Can somebody please explain something to me?
# use MASQ if you get dynamic ip iptables -A POSTROUTING -t nat -o eth0 -j MASQUERADE
What's the difference between using "-o ppp0" and "-o eth0"? Obviously, one is using the ppp0 interface while the other is using the eth0 interface. But in terms of what happens to the packets, what's the diff?
Out of curiosity, I tried both: ppp0 works, while eth0 does not. Cheers, Dave
