As for the routing. I'm presuming you've got forwarding enabled in your kernel...
echo 1 > /proc/sys/net/ipv4/ip_forward
then you need to add routing, from the virtual machine run:
route add default gw 192.168.122.1 # I'm not sure which IP is your gateway system! THIS IS A GUESS
I'm not sure which IP the gateway system is. I believe it should be the IP of the connection for the FC13 "server" which appears to be 192.168.122.1 but maybe you can work this out?
Simply try pinging various parts of your network, from your "server" system, to your router, to the net itself. See how far you can get packets to help debug.
If you can ping your "server" you know the routing is setup that far, if it goes no futher you know something is then blocking it, etc.
If you end up pinging google? You've fixed it
