Re: Handing out Public IPs

I'm not sure if you mean a Forwarding configuration, or a Proxy
configuration.

If you mean a Forwarding configuration, where the host running pptpd is
to be a router, and you are giving routable IP addresses to the clients
in the remoteip option in pptpd.conf then:

1.  you must not NAT or MASQUERADE,

2.  you must enable ip_forward,

3.  there must be a route to these IP addresses that identifies your
eth0 as the gateway,

4.  any non-routable IP address is valid for localip.

If you are attempting a Proxy configuration, where the host running
pptpd is effectively a bridge, then:

1.  add proxyarp option to /etc/ppp/options.pptpd,

2.  do not set a localip option in /etc/pptpd.conf,

3.  enable ip_forward.

I've never used a configuration which required iptables.
