What to Do When You Forget Your Router's Password and DYNDNS is not configured on your Router

DynDNS works by pointing a domain name at your IP address. Normally, your router would have a setting inside that will automatically send your ip to DynDNS.

However, there may be times when the old system admin might have left without telling anyone the router password or the current admin might have forgotten it himself due to a bout of extreme absent mindedness. There can only be two ways about this:

1) Manual update
2) Automatic update (aka factory reset of router)

Manual Update

First, go to dyndns.com and log in using your username and password. If you don't know the username and password, contact your system admin.

Resetting From Inside the Office

Once you login with the username and password, click on My Hosts (look in the first hand column) and then click yourdomainnamehere. Next click Use auto-detected IP address. Now click Save Changes.

Resetting From Outside the Office

First, ask someone from your office to go to www.whatismyip.com. Ask them to give you the IP address. Use this IP instead of clicking on the Use auto-detected IP address for when you are outside the office.

Automatic Update
If you want this setting to be done automatically by your router, you will need to do a few things:
  1. Identify what services are accessed by people from outside your office (CCTV, Wavelet EMP etc.) and identify which ports they use
  2. Factory Reset the router
  3. Forward the ports for all the services (CCTV, Wavelet EMP etc.)
  4. Enter the DDNS/Dynamic DNS details on the router
Please note that you must be careful about #1 as if you miss anything it will stop working after the factory reset.

This will be much more convenient than resetting the IP every day manually.
