[pptp-server] PoPToP and Firewall config ?

pptp uses TCP PORT 1723 and PROTOCOL 47.
GRE is a protocol (just like TCP is a protocol), not a port.

port 1723 (pptp) could be in /etc/services, but it doesn't need to be
  pptp   1723/tcp    # Point-to-point tunnelling protocol
protocol 47 (gre) could be in /etc/protocols, but it doesn't need to be:
  gre    47    GRE   # Generic routing encapsulation

The "Max connections reached" error probably is a result of not having any
localip or remoteip addresses defined in the /etc/pptpd.conf file.  You
should have something like the following:

	debug
	option /etc/ppp/options.pptp
	localip  192.168.1.80-89
	remoteip 192.168.1.70-79
