Hi,
I have a pppoe connection with dynamic IP address. ppp works fine but address translation doesn't, i.e. I can't connect to 213.190.39.183:80. I don't want to run apache on tun0 as it is dynamic. Is there some solution?
ppp.conf:
nat enable yes
#nat log yes
nat port tcp 127.0.0.3:80 80
ifconfig -a
ed0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
