VPN Group Gateway

[veriqster]

Hi,
I'm trying to set up a VPN gateway group and I created 3 VPN clients that have been designated as interfaces and then as gateways. I also managed to create the Gateway Group, however, when I try to designate the gateway group as the outbound gateway for the firewall rules I cannot select it - it is not showing up in the drop down menu.
So far I have:
3 OpenVPN Clients, all designated as interfaces.
3 gateways coresponding to the bove interfaces
1 Gateway Group that joins the 3 interfaces as tier 1.
Outbound NAT rules for each of the VPN client interfaces.
THe NAT rules are set to "Auto + Manual"
Am I missing some configuration step or is it a software glitch.

I have an identical setup with pfsense and that works just fine, reason for moving to open sense is the attitude displayed by some of the PfSense developers on public forums and, mor eimportantly the fact that OPNSense seems to have better (more up to date) support for non Intel NICs.

Thank You!
