I am having trouble running pppd using the active-filter outbound option. I am using FC2 with some things from development, in particular: ppp-2.4.2-3.1 libpcap-0.8.3-4 kernel-2.6.7-1.471 on a dual athlon system. The error message I am getting is: pppd: error in active-filter expression: inbound/outbound not supported on linktype 0 This makes it seem like either the kernel or ppp is checking the link type before ppp has set the link type.
