I am using UTM 9
I have an internal network 192.168.10.0/24, astaro internal address is at 192.168.10.1
the external address of the address is 67.108.x.y and is on a 67.108.x/27 network
I have a number of nat/firewall rules set, and the system is fine, except that from the 192 network, I cannot access any of the resources that are on the 67.108.x network. (for example, I cannot ping the 67.108 side of the astaro gateway from inside the 192 network). All other internet resources are accessible.
Is there a specific rule i need to set to make this work?
As a second question, can anyone recommend a good internet resource to help understand firewall configuration in general
