1723 is for PPTP's control channel. The actual payload is nothing more

It depends on the type of VPN you're using.
PPTP
Control channel: TCP port 1723
Data channel: PPP over GRE (IP proto 47)
L2TP
Control channel: UDP/TCP port 1701
Data channel: UDP
IPSEC:
Control channel:
- IKE: UDP port 500
-
Data channel: ESP (IP Protocol 50)
or AH (IP Protocol 51)
or UDP
So, to answer your question, it depends.
