I recently stumbled on this KB article (118975) and noticed a small bug on the network diagrams of each scenario:
N:M connection with overlapping subnets
N:N internet connection
In both cases, local site should have the IP Range (192.168.10.xxx) and the Remote Network (192.168.10.xxx). Unfortunatelly the network diagrams for the remote sites shows the IP range of the local site: 192.168.10.xxx, creating a bit of confusion.
It would be nice if someone could fix this.
Did you go to the bottom of the KB and point it out under comments, that is were Sophos asks for errors.
Thanks for submitting this. I'll forward it to the team for their review.
