Dynamic DNS Hosting

[leeym]

I own a domain, and have found a dynamic DNS hosting company (No-IP) to host this domain for my home network since my DSL Internet connection is a dynamic IP address.

If I have multiple boxes on my network all connected thru a switch which is connected to a DSL modem, how can I enable a web and mail server on just ONE of these boxes. Also, I'm unsure as to how I can route all Internet traffic right to this box without having to worry about security issues towards on other devices

Any thoughts?

Thanks

You need a router to do what you want.

What you could do is grab a cheap box, throw two NICs in it and ClarkConnect (http://clarkconnect.com/), then connect that to the internet and the switch.

All you need is a dlink (http://dlink.com) or linksys (http://linksys.com) router. You want one that supports DMZ (which stands for demilitarized zone). It allows one machine behind the device to be exposed to the internet. The data sheet for this one (http://www.linksys.com/products/product.asp?grid=34&scid=29&prid=142) says it has DMZ support. You can get a more detailed description of a DMZ here (http://searchwebservices.techtarget.com/sDefinition/0,,sid26_gci213891,00.html)

My Linksys wireless router does this but I've never tried it. I do however use NAT on a regular basis. I have the Linksys wireless(802.11b) router that is like $50.

My little DLink DI-604 does this quite easily. In fact, it's port forwarding is pretty advanced, and the interface makes it almost a joke to configure. I've got SSH to 3 different boxes based on port numbers, a web server and a mail server all running through the router.

NO-IP is a good service, but if you want to run your own domain name with Dynamic DNS, you will most likeley have to pay for that through No-ip. It all depends.

Along the lines of your D-Link, you may want to take a look at what ports you have open, some ISP's scan for open non secure ports (Time Warner scans it's entire network for open 25's which can be used as span relays), So make shure you secure your mail ports before you open up your servers IP to the world.
