[Voyage-linux] Anybody using pppd on voyage-0.5.2and masquerading?

[Hofer, Hermann]

Hello Jens,

we call the firewall script out of pppd's ip-up.d directory and query the interface for it's IP.

We use "-p XXX" in every iptables command for better understanding, this is common standard here.

If you are interested I can send you an example.

Hello Hermann,

I'm just curious, but how do you get the external ip with a dynamic ip 
uplink? As to iptable's manpage, MASQUERADE is the target to use in such 
setup.

Oh, btw: You can leave "-p ALL" because this is default.


Regards
Jens
