L2L tunnel with NAT

[piacas]

I have a need to NAT outbound traffic to a specific Range if the traffic needs to go across a L2L tunnel. Remote customer gave us a range, so traffic going to them is 'seen' as from that range. 

I have the L2L tunnel up, how do I make the fortigate nat the traffic?

Thx

Define an 'IP pool' with the NAT range and in the policy 'lan' -> 'tunnel', enable NAT. Specify 'from pool' and select the pool. Source addresses will be NATted then.

If the pool is large enough (i.e. /24) you'll get a 1:1 mapping. If the pool is smaller, addresses will be reused.
