With some safe reasons, I need to sniff pptp cleint request packets, then to get dst ip and src ip, for example 10.5.1.100 -> 218.100.211.100 , I want to know the correct rule in tcpdump

tcpdump -i ethN port 1723 -vvv

Assuming that you literally just want to see the connection information and not run a packet cap.

Replacing ethN with the appropriate interface.
