3 fortinter boxes - need to route traffic from fotinet box #2 to box #3 through box #1

[jamestiberius]

I have 3 fortinet boxes.

box 1 is 600c at main office

box 2 to is 90d , connects to  main office via MPLS

box 3 is 60c, connects to main office via IPSEC tunnel

I need box 2 and 3 to be able to talk to each other.

I have tried putting a router from box 2 to box 3 on box 2, and vice versa, but still not routing traffic.

is that all that would be needed to make this work, or am I missing a step?

I'll assume the following:

Box 1 has a route to the Box 2 subnet via the MPLS router

Box 1 has a route to the Box 3 subnet via the IPSec tunnel

What you will also need:

-policy on Box 2 to allow outbound traffic to the Box 3 subnet via the MPLS link (you need this in addition to the route)

-policy on Box 2 to allow inbound traffic from the Box 3 subnet via the MPLS link

-policy on Box 3 to allow outbound traffic to the Box 2 subnet via the IPSec tunnel (you need this in addition to the route)

-policy on Box 3 to allow inbound traffic from the Box 2 subnet via the IPSec tunnel

-policy on Box 1 to allow traffic from the interface off of which the MPLS router sits sourced from the Box 2 subnet to the IPSec tunnel

-policy on Box 1 to allow traffic from the IPSec tunnel to the interface off of which the MPLS router sits
