Showing us the output of "ifconfig ppp0" would be a useful thing.
Perhaps you need to turn on proxy arp, if its not already. Something
echo 1 > /proc/sys/net/ipv4/conf/ppp0/proxy_arp
The reason you need this is because your 212.240.214.1 route is not
specifying the far-end of the connection as a gateway.
You can (and probably should) despence with the proxy_arp, and ensure
that your ppp0 interface is correctly setup with a P-t-P entry. If
you're bringing up the interface yourself, just remember that you say
"pointopoint", _not_ "pointtopoint" (that tripped me up for ages one
time.
