Loose packets

[ross]

Dear all I have recently built a firewall for my home office. All seems well, it’s fairly secure. One problem though, every time my Windows client sends a packet destined for my Linux box that is not destined for the Internet (say for example when I use PUTTY over SSH) PPPD dials up. I am pretty sure I need to set up a firewall rule to stop this, but I have tried several iptables rules all to no avail.   Any guidance is much appreciated   Ross
