My router has a public IP and my computer is in my LAN. So naturally I'm going to masquerade outbound(me -> Internet) traffic to make it possible to access the Internet. My settings:(I can't embed images yet...so please follow the link)
In the picture, if I uncheck
Masquerading in the second line, I'll lose my access to the Internet. And through
iptables-save I found that the
MASQUERADE target for the chain
zone_nat_wan in the table
nat is gone.
So here's my question: doesn't
wan ⇒ lan mean the traffic from WAN to LAN? If not, what does it mean?
P.S. My router runs OpenWrt Attitude Adjustment 12.09.
