Cannot connect to all iChat users.

Hi,

I have the exact same problem which I've posted here a number of times. Ralph always gives me the links to the fix, but most of the explanation seems to be over my head. How, for example, do you actually CHANGE the ports? How do you actually ADD the multiple numbers?
I have one person I can NOT connect with, but he connects with others who I can also connect with. Latest versions, etc.

Rick,

Sometimes I wonder at the patience of those who try and help us . . . you haven't looked very hard at Ralphs pages, have you? If you look on the left of any one you'll see what topics the various pages cover. If you look at Page 4 (Eliminating Router Problems) you'll find exactly what to do and, brilliantly illustrated, how to do it: i.e. System Preferences->Sharing->Firewall Tab->New Button->Select 'Other' from the list . . give it a description . . . and he shows how to copy and paste in the required port numbers. And if, having once done this, you later realise you need to make a change, don't forget to select (highlight) your created one in the list of services (your description) shown under the Firewall tab pane. It will be at the bottom of the default ones and checked.

Good luck!

HI Rick,

Most modems have Port Forwarding (it is the oldest and most common method of Opening ports).

It can be in different places in different modems.
To set up iChat it is most likely in something called Virtual Server, NAT or Port Forwarding. This ccan be inside this of the same names or inside a menu item called LAN Set up or on Linksys it is in Games and Applications.

Port Triggering is normally close by or devices that also have this.

UPnP als gets put in different places. At http://portforward.com/routers.htm (which may help you to identify your type of dvice and show you set up pics) I have seen UPnP have it's own menu item.

On Linksys you wnat the version in Administration. On my Thomson Alcatel Speedtouch 510v4 it is NAPT which in turn in is ADvanced.

Broad options.
Open Advanced
Look in LAN IP Set Up, or NAPT, Virtual Server, Pin holes and sometimes Firewall. (firewall can mean something different)
Also check items that say Applications and Games

Posting which modem or router you have will help.

Also check March 4th in My Blog for trigger ports http://www.aptr36.dsl.pipex.com/200503_01_ralphjohnsarchive.html

NOTE: Not all devices can have the Triggers set up like this (adding all the triggered ports with just commas) If that is the case do it as so.

Trigger 5678 on UDP to Trigger port 5060 on UDP
Trigger 5060 on UDP to Trigger ports 16384-16403 (Dashes are allowed) or it might say start and end ports.
