everything looks fine. I'm not quite sure about the "policy" module, I
did never use it and it is somehow being used to check the "direction"
of packets. Maybe someone else can comment.

So remaining things to check would be
- where do packets do what? Use "tcpdump" on the router to monitor
  how packets flow. Don't cite all the output, but look at where
  packets are coming and going. Two terminals with "tcpdump -i eth0"
  and "tcpdump -i ppp0" would tell you that. Send a few pings from the
  desktop to the internet. Also try pinging an IP from the desktop, not
  just hostnames (to rule out nameserver borkage).
- is forwarding actually really enabled? Just "cat" the
  relevant /proc/sys/net/ipv4/ip_forward.
