Hello,
You need to add the remote network(s) to the "Remote subnet" list, and/or the local network to the "Local subnet" list:
netA -- RUT-A <===> RUT-B -- netB
Put netB in the Remote subnet list of RUT-A and netA in the Local subnet list of RUT-B
Put netA in the Remote subnet list of RUT-B and netB in the Local subnet list of RUT-B
Regards,
