[Users] Routing to NATed gateways

Hi Leonid,

the scenario you are probing might be already doable. Set in the LCR 
table some IP addresses which will be used as aliases: private addresses 
in 10.10.x.x class for example. Then register this IPs in usrloc 
pointing to the real GWs address.
So you can do lcr (next_gw) and then lookup.

for this to work, lcr must operate on RURI and not on DST_URI (not sure 
how exactly is working).
