Subject: Re: LT WinModem Problems

Ok,

I disabled the firewall completely using:

  /sbin/ipchains -F input
  /sbin/ipchains -F output
  /sbin/ipchains -F forward

but still no luck.  Might it be a modem initialization issue that is messing up the packets?  Where would I find out the initialization strings to use?

What about the netmask being set to 255.255.255.255 instead of 255.255.255.0?  I do set it to that in the ppp/options file but it seems to go back.

I'm starting to run out of ideas on what it could be.

Thanks for all the help,
Darren
