Dialup internet using ppp1??!

[hotpotato]

Hi,

At the moment i've got my computer set up nicely with my dial-up internet connection (ppp0) being shared over my network through a firewall script that starts upon boot.

I also have my computer configured to be a PPP dialin server, however in order to allow access from the connected computer I have to flush iptables (as the firewall script is setup for ppp0 to be internet, but when computers dialin, pppd creates the device ppp0).

So, my question is, is there anyway that I can make either the dialin server or my dialout internet use ppp1, so I can alter my firewall script to compensate for both situations (meaning I don't have to flush iptables everytime I want to use dialup server)???

Thanks,
