point your default gateways to the main internet connection and NOT to the 
MPLS-Gateways.

NAT enabled.

 

But I am doing this already, all branch computers are sent to the internet 
server in the main office via the router on branch sites

 

to get the Net-to-Net (172.16.11.0/24 <http://172.16.11.0/24>  <-> 
172.16.0.0/21 <http://172.16.0.0/21> ) working:

just create a IPSEC VPN-Tunnel from each pfsense box to the other one

through the mpls routing/switching, which (the mpls) is not really necessary if 
you have static WAN-Addresses, but can help to have a stable vpn-tunnel.

i.e.

IF-MPLS-Address Main Site connects to IF-MPLS-Address-Branch site, et vice 
versa.

so an IPSEC-VPN between those two endpoints should do it.

the mpls gateways do not know anything about any 172.16.0.0 net. 

not their job. :8~)

 

i _think_ the wish is to have the clients communicating with each other like

172.16.4.5 can talk freely to 172.16.11.45 et vice versa.

 

so create each VPN-Side with the access to the certain internal network. no NAT 
necessary.

 

further reading for understanding recommended:

Richard W. Stevens TCP/IP and/or 

Addison Wesley: TCP/IP and ONC/NFS

 

Thank you any site to get me started with basic IPSEC VPN-Tunnel on pfSense ?

 

thanks
