  • How devcentral team knows your password?  please check with concern team

  • Hi davidy2001 , 
    this prompt doesn’t relate to F5 or virtual servers but your PC operating system (windows/MAC)  itself , 
    at the same time this usr is wrong "http:" how http and port 80 could exist in same line , 
    ( = ) I mean that.

    user PC access and got the below info. Is this Authentication Required from user PC or node or other?

    Do you ask what kind of node behind f5? it has two devices. One is router, other is win7.

    Using credential of router cannot resolve the issue. but

    After I disabled the router, that Authentication required box disapper. 

    You are right. the issue resolved. Thank you!

    I got below page. that is because this is win7 without page setting. but still feel weired one router as node cause such strange behavire

    • Hi davidy2001 , 
      Great news bro , I expected that behavior because of a device behind your F5 device. 

      > I want to say that accessing a routed behind F5 isn’t doable , Router is used to transfer traffic and only you can test " ping icmp " on it through F5. 

      > But if you published web server behind F5 you can access it with using F5 virtual server , and publishing web servers is the most widely deployed with F5 , But F5 does say no to any device behind it and can deal with any type of technologies.
