[pptp-server] remote win9x clients fail, clients on the LAN connect...

[Hervé Guehl]

Seems like protocol 47 is filtered somewhere .. 
Perhaps in your VPN server ?
configure iptables to accept protocol 47 on external interface...
(iptables..... -p 47 -j ACCEPT)

  Hi, 

  Have just setup poptop on a server. Machines on the LAN seem to connect and function correctly (one win2k machine, one win98se machine), however, when a remote client (win98se) tries to connect, it fails with an error I can't seem to find anywhere in this mailing list, or anywhere else, below is the output of the log...

  This is what happens when trying to connect from a remote dialup...

  This is what occurs when connecting over the LAN...
