Hi Matt,

Yes I've tried defining the network as 'Tunnel All', allow 192.168.1.0/255.255.255.0 and allow 192.168.0.0/255.255.0.0 individually and none work for our primary Fortigate.

Interestingly all of the above work fine for our secondary Fortigate - please see my previous postings for the make/model/firmware of our primary/secondary Fortigates.

Can you think of anything that might be configured differently on our Primary Fortigate that would always cause a 'No DHCP Response from Gateway' on Shrew everytime when the local subnet of the connecting client is 192.168.1.xxx?

Many thanks again,

Ben Chamberlain

Ben,

Do you have the 192.168.1.0/24 network defined in one of your policies?
