I recently setup Sophos UTM 9 on ESXi 5.5 with two Physical network interfaces(Internal & WAN) and this is working well. However, a newly created DMZ(VLAN 200 tagged-ESXi Virtual Switch) interface attached to the UTM's DMZ Interface(VLAN 200 tagged in UTM) is causing problems.
As soon as the UTM's DMZ interface is turned on all traffic from the UTM internal interface to the UTM WAN interface is blocked.
I tried adding a DNAT rule in this thread but it hasn't helped me.
I realize that one is for internal to internal or the DMZ but I have not found one referencing my specific problem. Any help would be greatly appreciated.
