I'm sure you've already done this, but just in case have you set your
computer to act as a gateway to the FR? It needs packet forwarding
enabled under /proc/sys/net/ipv4/ip_forward as well as iptables set up
correctly. Personally I use an iptables frontend called firehol to
simplify this.
My /etc/firehol/firehol.conf looks like (this is on my laptop, not the FR):

#always needed for firehol
version 5

#Don't let anything in from the Internet that I didn't request
interface ppp+ internet src not "$UNROUTABLE_IPS"
  protection strong
  client all accept

# Accept all client traffic on any other interface and allow incoming SSH
interface any world src not "$RESERVED_IPS"
  server ssh accept
  client all accept

#Forward packets from usb network with NAT
router usbnet inface usb0 outface any
  masquerade
  route all accept



Cheers,

On the day *I* go to work for Microsoft, faint oinking sounds will be
heard from far overhead, the moon will not merely turn blue but
develop polkadots, and hell will freeze over so solid the brimstone
will go superconductive.
