If you NAT outgoing traffic then source zone is INSIDE and destination zone is OUTSIDE.
If you NAT incoming traffic then source zone is OUTSIDE and destination zone is OUTSIDE.
If you NAT traffic where sessions are initiated from your side towards tunnel then source zone is INSIDE and destination zone is L2VPN.
If you NAT traffic where sessions are initiated from other side of the tunnel towards you then source zone is L2VPN and destination zone is INSIDE (in most cases unless you change destination IP. In this case you might need destination zone to be OUTSIDE if pre-nat IP is not in your routing table).
