Good morning all. Could someone review the ports I have open on my router? Worried about network security.

I am using the following packages with remote access

Synology Drive
Mail Server Plus SMTP and POP
Mail Plus
Media Server/DS Video
Web Station hosting websites

I have the following ports open for both UTP/TCP:

25
80
143
443
465
587
993
5001

Thanks in advance
 
Stop forwarding all ports until you see a specific need. Don't blindly follow DSM recommendations. If you don't understand why a port is open, then close it until you do.
Hopefully 5001 is just an example number.
 
Don't forget to run the Security Advisor, regularly.

Default ports used by DSM and its packages. Some may be changed, and some should be changed (where DSM permits it).

It really depends on what you you intend to expose to the Internet. Does anyone still used POP3 mail? If you want to ensure secure IMAP4 then only allow access to that port. And Synology Drive access port has to be TCP 6690 for desktop agents (Mac and PC), it's not a Web service.
