route b needs a route
0.0.0.0/0 gateway 172.16.16.10

Do you realize that default route should be found at the host in broadcast domain?

can you ping 8.8.8.8 from route b?
if you can ,route set is ok
if not ,may be dns is not set correctly

Nope, the ping says destination net unreachable, but nslookup works fine

i update the configuration, i missed up some details that now are in the original post.

Anyway on router B add a masquerade without specifing the interface.

Scrnat -> Masquerade
