The best solution is to install a dynamic DNS updater that speaks dyndns2 protocol on your "small web server". A good updater does not continually ping your external IP, but rather does an appropriate check at reasonable intervals and at startup.

Hi, It seems to be that some of us are in this same position of setting up a new server.&n...
It seems to be that some of us are in this same position of setting up a new server. I read this post, and I'm not trying to hijack this thread but I could sure use the help. I just received a new Comcast Cisco modem a couple of hours ago which replaced our approximate 10 year old SMC.
My only diference is with the Domain Controller. At this particular time, I'm more comfortable having the DHCP issues left with the Comcast unit. I'm also running the Windows Server 2012 R2 Essentials product suggested by train_wreck. I'm also not "under the gun" to have the entire system up and running since I've got my approximate 10 coworkers setup running Office 365 with Microsoft handling the Exchange server duties. I've also established a relationship with a cloud storage provider (Egnyte) who is handling our "shared file" duties. Our PC's are running an Egnyte sych client in real time that works for the most part pretty good. I've created a workgroup in Win 7 and we share files that should not be in "the cloud" off of our Office Managers PC. I recently down sized our company at which time I just couldn't afford the Data Suite Citrix Solution with 4 servers (I believe that's what we had), an Exchange server, and all the other IT Company costs.
My main issue is that I can't grasp the DHCP, DNS, the IP Suite of protocols, Private IP, Public IP, Subnet Masking, Port Forwarding, Gateways, and associated items. I've studied, watched, read, etc... and I'm becoming more familiar but it's not going to happen overnight. What our company needs is really:
1. Remote Access (Anywhere Access). We work at our clients sites 75% of the time. I also have some coworkers that may be gone for 1 week at a time. Our end product is really just reports (Word and PDF), spreadsheets, Publisher documents, and a few others. My issue with this has been the uPnp or lack thereof with the SMC modem. Also, would Anywhere Access be best accomplished using a VPN? We do have 1 static IP address and really it doesn't look like we really need it????? What is it used for.
The other issues such as shared printing (we have two large capacity multi-function copier/printer/scanners, and file storage are not as baffling to me. what I am most concerned (I should say SCARED) about is setting up the Comcast unit incorrectly, having the network go down, or leaving us exposed to in a matter which could jeopardize our clients.
I'd go for the domain controller being the server if it was recommended, but I'm just fearful of messing something up. I've tried hooking up with local IT providers but they want the servers again in a Data Center and the cost is just overwhelming.
Any suggestions would be so helpful and I'll move this post if anyone feels I'm hijacking the thread. But, the other posters situation is something that I could deal with so I'm just trying to learn and piggy back off of the same topic.

Yes, Comcast's responsibility technically ends at the Comcast gateway; any devices past that, they are not authorized to provide support for.
But I am, so let's dig in
First off, if you are using the server to provide DHCP (and you are in this case), you will need to disable DHCP on the Comcast gateway.
Can you possibly detail your network topology (any routers and their associated IP addresses/subnets, the server's location on the network & its associated IP address/subnet). As well, can you post the output of "ipconfig /all" from a workstation that has obtained an IP address via the WIndows DHCP server?

Timd; Thanks for the sharing of the educational materials. I spent yesterday watching video's on Lynda.com by a gentleman by the name of Mark Jacob. The ipv4, ipv6, subnet masking, and the actual math behind this all really helped me greatly. Some of the "vague references" supplied by others were explained. I did purchase a couple of books albeit not highly technical in nature, and the IP addressing is considered "outside the scope of the book (i.e. topic). I was dumbfounded by that since it's the inroad to the system. But it is what it is. Being that Eli's video's on the topic are 2010 - 2011, he really didn't even touch on ipv6 other than he's been hearing about it since 1999 when he got involved in computers.
I've been involved with forums (not Servervault) in my main line of work. However, I stay back and let the people attack each other by use of sarcasm, terse one line comments, and literally making a person feel like an idiot for even posting a question, comment, or concern. I'm also aware that the IT industry has some very highly skilled, educated, and professional people that should not be giving their knowlege away for free. Hey, not an issue with me as I'd pay for the information I need. I'd be happy to give the list of what I have, what I'd like to do, and fill in the information on all the devices. If I could learn by reverse engineering or if the person doing the configuration would at least tell me why, I'd appreciate that as well. I'm not messing with anyones' job security but I am a Scientist, and not knowing anything at all, drives me nuts. Not to mention, I do enjoy technology as well.
If you'd like to chat more off this site, you can email me at trisATgoisesDOTcom. Replacing the usual AT and DOT with the correct characters. I don't want to impose on the fine folks that run these forums and their helping nature.

I've OBVIOUSLY high-jacked this thread and ALSO cross-posted with my IPv6 dilemma.
So here on out, anyone interested in what I got going here, here is a seperate thread with my IPv6 problem:
Thank you both train_wreck and ShifterKartRacer for the awesome detailed help! Sorry OP! Your post is very similar to my scenario..but the IPv6 has made it more complex.....I honestly didn't mean to step on your toes... : )

A domain registry like register.com is only authoratative for forward records like A records and MX records. You can only setup PTR records with the hoster of the IP address block - in this case Comcast.
The by the book process is contact Comcast on the phone Mon-Fri 8-5pm Eastern time.
Incidentally your PTR isn't correct. Take a look at the following:

Forward and reverse records only exist for hostnames not domains.
A domain (estarmail.com) can have a MX record and it can have an A record but the MX
record is only used for routing mail. The A record is not. CNAME records are not used
for routing mail at all. Setting a PTR (reverse DNS) record to point to a domain instead of
a hostname is nonsensical.

For SSH to work on a Linux machine behind a NAT router, you will need to port forward TCP port 22 to the internal LAN IP address of your Linux machine (in your case 10.1.10.135), and to connect to it from other locations on the internet you will need to use the global static IP configured on the router.
Can you please clarify:
-Is your Linux machine connected to a separate router (whose WAN is configured with your Comcast-provided static IP), or is the Linux machine connected directly to the business gateway?
-What do you mean when you say "I've set up /etc/ssh/sshd_config to all port forwarding."?
No problem, I'm glad it has been resolved
thanks for the help, sorry I didn't say so sooner

2. Select Websites from the Manage Services menu.
3. Select Edit website.
4. In the Control Panel under Manage Services, select Domain Name.
Once inside the DNS entry menu, please update your records.

I have not used this device personally, but i believe it is just a standard eMTA; it is intended to be connected to a standalone router, which you would then perform port forwarding on. If it DOES have such a capability, the interface would be accessible at usually http://192.168.100.1 or http://10.1.10.1
We would need some more information as to which port you would like open, which protocol(s) to be used, and to which destination inside your LAN.
