Doing a PortScan of my VPN IP address gives many open ports

Question

Hi guys, I got the feeling I'm asking an already answered question,

When I create a VPN connection, I get an IP address in the country I chose.

When I do a Port Scan of that IP address (for example with nmap) I see allot of OPEN ports.

>> nmap ***.***.***.***
Starting Nmap 7.70 ( https://nmap.org ) at 2019-**-** 16:37 WAT
Nmap scan report for ***.***.***.***
Host is up (0.079s latency).
Not shown: 979 closed ports
PORT     STATE    SERVICE
22/tcp   open     ssh
25/tcp   filtered smtp
53/tcp   open     domain
80/tcp   open     http
135/tcp  filtered msrpc
139/tcp  filtered netbios-ssn
389/tcp  open     ldap
443/tcp  open     https
445/tcp  filtered microsoft-ds
465/tcp  open     smtps
993/tcp  open     imaps
995/tcp  open     pop3s
1198/tcp open     cajo-discovery
1723/tcp open     pptp
2000/tcp open     cisco-sccp
4443/tcp open     pharos
4444/tcp filtered krb524
4445/tcp filtered upnotifyp
5060/tcp open     sip
7070/tcp open     realserver
8443/tcp open     https-alt

Nmap done: 1 IP address (1 host up) scanned in 6.48 seconds

note: some data is obfuscated with '*''s

The thing is, I'm sure I do not have these ports open or such services running.

QUESTION: Can somebody explain a bit what these ports are and how this kinda works.   And in the case I have a service/port open how would I see it and am I 'safe'.

Many thanks, and merry Xmas/newyear..

Hello,

What you are seeing are service ports - these ports are used by various services, they are not used for the default services they report.

Remember, the point of the VPN is for A LOT of people to be sharing the same public IP as you. So many ports will be open because they are the communication port of a client on that vpn server. that is the vast majority of the ports you see as open. https://torguard.net/tgspec.php

Also, any forwarded ports that the many clients might have will appear as open; especially if the software on the other side of that port isn't doing source filtering. These do not lead back to YOUR machine.

Open VPN is designed to work this way so no worries!
