D-Link appears to block email ports??
« on: November 02, 2018, 06:05:20 PM »

I am a century link subscriber.  They provide a wireless router.
I bought a D-Link DIR-867, which is also a wireless router.

The century link router only services the century link boxes in my house, plus my media server.
I uplink the DIR-867 to the Century link.  Everything works perfect, EXCEPT, email ports are blocked.

If I connect my android phone directly to my century link wireless, email works fine.  This proves that century link router and century link service are not blocking my email ports (993/587)

If I connect my android phone directly to my DIR-867, the email ports are blocked. 

I reset the router to factory settings, there is no port forwarding, no blocking of any kind that I can find.  I checked every single setting in the router.  I cannot find any reason why the email ports are blocked.

Any ideas why I cannot use email ports on my DIR-867??

  • What region are you located?
