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

[Jens Werner]

Hello Beat,

> Nobody having problems or not using pppd with dynamic ip?

using pppd with dynamic ip uplink at a customer's network, no problems
so far.

This is just a masquerading machine with an openvpn bridge to the local
ethernet device using voyage 0.5-2. My basic iptables script in this
case is a:

iptables -t nat -A POSTROUTING -s $NET_LOCAL -o $INT_INTERNET -j MASQUERADE

NET_LOCAL and INT_INTERNET jsut are the local netmask and the ethernet
device with the ppp connection.

As for connection tracking the script loads the following modules:

modprobe ip_conntrack
modprobe ip_conntrack_ftp
modprobe ip_nat_ftp

Except for some anti-spoofing rules all chain policies are set to
ACCEPT, so we don't filter outgoing traffic here.

Are there any packets dropped by iptalbes (see "iptables -L -v")? Maybe
you have some weird packet filtering problem? Might be a good idea to
try out policy accept on every chain.

If I could be of any help, let me know.

Greetings
Jens
