Require username and password for virtual server

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:10.0.30.100:80" how http and port 80 could exist in same line , 
(http://10.0.30.100 = 10.0.30.80:80 ) I mean that. 

> Does this window appear during accessing the virtual server from a browser or what ? 

Regards. 

Mohamed_Ahmed_Kansoh Thanks. The topology is like this:

user PC -----(10.0.30.100)F5(10.0.20.254)-----node(10.0.20.2)

> Does this window appear during accessing the virtual server from a browser or what ? Yes

user PC access 10.0.30.100 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
