My apologies, MacOSX 10.2.1 (Build 6D52) Internet Connect VPN feature.
I need to know how to set the mtu and mru to something less than 1500 bytes for the PPPoE (ppp0) connection.
Also, once the mtu & mru are set correctly, I want to be able to modify the routing tables so that my internet requests go straight out through my cable modem and not try to go through the VPN. My VPN connections are at 10.1.* and my Airport connection is at 10.0.*
Thanx for all the help,
