SuSE 11.3/64 pptpd vpn fails to send gre packages

crcanassr · 10-28-2010, 04:28 AM

I just setup a SuSE 11.3/64 server and I am trying to setup pptpd for a vpn. I noticed thatg the ppp0 (or any pppx) interface is non-exoisting and I think that that is the problem why my gre packages are not being sent by pptpd (as I have checked all other options). I have tcp port 1723, and protocol port 47 (gre) open on the firewall (SuSEfirewall2). I have traced the responses using tcpdump and only when the server sends gre to the remote client, the client never receives it (the 1723 connection is established). I checked the old server (SuSE 10.2) that worked the vpn fine, and the only thing missing on 11.3 is ppp0. All other hardware (routers, etc.) are the same. I suspect that pptpd tries to use ppp0 and the interface is non-existing. I can remotely ssh to the server, dns works, samba works, everything else works. Is it something I am missing? How do I create if ppp0 and link it to eth3, the internet gateway? Do I need ppp0?
