VPN hub and spoke question

I need two branch routers to be able to pass traffic to each other without a dedicated vpn tunnel between the two branches.


HQ LAN is 172.16.x.x and 172.17.x.x

Branch Routers use 192.168.x.x


***PIX***



access-list nonat permit ip 172.16.0.0 255.255.0.0 192.168.48.0 255.255.255.0
access-list nonat permit ip 172.17.0.0 255.255.0.0 192.168.48.0 255.255.255.0

access-list mtl01rt01ec permit ip 172.16.0.0 255.255.0.0 192.168.48.0 255.255.255.0
access-list mtl01rt01ec permit ip 172.17.0.0 255.255.0.0 192.168.48.0 255.255.255.0

route outside 192.168.48.0 255.255.255.0 "Internet Router"
