HTTP load balance round robin port is not accesable

Hi I created a simple load balancer with 3 HTTP servers and the port: 8080 is not at all accessable from browsers (Chrome/IE) , however the IP and port is responding from TELNET.

 

Any idea fro F5 BIG-IP should check.

    Hi There,

     

    Do you have a (sanitized) configuration example of how this is set up?

  • If I'm understanding your setup correctly, your virtual server can be listening at port 80 and load balance to pool members at port 8080. In other words, the port on the pool member does not have to be the same as the port on the virtual server.

     

  • @crodriguez: yes thats correct > my configuration just as you assumed. My load balancer pool members at port: 8080 (3 nodes and each node in the same port: 8080) and virtual server port: 80( i've also tried with 8080 on virtual port ) but no luck.

     

  • @dan: here is my virtual config

    ltm virtual dsodvs { description "DSoD Virtual Server LB" destination 10.48.154.80:http ip-protocol tcp mask 255.255.255.255 persist { source_addr { default yes } } pool DSLBPOOL profiles { tcp { } } source 0.0.0.0/0 translate-address enabled translate-port enabled vs-index 9

     

    }

    here is my pool config =---------------------- ltm pool DSLBPOOL { description "DSoD Virtual Server LB" members { mo-569b0147e.mo.sap.corp:webcache { fqdn { autopopulate enabled name mo-569b0147e.mo.sap.corp } state fqdn-up } mo-569b0147e.mo.sap.corp-10.173.91.47:webcache { address 10.173.91.47 ephemeral true session monitor-enabled state up fqdn { name mo-569b0147e.mo.sap.corp } } mo-c8fe96fa1.mo.sap.corp:webcache { fqdn { autopopulate enabled name mo-c8fe96fa1.mo.sap.corp } state fqdn-up } mo-c8fe96fa1.mo.sap.corp-10.173.89.56:webcache { address 10.173.89.56 ephemeral true session monitor-enabled state up fqdn { name mo-c8fe96fa1.mo.sap.corp } } mo-d8a756448.mo.sap.corp:webcache { fqdn { autopopulate enabled name mo-d8a756448.mo.sap.corp } state fqdn-up } mo-d8a756448.mo.sap.corp-10.173.91.128:webcache { address 10.173.91.128 ephemeral true session monitor-enabled state up fqdn { name mo-d8a756448.mo.sap.corp } } } monitor http

     

    }

    anything you want ?

     

  • You can try to add HTTP profile: http, and set Source Address Translation: Auto Map to your Virtual Server

      @quantiti: thank you, i made changes but it still not working. we found our internal proxy blocking the port from our NGAI (next generation internet access) which was the root cause finally we found and it worked after checking NGIA.
