IP not refreshed after few hours

If the router supports updating DynDNS hostnames, you could try that.

Hello Jivin,

From the info you have provided, I think you are using the manual update method by logging into the dyndns and refreshing your hostname IP based on your internet's WAN IP.

This method has it's pros and cons.

Pro: You are unlikely to encounter dyndns banning your hostname for abuse (repeated updates even though the IP has not changed)

Con: It's tedious and inconvenient

You have 2 alternatives as mentioned by VikingTiger and Cry Havok:

• Determine if your modem/router supports DDNS aka Dynamic DNS. Google your modem brand and model if you must. Or look around if you know how to login its web console. You'll know when you find it because these things normally ask for the following:

Service: It can be a list box containing dyndns, no-ip, etc Hostname: the hostname you want to associate with the WAN IP (the one you manually update) Username: your account username Password: your account password Email: your account email address

Pro: Updates are automatic and almost instant

Con: Some brand modem/router have an update abuse problem and this will get your hostname banned. You'll never know until you try, but it helps to google your modem brand and model for issues beforehand.

• Using the dyndns client software requires a PC in the same network as the CCTV to be always on. If the WAN IP changes while the PC is off, your hostname will not automagically update. Basically this is the same as your manual update method, only there is a software running in the background checking the WAN IP and automatically updating the hostname as needed.

Pro: Again, you are unlikely to encounter dyndns banning your hostname for abuse (repeated updates even though the IP has not changed)

Con: Additional expenses

• If neither of the two work for you and you are tired of manually updating. Buy a cheap non wi-fi router. Most routers support it. Refer to suggestion #1 when you get home after picking one up. If for some reason it is not supported, have the store exchange for another item. Btw, I have undesirable experience with the brands airlive and dlink. Linksys and SMC are fine. Have not had the chance to try out other brands.

Pro: same as #1

Con: same as #1 and #2

• If you don't want too much hassle and also don't want to spend money on router or electricity, maybe just install the dyndns client software on your PC at home or your laptop. Turn on the computer a few minutes before you leave for work to give it enough time to update (15 minutes or while eating breakfast should be fine). If it's your laptop, make sure to disable the software most of the time and only enable it when you are in the same network as the CCTV.

Pro: It's a cheap workaround

Con: Turning on and off your PC frequently may shorten the lifespan of it's parts. I'm sorry, but you will have to assume that risk since I provided you other alternatives above.

Hope this was helpful. Good luck with your hostname update. :)

Hi,

thanks for all your help and advice. Managed to solve it. Realised that both my DVR has DDNS settings so I believe by keying the details in both systems result in the hostname being reported as abusive. I request for unblock and disable one of the DVR DDNS setup (since under same hostname). Till date, I do not have much prob....

Thanks all and great weekend.

Based on what you've said it sounds like your current update client is not working. Are you currently using the router's Dynamic DNS update feature?

If you decide to run an update client software on a computer, that computer must always be on for it to work, and it must remain in your home network (because it will determine the WAN IP of whatever network it's located in and use that).

Sorry but I'm not rally good at these network terms. How do I know I'm using the routers Dynamis DNS update feature?

I only know that I had configured the port forwarding in the modem (firewall setting) and then create the hostname in dyndns pointing to my ip address. It does work but the connection is lost after few hours and everytime I logged in to check, I realised the DYNDNS IP address is different from my modem's IP. So I just clicked to refresh the IP in DYNDNS and then I can connect to my hostname again. Then few hours the same thing occured again.

As I do not have a server in my home, it seems the installing the update client is not a solution to me.

Any other solution?
