VPN and Internet Access Conflict

Last Modified: 2010-04-12
Dear EE members,
I have a proxy server to control end-user internet access. Currently, we have implement a VPN where
it must link to an internet site 'A' to get email. By adding the HQ company 's DNS to point to 'A' , it also
enable the end-user to access internet.

I don't want the end-user to access internet by pointing to 'A'.
I want to point to 'A' and access 'A' only.

It is very confusing..

Any guideline?

If you have a proxy server, you should be able to control the access through it with rules or filters...  

What kind of proxy are you running?  Also, if I read this correctly, you did not have a local DNS server?   You only had a dns entry when you pointed the to hq's DNS?  


Dear EE member,
We have wingate proxy server in one machine and a cisco router to A. Where the cisco router is a firewall and vpn purpose.

Wingate Proxy can be configured with a Deny all  and then an exception for the 1 host you are trying to hit.  
Remove the dns settings so that your box will not hit A anymore.  THen use a hosts file instead with the single entry for A for resolution.  


Dear EE members,
If I add an entry to hosts file:
should I use local ip for A site,since it is VPN
use internet ip for A site.
If I use internet ip for A site, then the user not authorised for internet access cannot access A.
We have about 50 users in the office, should I manually go to each pc to amend their hosts file?
Any better way?
Any suggestion and futher explaination?
