Dmitry,

Do you say on auth-proxy router with 'no ip http server' still you can
invoke the authentication prompt?

My test is following:
'ip http server' -> auth-proxy window invoked
'no ip http server' -> auth-proxy window not invoked

Could you clarify this?

P.S. from IOS 12.3(1) auth-proxy can be used via telnet and ftp as well.

Regards,

Vilmos

What is the proper way to configure auth-proxy ?
Here said:
http://www.cisco.com/univercd/cc/td/doc/product/software/ios121/121cgcr/secu
r_c/scprt3/scdauthp.htm#1001219
that "Configuring the HTTP Server is required task"
However It looks like it's not necessary at all.

Whenever I open browser from within inside with some
http://IP-routed-behind-the-router-with-auth-proxy-configured,
I always get proper auth-proxy login prompt (assuming that I configured
auth-proxy itself) doesn't matter if I have http server enabled or not.

If I open browser with http://ip-of-auth-proxy-router I get either "The page
cannot be displayed" or, if I have "ip http server" enabled,
I get "Cisco level 15 prompt"
So what is the point (if any) to configure http server on the router where
auth-proxy is enabled ??

Thanks,
