Howdy- I'm running 2.2.2-R, and userland ppp. Here's the question: are there any obtuse, obscure reasons why my FreeBSD box would _stop_ forwarding IP packets? I have 'gateway_enable="YES"' in my rc.conf file, which does enable IP forwarding in my kernel: # sysctl net.inet.ip.forwarding net.inet.ip.forwarding: 1 I do have 'add 0 0 HISADDR' in my ppp.conf file, which does successfully add a default route: # netstat -rn | grep default default 205.161.0.7 UGSc 3 1 tun0 But, despite all of this, my other machines can't get out, and I can't ping in to them. The silly thing is, I _had_ this working back in November, but then, a month ago, it rotted, and now, I can't seem to get it to work. Obviously, I somehow affected this magically, rather than the hardware/software rotting, but, for the life of me, I can't guess how I could have such a thing, nor how I would detect the point of failure... So - a reprise of my question: despite my (seemingly) correct setup, what _else_ could be in the way? I'm *this* close to building the bpf device, to try to see if packets are even getting to the ppp process.... -- Brian Reichert reichert@numachi.com 37 Crystal Ave. #303 Derry NH 03038-1713 USA Intel architecture: the left-hand path
