I've got 4 site-to-site VPN tunnels to PIX 515E in my central office (A). From this office I can ping branch offices B, C and D. From offices B, C and D I can also ping my central office A. However, my problem is that I can't ping office C from office B or office D from office C so on.
He is the question: is there a way to configure vpn routing for packets to travel from office B to office C via central office A? I know I can configure a vpn link between B and C but it's not an ideal scenario for me.
