Do this:

# ip ro add default dev eth0
# echo 1 > /proc/sys/net/ipv4/ip_forward

You should be good to go with lots of wholes and besides the
192.168 netblock would never see any responses back.

Then you do:

# iptables -t nat -A POSTROUTING -o eth0 -j SNAT --to <your static ip>

This makes sure that your private LAN can get out meaningfully.

Then go and read alot on iptables to _harden_ your box ;-)
