[pptp-server] GRE being blocked?

[Brian Lalor]

I'm seeing these errors in my logs for one particular client:
GRE: read(fd=4,buffer=804d7e0,len=8196) from PTY failed: status = -1 error = Input/output error
CTRL: PTY read or GRE write failed (pty,gre)=(4,5)

Does this mean GRE (proto 47?) is being blocked somewhere along the line?
