accesslog shows IP Addresses not authenticated

We are using authentication against our active directory then anyone can´t surf in the internet without authentication, the problem is as follow:

I'm seeing the acccess logs and I can see normal logins, something like this: (username, internal address, etc , etc)

Re: accesslog shows IP Addresses not authenticated

Does your firewall allow internet access in to the proxy port(s) of your Web Gateway?  That would be the most likely answer.

Re: accesslog shows IP Addresses not authenticated

Looks like you SSL rules placed BEFORE authentification rules (or SSL rules is absent).

Re: accesslog shows IP Addresses not authenticated

Hello,

can you please provide details about

- MWG version used?

- Deployment (Direct Proxy, Transparent, ...)?

- SSL Scanner on/off?

Best,

Andre

Re: accesslog shows IP Addresses not authenticated

The version of MWG is 7.2.0.8.0 (14873)  and is deployed in Transparent Bridge Mode, the SSL Scanner rule is disabled.

Re: accesslog shows IP Addresses not authenticated

Hello,

I think by default MWG won't perform authentication if SSL Scanner is turned off. If you got the authentication rules from the library you should see that there is an exclusion for "CONNECT" requests. Since MWG cannot look into the encrypted connections MWG cannot perform cookie authentication for those requests, since the cookies are provided within the encrypted connection.

This could be a reason why the CONNECT requests won't be authenticated in your setup.

Best,

Andre
