Hello,
I have TMG 2010 deployed in a remote site to serve as an Internet Proxy. In that remote site, there's a WS 2008 domain controler and a machine running WS 2008 and hosting ForeFront TMG 2010.
In the past few days, the configuration of the TMG machine has been changed, that made it as an open gateway to internet... Users even with no configuration of Internet Proxy, with no permissions... are able to connect to internet.
About firewall rules, there's a rule for every user that gives him access to Internet from just one IP address.
The default rule, "Allow all users to access Internet" is deleted by default, during the deployement of TMG.
The configuration of the Web Access policy are:
- Proxy web: activated (port : XX)
- authentication: proxy authentication
- HTTP compression: deactivated
- Web cache: activated
- Malware inspection: deactivated
- HTTPS inspection: deactivated
Any help, would so welcomed and thanks in advance for your help.
Regards
