Well, I'd be working on this problem except a seperate problem has popped
up..  I installed pppd-2.3.8 thinking that that might fix my gatewaying
problem (the ip_forward is set, btw) but it hasn't.  Also, the ppp
connection dies after about 15 seconds and pptp has this to say:

If any of you can shed some light onto the subject in regards to why the
xmit is failing on decaps_hdlc and the ptyread/grewrite stuff, I'd be most
appreciative.  I checked the permissions on /dev/ptyp0:

crw-rw-rw-   1 root     tty        2,   0 Jul  8 10:36 /dev/ptyp0

I don't know if its a pty problem or not.


Thanks,
