Cannot connect to Big-IP!!!!!!!!!!!!

Okay, I am brand new to all of this but I need some serious help.

 

 

Have two machines on my network that I need to connect to my HTTP VIP. Machine 1 connects just fine and machine 2 is unable to. Specifically:

 

 

* Machine 1 & 2 can ping the VIP.

 

* Machine 1 & 2 can tracert to the VIP.

 

* On Machine 1 I can open a browser and connect successfully to VIP but it does not work on machine2.

 

 

Are there settings in the F5 that are only allowing one machine to connect?

 

 

I did check the following:

 

* Nothing in my firewall is blocking the connection

 

* Both machines are currently setup with full admin rights

 

* my VIP is allowing all VLANs to connect

 

* one connect profile is set to none

 

* Connection Limit = 0

 

 

How can I turn on logging to see what IPs are connecting or erroring out?

    Looks to me like a product specific issue to me. We are here to help out with programming questions and are not really equipped to handle product related specifics. Your best bet would be to contact Product Technical Support.

     

     

    With that said, there should be nothing that's blocking inbound requests from different clients if they are coming across the same network. Simple debugging on your part could include

     

     

    1. running tcpdump on the BIG-IP.

     

    2. Writing an iRule and attaching that to the virtual that logs requests (to make sure it's making it from a networking perspective to your virtual).

     

    3. Try connecting to the management interface from both clients (this will test connectivity in general).

     

     

    I'm sure there are other things that support will guide you on...

     

     

    Good luck!
