You can create a router in each project and attach it to the specific external network (via gw) ... but:
* With the default policy, the tenant can create another router for the other network. Quick solution: change the policy to not allow creating routers * I think it will be confusing for the users, they will see 2 ip allocation pools, if they choose the wrong allocation pool, wont work. You could pre-allocate a set of floating IPs per project and then change the policy to not allow allocating more ips to the tenants ... (I haven't tried this!) * The users will see both external networks in the network topology (not a big deal, I think) ... More ideas?
