NethServer Version: 7
Can someone advise me how to enable a NAT exclusion on the Nethserver/Shorewall Firewall.
I have a private subnet on the LAN (Green) which seems to automatically get NAT to the RED interface. This is fine and allows the local LAN severs to get updates etc.
However, I have a need to not NAT when communicating with particular outside addresses. i.e.
LAN 192.168.1.0/24 PC’s get NAT out to Red Interface for example. But, if the destination is other private ranges (these are reachable beyond my RED zone) I want the source address of 192.168.1.0 to stay in place.
I am familar doing this with NAT rules and policy on Cisco, Juniper etc, but not on Nethserver.
Any pointers would be very much appreciated.
