[pptp-server] CTRL: PTY read or GRE write failed (pty,gre)=(5,6)

[Mark Burring]

I have deplyed PopTop so several servers to replace M$ vpn capability
(mainly because W2K cannot multihome without dying) and one machine I
get these errors:
 
Nov 22 13:52:22 perth pptpd[16100]: CTRL: Client ***.***.***.*** control
connection started
Nov 22 13:52:22 perth pptpd[16100]: CTRL: Starting call (launching pppd,
opening GRE)
Nov 22 13:52:22 perth pptpd[16100]: GRE:
read(fd=5,buffer=804d8a0,len=8196) from PTY failed: status = -1 error =
Input/output error
Nov 22 13:52:22 perth pptpd[16100]: CTRL: PTY read or GRE write failed
(pty,gre)=(5,6)
Nov 22 13:52:22 perth pptpd[16100]: CTRL: Client ***.***.***.*** control
connection finished
 
This problem is listed in the FAQ and is caused by it being behind a
firewall. However in this case, the machine is not behind a firewall, it
is the firewall.
 
I have
1) added entries to the box's firewall to let 1723 and proto 47 through
(not that they were being blocked in the first place)
2) tried flushing the box's firewall rules
3) tried binding poptop to the external interface
 
The only thing of note is that the kernel is patched to Masq pptp
however its not being used in this case.
