Hey,
I've been experimenting with the Sophos XG Home Firewall and FlexiWAN at home to get a better grasp on these technologies.
I'm currently busy with the Sophos XG FW and want to set it up with the WAN being the external NIC and the LAN an internal NIC.
Since I'm at my own home I have a 10.0.0.0/16 IP range configured, everything at 10.0.0.0/16 is DHCP, 10.0.1.0/16 is reserved IP addresses and I want 10.0.2.0/16 to be my LAB. Currently they are /16's and can
communicate with everything but I plan to make my LAB fully isolated at a later stage. Normally I would do it first but for me the priority lies now in getting the SDWAN's / FW's up and running.
I have installed Sophos XG FW on a VM with 2 NIC's
- WAN = External = 10.0.1.245
- LAN = Internal = 10.0.2.245
However, whenever I run through the installation of the Sophos the LAN cannot communicate with the gateway = 10.0.0.1
This makes me believe that the internal NIC cant communicate with the external NIC, is that correct?
Or is it that it could be that NAT is not yet working on the Sophos and this is normal behavior?
