Title: PPTP - Whats going on with EFW and PPTP? Possible solution... Post by: effgee on Sunday 13 June 2010, 06:06:29 am Here's the scenario.
I have a PPTP server running on a linux machine Centos 5. POPTOP I have GRE (PPTP Passthru) enabled on my router as well as the PPTP ports TCP/1723. With my Firewall / Router device, everything works just peachy. Fast forward.... Installed EFW.. configured the same ports and GRE pass through. Gets stuck at username and password. Check my logs, see this : CTRL: PTY read or GRE write failed (pty,gre)=(6,7) Lots of Google searching. Come across these two links. poptop.sourceforge.net/dox/qna.html which leads to... pptpclient.sourceforge.net/howto-diagnosis.phtml#read_eproto I kill pptpd, modprobe ip_gre , start pptpd.. And lo and behold I connect with the native windows PPTP client. If I kill pptpd and restart it, it once again fails to connect in the same place. I have to kill pptpd, rmmod ip_gre , modprobe ip_gre, and start pptpd again to be able to connect. WHAT IS GOING ON!? |
