Sophos UTM Home no internet

Newb here trying to test out Sophos UTM Home, getting no internet connectivity.  Researched basic setup procedures with no luck.

*Running version 9.352 on a Shuttle box with 2 nics

For testing purposes, the flow is ISP cable modem->Sophos UTM->workstation

*eth0 getting public ISP address

*eth1 configured with internal lan address 

*One firewall rule: internal(network)->any->any

*One Masquerading rule: internal(network)->external

*DNS using forwarders by ISP, also added Google DNS servers

*Setup DHCP, workstation getting DHCP address correctly, able to ping eth1 and eth0 address.

*Unable to ping public ip address (i.e. 8.8.8.8) by either workstation on UTM box

*Firewall log only shows Default Drop from public external ip address to eth0 WAN interface

*Checked to make sure settings are enabled...not using other services (i.e. Intrusion, Web filter...etc)

Not sure what I'm missing, is there a return route that needs to be entered somewhere?

  • Sorry, I missed the line about the MASQ rule.

    Very odd that you can't make connections from the UTM itself. I take it that the ISP modem is bridged?

    "eth0 getting public ISP address" Via DHCP from the ISP I assume. Default GW checked for this "WAN" interface?

    Do DNS Lookups work from Support > Tools > DNS Lookup?

    On the Dashboard, does the WAN show UP for both link and state?
