Hi there. Newbie here. I don't get it.
I have two ip ranges in my network 10.0.0.0/24 and 192.168.1.0/24
I've setup the XG210 with the 192.168.1.0 range as LAN and everything works fine except I can't reach the 10.0.0.0 range from 192.168.1.0 range.
How can I remedy this ?
Thanks, Marc
My knowledge of doing this with an XG is limited but in the absence of any other responses I will add these comments and suggestions.
Static route would not work. If the XG doesn't have an IP in the 10.0.0.0 subnet, there is not way for it to discover hosts and know how to route the traffic.
What you are trying to do with the IP alias, is hairpin traffic - traffic going in and then back out of the same interface. Have a search for hairpin NAT in the XG section and you may be able to get this to work. I've set one up but it isn't the easiest of things to do if you don't have a good understanding of networking.
What I don't understand from the details you have supplied is why you don't just setup a new LAN interface on the XG with a 10.0.0.0/24 address. This would be much simpler and a lot easier to manage traffic between the two subnets going forward.
Hi Marc, Thanks for reaching out to Sophos Community.
If the network range 10.0.0.0/24 isn’t configured on any of the firewall interfaces then you can add a static route 
But it's recommended to configure the same network on an Alias IP and add a LAN to LAN rule to allow communication between these hosts.
Also, there's a possibility if the Gateway isn’t defined for 10.0.0.0/24 network then the traffic might not even hit XG and would rather be routed through the defined gateway.
