How to configure UTM Sophos firewall as a proxy server? (Part1 Install)

Sophos UTM is easy to install.
I asked for ISO to Sophos website
2 Virtual Machine: 4 CPU, RAM 4Gb, HDD 20 Gb,  5 Ethernet adapter (User, Managment, ISP1, ISP2, Cluster Replication)
Now choose the IP address for each network

I'll try to guess the management ethernet :)

Set IP for managment network

  Now go to the virtual machine console (e.g. VMWare) and verify (ifconfig) that the "Virtual machine mac-address" = "Console mac-address".  If you have not guessed the management network, you need to determine adapter and change the network in a virtual environment.

  Now add the route to the local network (eth1 = managment network):

001	route add -net 172.16.0.0 netmask 255.240.0.0 gw 172.16.52.1 eth1

  Now we are ready to open the web-management console (https://ip:4444)
