Networking questions.

[einstein1981]

Hello this is a point me in the right direction post.

This is what I want. I have a home network, with a linksys wrt54gs router. about 3 pcs and a macmini.

Now I want to create a way to access them all from outside without having to forward ports.
This means that I 'd like to have a way of accesing them in this manner :

host1.domain.blah
mac1.domain.blah
etc...
.
.
.

Now this is what I have:
Linksys wrt54gs router
dynds system embeded in the router.

Also I would like to know if for a domain I can use my dyndns or I might have to register an actual domain:

my ddns is name.homelinux.org
could I have something like:
host1.name.homelinux.org
mac1.name.homelinux.org
etc..
is this posible?
what is it called?
and where do I find examples and guides on this..

Thank you for your patience...

charles

Hi,

I think its not really easy to do a name based resolving for only 1 IP. I know it works with apache name-based virtual hosting, but this relies on the Browser to send the name. If you use a service like e.g. ssh, the name gets resolved to the actual IP before the request reaches your router so there is no possibility for the router to tell with which name you called your ssh client. But this is just my guess from what I know, I might be wrong with this.

for the ddns-question:

There is an option "Enable Wildcard" in the dyndns options. If this is enabled, you can put any subdomain you want in front of your ddns-address and it gets forwarded to your IP. I use this to do name-based virtual hosting for my test apache-server.

Do you have that many public IPs available? You'd have to number up the machines and don't have the router NAT.

I've thought of a few ways to do it, then they fall flat on thier faces.

The only one that is passably usable is via vpn, if you want to connect from different machines around the world, forget this idea, but if it's your laptop setup a vpn on one of the machines, and have the hostname you want to use for each host in /etc/hosts, the routing table will find them via the vpn connection.

It will work with ipv6 but there isn't the genreral infrastucture/support for what you want just yet ( I don't know of an ipv6 tunnel broker that will give you a static ipv6 address against a dynamic ipv4 one, or alternatively a dynamic ipv6 dns service, sorry )
