Changed Router, Now Lotus Notes Webmail Won’t Work

ibm-dominolotus-notes

I'm not a systems engineer, but I can do the basics. I've inherited a Lotus Notes setup in my new job. I've no experience with Lotus Notes/Domino, however.

Everything was working fine.

Today the router died and I replaced it (with a D-Link DSL-2740B). Setup seemed to go okay, and Lotus Notes works fine for computers within the LAN. It also works fine for sending emails to external addresses.

It doesn't work outside the LAN: people cannot connect to the server, and we're not getting any emails that are sent from outside addresses.

Webmail (previously at mail.mycompany.com) doesn't work any more (it fails with a "The connection to the server was reset while the page was loading." error).

I strongly suspect that this is a port forwarding or firewall issue. I've tried forwarding ports 80, 1352, and 25 through to the correct server. A port scan shows that ports 25 and 1352 are fine, but that port 80 failed with a "No connection could be made because the target machine actively refused it" error.

So I'm stumped. I don't know how the old router was setup to allow the webmail or notes traffic in. At this moment in time I'm more concerned about getting webmail up and running because that, at least, will allow people to start collecting emails.

Please do point me in the right direction for further diagnosis, reading, or whatever I need to do to get this fixed. Thanks!

There are a few checks here and few things to note.

  1. Please change your router - I have looked at the router manual and it doesn't allow port 80 to be changed from the router config. This means that you won't be able to host the website on port 80 anymore. I would recommend a proper router like Cisco or Draytek if the budget allow for it, if not at least Netgear - most Netgear router will allow you to change router port.
  2. Check whether you have static IP or dynamic IP. If dynamic, is dynamic dns service being used at all?
  3. Check SMTP port on the server: http://www-12.lotus.com/ldd/doc/domino_notes/6.5.1/help65_admin.nsf/b3266a3c17f9bb7085256b870069c0a9/9e2e02ebb636acc885256dff004b1f2a?OpenDocument and enable it on the firewall
  4. From your command prompt ping mail.mycompany.com and check which IP address is being displayed to confirm whether mail is hosted inhouse or externally or if it goes through a spam filter service. Also do the same for the website and see what the ping reveals.

Hope this helps you in resolving the issue.
