I just started to use the Sophos UTM for my home network.
First I will explain my environment, so you have some background information.
I have a single server at my home, which is running ESXi 5.1.0, 1743533. This server contains 3 network cards, each for a single virtual network.
NIC0 my WAN connection
NIC1 my LAN1 connection
NIC2 my LAN2 connection
With my previous firewall, pfSense, both LAN NIC's where configured as a bridge. So I could use them both for my single lan network. All the 3 networks have the promisicuous mode set to accept, within the vSwitch configuration.
This worked fine with pfSense.
Sophos UTM is running inside a virtual machine on this server and is connected with all of the 3 networks.
This setup worked fine with the use of a single LANx network:
ETH0 is connected to LAN1 with a static IP of x.x.1.254
ETH1 is connected to WAN with a dynamic IP
ETH2 is connected to LAN2 not configured
At the moment I make a bridge between ETH0 and ETH2 inside Sophos UTM, I'm not be able to access some webpages inside my home network (running on different VM's), also the vSphere client isn't be able to connect to the server. But access to the internet from LAN1 and LAN2 is working fine.
I first thought that the firewall was blocking the traffic, so I created a new firewall rule for any (source) any (service) any (destination), but this didn't solve the issue. The traffic to these VM's shouldn't need to pass trough the bridge, so it would be strange if this was the solution.
When I disable the bridge, everything is working fine again. (except the LAN2 connection).
Do I missed some configuration settings of the Sophos UTM to make the bridge working fine? Please ask me if you need more information about my current setup.
Sorry for some grammar mistakes in this post, but English isn't my native language.
