Unable to ping to external site via gateway

Hello,

What could I be doing wrong here?

We have just been setup with a new MPLS service for our remote sites... the configuration looks like the attachment:

I have configured a static route like so:

10.100.50.x Gateway Route
========
Network: 10.100.50.0/24
Gateway: 10.100.55.6

This current configuration lets me I have I am able to ping and connect to the router in the MPLS network (i.e. 10.100.50.101) - which is great...

However I am not able to connect / ping to it via the local connection (192.168.22.1 (LAN)).
I have configured another Gateway route like this:

192.168.22.x Gateway Route
========
Network: 192.168.22.0/24
Gateway: 10.100.55.6

From the remote site, I am able to ping the HQ LAN 192.168.16.1 network etc.... but not from the HQ network I'm not able to ping / connect to the 192.168.22.1 router as I would have expected

Can anyone please advise how I'm to connect to the 192.168.x.x remote (as a 192.168.22.x network) network successfully? - It must be some kind of SNAT / firewall config... but I really can't figure it out with the routing...

Thanks,
Grant
