UTM SG 115 won't connect to Internet

I have a brand new Sophos SG 115 appliance

 

The WAN interface connects directly to my Comcast cable modem and gets a DHCP address (I do not have a static IP address from Comcast).

My SG 115 uses the Internal IP of 192.168.2.1

IP settings on my computer are:
IP:  192.168.2.1
Netmask:  255.255.255.0
Gateway:  192.168.2.1
DNS:  192.168.2.1

Looks pretty straight forward.  However, I cannot connect to the Internet.  I can't bring up any website, ping anything, FTP anywhere...nothing.  I've restarted everything.  I've reset the Sophos to factory default at least 3x's already.  If I setup my older Linksys router onto my Comcast modem, it connects fine and I have Internet.  Disconnect that and hook up the Sophos and nothing.  I don't know my way around well enough in the Sophos to see what address it's getting from the Comcast modem, but I suspect it's the 192.168.0.3 (since 192.168.0.1 should be the gateway to the Comcast modem).  What am I doing wrong here?  What's going on?  See the screenshots below for my settings, which look pretty straight forward.

  • Did you configure a masquerading rule under Network protection -> NAT -> Masq?

    This is needed to masquerade your internal IP range to the external IP.


    Managing several Sophos UTMs and Sophos XGs both at work and at some home locations, dedicated to continuously improve IT-security and feeling well helping others with their IT-security challenges.

    Sometimes I post some useful tips on my blog, see blog.pijnappels.eu/category/sophos/ for Sophos related posts.
