using a VPN concentrator to mediate openvpn between clients

[mephisto]

Hey guys,

I'm trying to get a setup where I use pfsense on premises across a few of my branches connecting to a pfsense in a datacentre that works as a hub where all customers pfsense devices connect to. Basically office>datacentre>customers. My idea with this was to centralise traffic management instead of having tunnels from each of my branches directly to each of my customers.

The setup itself works but I'm having issues where every couple of minutes any open session like Microsoft RDP to a server freezes for about 15 seconds and then comes back. Ping keeps responding, but the connection for RDP and others for example freezes, then comes back. I guess there is a session that ends on one of the firewalls without the other firewall acknowledging it and the connection freezes.

I'm wondering if there is anything I can do to get this setup working?

I've tried to set up firewall optimization options to conservative to keep idle connections open in hopes it would help, but it doesn't
