VPN

I have 5 monowall routers, A through E, each connected to the Internet, linking multiple branch locations.

Currently, each has an IPSec tunnel to each of the others to facilitate communications between each of the 5 sites.  To make for easier configuration when adding sites, I'd like to create a star setup, instead of a mesh, where B C D and E each have a tunnel only to A, but traffic can flow from B to C, via A.  I think I understand how to configure this sort of setup, but IPSec tunnels don't seem to be "interfaces" in the same way as a physical port is.

Any help is appreciated.

Due to limitations of IPsec in the underlying OS, I don't think this is possible.

In a star topology VPN runing IPsec Main mode, m0n0wall can act as the "center" site. I'm not sure if it can act as a "branch" site.

I did have such a setup where the "branch" sites are pfsense and other types of firmware.

Due to limitations of IPsec in the underlying OS, I don't think this is possible.

I currently have the same setup with site A being my collocation facility with all of our production computers in it.  Is it still the case that you cannot send traffic from B to C through A even with the latest updates to the m0n0wall software?
