[ILUG] Dial-on-demand question

[Barry Redmond]

Hi,

This isn't strictly a Linux question, but someone here may have 
encountered the problem before so I'll ask...

I've set up an old PC as a Linux dial-on-demand gateway for a small 
LAN of Win95 machines.  I've used pppd and chat and everything works 
fine, except that I've noticed that if a Win95 user closes down their
Netscape browser when the dial-up link is down it causes the gateway 
to dial out.  Does anyone know exactly what/why the browser is 
transmitting? Is there any way to stop it doing that?  Is there any 
way to identify these packets at the gateway & prevent them causing a 
dial out?

Thanks,
Barry Redmond
