Dynamic DNS setup.

[jian0203]

Hello, everyone. I am a new here. I hope I can learn something from you guys.

In my company, we have ISP which provide dynamic IP address for internet service. Since it's a dynamic IP, I should install Dynamic DNS in order to have my dynamic IP update to the domain so that people will be able to reach the server such as e-mail and website. The IP will change once the modem or router is restarted.

We have our own server in the office. My problem is where should I install the dynamic DNS? I have referred to many websites related to DDNS but I still get don't it.

I tried so many ddns software which installed in the pc, such as dynu, dyndnds, no-ip, dns4me, freedns.afraid.org, etc. I think it shouldn't be installed in the pc but in the router? If it should be configured in the router, is it the port forwarding configuration will solve the problem?

I am not sure whether my doubt is correct or not. I spent days with this already. I am kinda lost now.

So I might need some suggestion from you guys. Please give me some direction.

Thanks in advance for helping.

You are doing it right. Install the DDNS client from your DDNS service onto a cmputer that will run 24x7. I've been using no-ip for years, works great. I ran the client on a Windows XP pc first, then a Windows 7 pc.

I will address your question of the router DDNS client. To do this, you will need to use a router that supports this.. I don't know of any business routers that do this, but if you're using a SOHO (small office/home office)router that supports a third party firmware like DDWRT or Tomato, then some DDNS clients are built into the firmware.

I use a Linksys E3000 router, and this support DDNS from a large number of services. including no-ip.


To address this problem overall: Who is your ISP? Do they provide static WAN IP's to business accounts? Have you discussed this problem with your ISP?

Do you not have the option at all to get a static IP address? While your method can and does work most of the time, if you are hosting a server at your site it really is preferable to have a static IP.

I am not really sure whether my router support ddns or not. I will need to check on it tomorrow.

But we need to pay for no-ip for the ddns service, isn't it ?

It's said that there are many ddns service provider but it ends up we need to pay for their service. Any free service provider? I might want to try it first before I go pro with the services. Thanks for the guiding. I appreciate it a lot.

Yeah, I know static IP would help. It is just that the service provider charges are just too expensive. It's like USD$100+ per month. So, i don't think it worths.

for the guys hosting their own site. Don't you have a lot of sleepless nights in regards to security. Do you run it on a separate vlan?

Yes, we do run it on a separate vlan. I am not that familiar with the network yet.. But as I know, they installed firewall as well... We are just a small company..So, I don't hackers are interested with us. Lol.

Maybe I will do more security measurement later since my major is security tech. Just try to learn as much as possible.

I do not pay for no-ip.com's service. once a month, they send me an email that informs me my hosts will expire if I don't validate. This is what they do to you when you get their "free" service. They make it an annoyance.

Bottom line, you're going to pay to play. Either pay for a static IP, or pay for the DDNS. I vote for static IP for a business situation.

If you register your domain at Namecheap, I believe that they have a free DDNS service and client.

I actually use OpenDNS and their free DNS-O-Matic.

I get better nameservers and I can manage multiple dynamic DNS clients.

I update DOM through my router so I don't have to install a client anywhere.
