Multisite routing

[tdkaps]

Hi, I tried posting this under Ipsec. I´m hoping for greater luck under this subject.

I have multible ipsectunnels configured from a my main pfsense router.
I have no problem getting data through to and from the main router and the routers on the other sites.
I cannot get traffic from one external site to another.
The external VPN routers are from draytek, and I have entered a static route to the other external sites on each of the external routers.
I have made a firewall rule to allow everything on Ipsec.

I would suspect the solution being somewhere in the routing of the main pfsense router.

So my setup is:        External(Draytek)  <-> Mainsite(pfsense) <-> External(Draytek)

Thank you in advance
