Routing between Azure FortiGate-VM SSL-VPN

Hi, I have two single VM FortiGates in Azure.

Each FortiGate is in a different region.

They were both configured with the default three subnets within a vNet

I have peering between the local vNets and each local FortiGates vNet

So traffic between each regions vNets and the local FortiGate routes correctly.

The FortiGates also have a IPsec P2P to on-premise FortiGates and traffic also routes correctly.

What I'm trying to achieve is routing from either Azure FortiGates SSL-VPN to the other regions FortiGate and local vNets.

I have the SSL-VPN configured with its own subnet and all the required policies to allow the traffic.

I have setup peering between the two Azure FortiGates vNets and even set a UDR routing it to the remote FortiGates internal ip x.x.x.68

I've set these two options on the peering.

Allow 'Region1_FTG' to access 'Region2_FTG"
Allow 'Region1_FTG' to receive forwarded traffic from 'Region2_FTG'

Allow 'Region2_FTG' to access 'Region1_FTG"
Allow 'Region2_FTG' to receive forwarded traffic from 'Region1_FTG'

I have set a static route on each FortiGate to route the traffic for the remote network out of port2, but the traffic still goes nowhere.

I can see the test traffic hitting the SSL-VPN to LAN rule, but it goes no further.

Does anyone have any thoughts as to what I'm doing wrong?
