Historical Document

These pages have sat here since 2008 with no update. In that time the AIM servers have been closed down (2017) and iChat has been superseded by Messages. That effectively make this a sort of Historical Document of how it worked.

I will make attempts to renew and refresh Links to either the most current site or use the Way Back Machine Archive so that people can at least look at what was used. I will make Edit Notes on this and on those where I can find no link to replace the older one as I go through the document.

1 Modem NAPT Settings

02-10-2006

This is the first of the Thomson Alcatel modem's pages

In this device the settings akin to Port Forwarding are called NAPT (Network Address and Packet Translation)

They are Accessed is Advanced > NAPT, as shown by the yellow highlights and arrows. Then follow them left to right.

At this point the actual screen you see will have a smaller gold section at the bottom but where it currently says "Apply", it will say "New". Clicking "New" will expand to this view. The view shown here shows "Temp" entries because NAPT is not ON for this device.

The arrows then lead to where I have entered "This for Your IP" is where you type the IP of your computer (or router if that is the next device).

I have gone straight past the "Outside IP" box as this setting of 0.0.0.0 is the recognised way of accepting incoming data from anywhere on the Internet (which is what you want with iChat or any online game for that matter).

Just above that is the Protocol choice.

I have gone on to enter the incoming (strangely labeled "Outside") port of 5190 and then the port on the next device ("Inside"). As we want anything coming to the modem on port 5190 to go to the next device on port 5190 both are the same.

This device can only enter one port at a time. It needs, therefore a total of 31 entries for the fact two of the ports require UDP and TCP to be set and this device does not have a "Both" or "Any" setting in the Protocol choice.

This set of three pictures are mainly to show the differences between this and the Linksys pages. I hope that from between the two sets you might fathom your own device(s) better.

As another example here is a D-Link Picture. It points the port 5190, in this case, to computer at 192.168.1.3 for the TCP Protocol.

Information Block

This site is about iChat from Version 1 through to iChat 5.x.x
Mostly this is kept as an Historical Document. Some small tense changes have been made but the content is by and large untouched.

It has a mixture of basic info and problem solving help.

The sections below will change for Specifics about info on the page on view

Options to This Page

To the right you can resize or colour the page as well as choose one of three Fonts.

About This Page

This picture shows what this Thomson-Alcatel Speedtouch modem has as the closest thing to Port Forwarding.

In this case there are effectively the same thing as the Thomson device does this for Packets as well as for Addresses.

This means in theory a port could be pointed to another one, such as inside (computer) 5190 to Outside (Internet) 433. We know this particular combo will work as the AIM oscar server seems to accept logins on any port. It partical terms this jiggery-pokery does not work.

Each port is laboriously set up one at a time to be entered needing 31 entries as some of the 29 ports iChat uses need TCP and UDP done separately.

Compatibility

Much of this page has been altered to be as HTML 5 compatible as possible. This may cause issues with any of the Browser below.

I have tested in Safari 18.1, Firefox 130.x and 131.0, Vivaldi 6.9.3447.48 and iCab 6.2.3 (All Mac Browsers) I don't have access to a PC let alone multiple browsers to test on.

Previously confirmed to work with Win/IE 5.5 and later (should work in 5.0, but not confirmed), Firefox 2, Safari 3, Opera 9, iCab 3.02 and later, Mac/IE 5, Netscape 6 and later

Old browsers (IE version 4 or earlier, Netscape 4 or earlier) may only see a text-based page which, while not the prettiest option, is still entirely usable.
