error: "PTY read or GRE write failed"


I have a similar problem. Have it working from a WinNT 4.0 and from one
Win98 on the local network. When I try connecting a Win98 via internet it
doesnt work. 

As far as I see it the Win98 is correct configured (no encr, req pass, no
compr, only tcp/ip and so on). The Win98 disconnects after a while trying to
auth.

My only thought right now is that the remote Win98's firewall thats
filtering out packets so that they never reach us. Could it be that they
don't allow RAW??

>It works on 98. That's what i use to test. As far as i know we've been
ignoring set_link_info packets forever and it's never broken things before.
90% of poptop problems are pppd / windows ppp misconfiguration issues. make
sure encryption is off on 98 for example...
