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
