RE: Finding out IP address of external interface of web proxy

["Edward Ling" <e.ling () wessexarch co uk>]

Hi Devj,

If I understand you correctly, the user is sat at a machine on the
internal LAN with an internal IP address of say 192.168.1.x and wants to
find out what the external IP address is? 

This should be fairly simple as all they'd need to do would be to browse
to http://whatismyip.com/ which will report the external IP address in
the web browser.

Is there any particular reason why you don't want a user to know the ex
IP?

Subject: Finding out IP address of external interface of web proxy

Hello All


How do I find out the IP address of the external interface of my web
proxy?

To explain a bit further: A user browses web sitting in a LAN through
the web proxy that allows HTTP. The web proxy is connected to the LAN
using one interface and it is connected to the outer network using
another interface. Can the user find out the IP address of the outer
interface? If yes, how?


Thanks in advance for any replies.
