Web Server Load Balancing

I've a BIG IP LTM device which I need to configure for load balancing web servers. I've created both nodes, added them to a pool and added the pool to the virtual server. But I'm unable to ping or http to the virtual server. Can anyone please find me a fix for this issue. Or if I'm missing any steps please let me know. This is kind of a headache for me now. Thank you

    Do you have an ICMP monitor on the node and/or pool members? If so and it's green that would prove the ADC can ping the servers.

     

    BTW, you're not talking about pinging the servers through the VIP, are you? That would fail unless you provision a VIP for that.

    Hi

     

    Just quick check before anything else. You didn't forget to enable SNAT or Automap by any chance ?

     

    Your POOL status is green ? and the VS status also ?

     

    And if this is all OK, can you do a tcpdump on the F5 while trying to access the virtual server

     

    tcpdump -i any host
