VPN Users can't connect to remote network

[eslamelmasri]

Hello,

We've been experiencing a problem with VPN connection

We've 2 buildings, Building A has ip range 10.10.108.0/22, and Building B 10.10.116.0/22

And Building A has Fortigate 200D, Building B has Fortigate 200E

When we use forticlient vpn and connect users to Building A, They cannot reach Building B also users connected to Building B cannot reach Building A

Any ideas? 

Thanks in advance

Many conversation exist for the situation in this forum. And it depends on how you have set up SSL VPN at both FGTs, including NAT or no NAT. If NATed, it uses the tunnel interface IP as the source IP if configured. If no NAT, the question is the routing between the client IP pool subnet and the destination subnet on the other side of the tunnel, which you need to check both are possible to reach each others routing-wise as well as policy/phase2 selectors on the IPSec VPN.
