[pptp-server] Control over device name (ppp0, ppp1, ppp2)

[Michael Bailey]

Hi,

I am running pptpd on a linux box that sometimes uses a dialup 
connection to the Internet.
The firewall is setup with the assumption that ppp0 is the dialup 
connection to my ISP.

Now that pptpd is running there is a chance that ppp0 will be taken by a 
pptp connection.
I need to be able to uniquely identify the device name for the dialup 
connection.  Can anyone
suggest how I could somehow do this?

I would like to make pptpd leave ppp0 alone or else make it use another 
device name.

Any help would be greatly appreciated! :)
