Many to Many NAT rule

David Fox

I have a UTM running 9.4xx  and need to perform many to many NAT. I am new to Sophos appliances but am familiar with others where this is possible.

Is this a limitation of Sophos UTM?

    You can only use 1:1 NAT for this (or create separate NAT-rules for every individual host).

    1:1 NAT is like many-to-many but it must use CIDR network range, so it's possible to 1:1 a /29 network to another /29 network, but it's not possible to NAT ie. x.y.z.7 - x.y.z-13 to another range.

    Managing several Sophos UTMs and Sophos XGs both at work and at some home locations, dedicated to continuously improve IT-security and feeling well helping others with their IT-security challenges.

    Sometimes I post some useful tips on my blog, see blog.pijnappels.eu/category/sophos/ for Sophos related posts.
