I currently have a core system called RoutersA. On a broad view I have five routers(B) that all utilize IPSEC and Gif interfaces that tunnel into "A". This allows everyone to communicate with each other and it working fine. What I want to do is pass all traffic from routersB to A. Anything that is going outbound would have to pass through RoutersA, Web traffic, SSH traffic all of it.
I'm using PF and some NAT but I don't know if where to start with this! Any help would be appreciated as to where I should look to accomplish what I want to do.
Thanks
