On a far more pleasant subject: Attention tech-heads

[docwebster]

Specifically, attention those who are familiar with Linksys wireless routers.

What I need to know is about port forwarding I guess is what it's called. I would like to point port 1221 (for the SAM software that takes the requests when my show is live) to another machine on the wireless network instead of this one I'm on at the moment.

How do I do this?

Use your web browser to log in to your router:

http://192.168.1.1
user: admin
password: admin
(or whatever you've changed it to)

go to Network Settings
Forwarding

and fill in for port 1221 and the IP address of the machine you want to get the forwarding.

I'm a bit confused by your statement "instead of this one I'm on at the moment". Does your software work on that machine?

Oh, it does. It's just that the one in the living room is also capable and has one hundred and twenty gig of tunes to draw from.

The reason I asked is because either 1) you already have port forwarding set up for SAM, just going to the wrong machine, and so you just need to change the IP address, or 2) you have the machine its on now in your "DMZ". I've never worked with DMZed machines so can't be of much help there.

I grasped that you had a good reason to run the software on a different machine *grin*.

You don't have to set a static IP for the machines. Even a dynamic IP will usually remain constant until the DHCP server is rebooted or a given client stays off line for a long period of time. I have port forwarding and DHCP in my NetGear router, I just have to change the destination IPs for the port forwarding every now and then.

SAM: here's my guess

Oh you would have to ask while the linksys site isn't working.

Anyway, the basics should match what I'd do to set up the same thing with my D-Link gear. The following isn't based on the instruction manual but instead on NAT (Network Address Translation) in general.

Ignore the wired or wireless state of your computers. They're on your LAN. The hardware can figure out how to reach them by their local addresses.

Set up the local addressing either by using "static DHCP" where the laptop gets the same IP every time or by using static IP addressing where the OS uses the same IP every time without even asking the router. The point is that the device running SAM should always have the same IP address on your local network.

Once that's done you have, on the router, a list of external addresses and ports that connect to internal addresses and ports of things on your network that offer services in response to requests from outside. Give that list the address and port of the laptop running SAM and you should be on the air.

With cheap off-the-shelf routers like the D-Link and Linksys models there is a limit to the number of internal services you can expose this way. With the D-Link it's twenty, on paper. I haven't tested how many connections can be in use at once.
