Hello everyone,
My Setup:
Fortigate connected via IPsec to my main customer. (external Ip x.x.x.1 / Internal 192.168.100.0 / Customer Network 192.168.10.0)
Microtik rb2011 my default gateway for internet. external IP x.x.x.2 / Internal 192.168.11.0
At the moment i switch between my the 2 eth ports on my mac, if i need the one or the other.
its a bit senseless 
My wish is to connect the lan port of the fortigate to the MT and route all traffic to the customers subnet (192.16.10.0)
through the MT to the fortigate and alle incoming traffic from the fortigate to my internal 192.168.11.0 lan.
suggestions?
thx
ra.ma.
