First Time setting up F5

Hi all, this is my first time setting up F5 VE from scratch which was different from managing one which is already setup.

 

I have both application server up & running and both server's firewall is disable. The F5 external IP and the server's IP are on the same subnet and no firewall in between.

 

1) It seems F5 is able to reach port 5005 and 80 but not 15005. I check back on both servers and port 15005 is in "Listening" state

 

Ltm::Node: 10.1.1.1 (10.1.1.1)

State : enabled

 

Reason : Node address is available

 

Monitor : /Common/icmp (default node monitor)

 

Monitor Status : up

    Doran,

     

    What type of Monitor is QA_15005? Is it just a tcp one?

     

    The best suggestion would be to run tcpdump on the f5 to see if this gives you any clues, are you seeing the return traffic, for example. I'd also confirm the settings in the monitor too.

     

    Hope this helps.

    I'm really sorry it's my fault.. I was confused about the whole F5 structure, I thought the Pool are the ones that's facing the Public and VS will be the one reaching the application server.

     

    I understand now that I should create a new VS with a new Virtual IP. Then it should be link up to the Pool which will load balance to the Application Server.

     

    I realise I went to create Virtual Server with the same IP of the application server which is why I'm able to ping it from ssh.

     

    Now I realize there's another issue, the F5 VE cannot reach any application server or any other server. where should I start the troubleshooting ?
