[pptp-server] ARP Binding ?!?

[Timothy Findlay]

Hi,

My conf file looks like so....

option /etc/ppp/options
localip 128.1.6.2
remoteip 128.1.6.38-40
listen 203.44.64.xxx

I originally had the localip setting set to 128.1.6.35-37 but I figured if
they could all tunnel back through my main private IP (128.1.6.2) on the
box, this would save some IP's.

Just for ref. my options file looks like...
name atgproxy1
ms-wins 128.1.6.7
auth
require-chap
proxyarp

Thanks for your reply.... any other thoughts/ideas welcome ....

Tim.

Timothy:

What is your local ip & remote ip set to in the pptpd.conf file?
Should be from the private lan address range.
