ASG220 8.306 - Bridging and Vlans Issue

ASG220 sits between internal network and cisco pix.

Eth0 and 1 Bridged, users are pulled from AD, Webfiltering and profiles are configured for Transparent mode with Browser authentication.

When you go to browse you get the browser prompt for login details and the proxy profiles seem to be working fine.
 
Until you change the bridge from standard to Vlan then it all falls apart [:(] users now have full browsing access with no prompt for details.

Pulling my hair out (whats left of it) , where am i going wrong ?

Regards
Stu

  • I think you've discovered the problem with transparent on the bridge - good job of creative problem solving!  I've not run into that bug before.  I don't think there's any point in using tcpdump.

    You might want to revisit the decision about AD.  Check out Configuring HTTP/S Proxy Access with AD-SSO
