Hi !
I'm having some problems configuring my DMZ with adsl fixes ip's.
My ISP give to me 1 ip for the connection fase (213.13.123.140) and others ip
for my netroking needs (213.13.121.72/29)
My modem connects very well (looking ppp.log), I was pinging once but didn't
nat.
Now it does nothing !
dmesg shows:
natd: tun0: Cannot get interface address
pinging some valid ip from internet:
ping: no route to host
netstat -nr
