user behid a router cannot connectb to the router

[lewar]

Three router A,B & C

A connect to B & B to c

User on A can to B and c but unable to go to the internet.
C is directly connected to the Internet.
User conected to B can connect to the internet as A,B are on the same LAN
A is remote router connected point to point to B.

What could be the problem ?

See attached routes for a,b,c
