I am replacing an Untangle installation with Sophos UTM 9.200 because the PC died and had to be replaced. I like the reporting and filtering of Sophos better. I bought a micro form factor PC (Acer Revo) and use the same USB to Ethernet adaptor I used on my old box. During installation, Sophos did not detect the second Ethernet port and brought up a warning screen that said with only one Ethernet port I could install and try the interface but that it would not function as a true UTM gateway. That made sense, and I figured at some point it would discover the USB-Ethernet adaptor and all would be made right again.
The rest of the setup went fine and it did discover the USB-Ethernet adaptor and I have 2 Interfaces in my control panel. However, because it did not find it during the initial wizard install, I think some settings someplace did not get set right (maybe Static Routes?) because NOTHING gets through the UTM to the Internet. I am getting email from Sophos to my yahoo mail, but I can't browse sites or ping or do anything. Tracert shows all traffic stops at the UTM.
I have attached a system diagram. It is pretty simple. I have my cable modem plugged in to the UTM port that is configured as External in Sophos. I get my IP and DNS settings dynamically from my ISP. The other Ethernet port of the Sophos is connect to a wireless router from Belkin. Between the two I have static IP addresses set up no both sides. I left the wireless side of my router unchanged.
I can connect to all wireless devices as before. I can get to the UTM web admin from a wireless device without an trouble. I just can't do anything on the internet. I thought it was a DNS problem at first but then I saw I had no static routes set up. I tried to set up a few static policy routes hoping something would work. I have attached a few screen shots of my configuration. I also have a screenshot of tracert.
I am not a networking guru, but I think I know enough if someone can point me to the right area. I think what I am missing is the detailed Sophos knowledge, and the product is so full featured I want to be sure I don't "over do it" with changing configurations.
Thank you for the help.
