows IN packet count 10 and goes increasing but shows OUT packet count as '0' Zero. I have external default route pointed to external router.

 

Please help me how to check reverse traffic from LRM

    What result you are getting while accessing from external network? Please take the tcpdump and seeing whether are you seeing the return traffic.

    Hi Keshav, I was able to establish TCP connection on port 80 but soon it was getting reset (RST flag), it was due to internal routing issue same is identified using tcpdump and its resolved.

     

    thanks for quick help.
