you shouldn't have a default gateway on your internal interface.
default gateway == gateway of last resort; i.e., there's one (barring
some specific multipath routing situation).

my guess is that you haven't created an outbound MASQ/SNAT rule (at
least you don't say you have):
# IF YOUR ETH0 IP IS STATIC
iptables -t nat -A POSTROUTING -o eth0 \
-j SNAT --to-source xxx.xxx.xxx.68
-OR-
# IF YOUR ETH0 IP IS DYNAMIC
iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
-j
