Log all traffic to specific networks

Hi Chris,

Good day and Thanks for reachong out to Sophos Community and hope you are well. 

For number 1:

-Web Proxy Live logs can be viewed in Web Protection > Web Filtering > Live Log

- For HTTPS FW rules, Make sure your FW rules for have the Log Traffic Checked:

-Logging and Reporting (Historical) can also be reviewed under: https://docs.sophos.com/nsg/sophos-utm/utm/9.708/help/en-us/Content/utm/utmAdminGuide/LoggingAndReporting.htm

-For SSH Live logs, you can view under System settings > Shell Access > Live Logs and for CLI/Shell it is under sshd.log

For Number 2: 

Authentication:

- You may try for the use case for Authentication only those who logged in with specified credentials will be able to access web: https://docs.sophos.com/nsg/sophos-utm/utm/9.708/help/en-us/Content/utm/utmAdminGuide/WebProtWebFilteringGlobal.htm

DHCP and BYOD features:

-Lease details available if you will be using UTM as DHCP: 

-I may recommend Sophos Mobile for a more comprehensive solution for BYOD use case: https://www.sophos.com/en-us/products/mobile-control it supports OS, Android, Windows, macOS. You may contact and reach out to your local partner/ local AM or SE for more details on this

Hope this helps. Have a nice day and thank you for choosing Sophos

Hi Raphael,

I enabled "WebProxy - Log only-mode" for https. Unfortunately that broke routing for some target hosts through IPSEC LAN tunnel. The proxy grabs all the traffic before any routing or NATing rule can be applied. Is there any solution for that? Whitelisting these targets does not help.

And: I was not looking for logging SSH access to the UTM itself but for ssh through the UTM to costumer sites. I do not need to know what the client does there I just have to notice that there was an access to.

Thanks & cheers - Chris 

Hello Chris,

Good day and hope you are well.

May you share screenshot of the said configuration? "WebProxy - Log only-mode" Thanks

For logs of SSH through UTM to Cx sites, you need to configure a Firewall Rule from *Designated network->Customer IPs& using SSH Service (Port22) then check the log firewall traffic on the firewall rule.

Hi Raphael,

sorry for my delay.

I misspelled the Webproxy: It is "URL filtering only" mode under WebProtection => Webfilter=>"https"

When I switch on this option I can see https traffic in webfilter logfile. But unfortunately now the https traffic for some costumer sites that are only reachable via IPSEC tunnel is broken.

I guess the webproxy grabs that traffic and does not reroute it through the necessary tunnel.

Is there any solution how I can route traffic after passing webfilter? Right now I have to disable that option therefore....

Thanks - Chris

Hello Chris,

Good day and hope you are well.

For your mentioned use case in Web Filtering you need to put the LAN network of the Branch office on the Web Filtering "Allowed Networks" on the SG device (Probably the Main/Head office where you would to use HTTPS proxy

Then on the VPN settings of Main office > Local Networks create and use network objects of the Branch then vice versa, Branch should be configured to have Network definitions and Internet of (Head Office) to it's remote networks.

Hope this helps. Have a nice day and thank you for choosing Sophos

Hi Rapha,

tank you for your answer.

But it is not a branch. We have IPSEC tunnels to different costumers. They work as expected - until I switch on webfilter for https.

And unfortunately adding the costumer target network(s) to allowed networks on webfilter global policies does not help to route the https traffic from LAN to costumer sites via the tunnel again. Clients will end up in a tie out and I have to switch off https filtering as soon as I can.

Cheers - Chris
