Wireless - Sign into XXX?

Just wondering whether anybody has had this issue before?

Users are on X LAN that use AD authentication for web filtering. I've no doubt that they probably lock their pc and go to meetings etc

They have an android phone and log onto the same network via radius. Almost immediately after authenticating, a pop up page appears asking them to login and our Sophos block page shows.

Now if I disable their mobile data and just have the wireless enabled on the phone, there is no issue. Having both enabled at the same time results in this issue.

Naturally we want both enabled so the user can use mobile data when outside the wireless network.

  • I don't understand how they authenticate into the wireless network with mobile data, Louis.

  • Hi Bob,

    they are authenticated via M$ radius using PEAP. Not using Sophos for wireless here. Strnage thing is, it throws up a login page "Please sign into <SSID>" but there are no captive portals etc and it's definately the Sophos UTM page that is showing up. To be honest, I've not looked into it too deeply ie examined the logs etc as it happens but was just putting out the feelers to see if anybody else had experienced this.

  • Very, very strange. Looked at log today:

    2018:03:26-10:55:58 gw01-2 httpproxy[6357]: id="0002" severity="info" sys="SecureWeb" sub="http" name="web request blocked" action="block" method="GET" srcip="10.2.12.106" dstip="" user="USERXXX" group="" ad_domain="DOMAINXXX" statuscode="403" cached="0" profile="REF_HttProContaInterLan2 (XXXX LAN 2 Filter Profile)" filteraction=" ()" size="2498" request="0xcac74000" url="http://gw01/favicon.ico" referer="gw01/auth error="Forbidden" authtime="0" dnstime="0" cattime="0" avscantime="0" fullreqtime="435355" device="5" auth="2" ua="Mozilla/5.0 (Linux; Android 8.0.0; Build/OPR1.170623.032; wv) AppleWebKit/537.36 (KHTML, like Gecko) Version/4.0 Chrome/65.0.3325.109 Mobile Safari/537.36" exceptions=""

    USERXXX was my phone (10.1.12.106) but I'm not that user (this is another user on the same domain). Cleared the cache/data etc on the phone. Forgot the connection etc but for some reason, my phone keeps registering as that user???

  • It sounds like this is a problem between your wireless and your M$ server, Louis.  I don't think there's anything to do in the UTM other than to confirm that wireless auth is screwed up somehow.

    Cheers - Bob
