Hello,
We have a Sophos UTM 220 device, which sits behind a Cisco ADSL2 router.
Now the router authenticates and creates the internet connection. I believe this has NAT running on it already.
Also the Sophos UTM 220 has NAT running on it. Should I disable NAT on the cisco router or or on the Sophos UTM? Where is it recommend to have NAT?
Bascailly this is the setup
