Scott,
Here's some info I took from echlink's site on firewalls.
Also test node 9999 is good to go to.
Basic Information
EchoLink requires that your router or firewall allow inbound and outbound
UDP to destination ports 5198 and 5199, and outbound TCP to port 5200.
Source
ports are
dynamically assigned. If you are using a home-network router, you will
also
need to
configure the router to "forward" UDP ports 5198 and 5199 to the PC on
which
EchoLink is running.
This can be summarized as: Allow UDP (source port any, destination ports
5198- 5199) from Internet to PC
Allow UDP (source port any, destination ports 5198-5199) from PC to
Internet
Allow TCP (source port any, destination port 5200) from PC to Internet
The information above applies to every situation, regardless of the type
of
equipment and software you are using. If the information below does not
help you
solve the problem, please consult your equipment's documentation, or
contact the
manufacturer for support, and provide them with the information above.
Note: If you are using Internet security software and have recently
upgraded
to a newer version of EchoLink, you may need to re-apply the special
security settings
you had established earlier.
A useful Web site that discusses port forwarding, with solutions for
specific makes and
models of equipment, is www.portforward.com.
Microsoft Windows XP
Windows XP comes with a built-in "firewall" feature that helps
protect your computer from undesired connections from the Internet.
In order to use EchoLink, you will need to adjust some settings if the
built-in firewall is enabled.
There are two different versions of the Windows firewall, depending
on the version of Windows XP you are using. Verify the Windows XP
version by right-clicking the My Computer icon on your desktop, and
choosing Properties. Then, choose one of the links below:
Windows XP Service Pack 1: See Windows XP Firewall Setup. Also
see the Microsoft article Using the Internet Connection Firewall.
Windows XP Service Pack 2: See EchoLink and Windows XP SP2.
Windows Internet Connection Sharing
Several versions of Microsoft Windows support a utility called
Internet Connection Sharing (ICS). This utility allows several
different computers on a local network to access the Internet over a
single connection. Basically, ICS is a software-based router. As
with any router, the software must be configured to "forward" UDP
ports 5198 and 5199 to the computer on which EchoLink is installed,
which might not be the same computer on which ICS is running.
A useful utility for setting up Internet Connection Sharing is ICS
Configuration.
See also the Microsoft articles on troublehooting ICS problems and a
description of ICS.
Home-Network Routers and Modems
A "router", as used in a home network, is a device which allows
several different computers to share a single connection to the
Internet. A router is frequently used in conjunction with a cable
modem or DSL connection. Popular models are manufactured by
Linksys, D-Link, and SMC. We do not have configuration information
for any routers other than those listed below. If your model is not
listed below, please consult the manufacturer's documentation for details.
Finding the Local IP Address
To configure your router, you will first need to know your computer's
local
IP address. If you are not sure what the address is, do the following:
Windows 95, 98, and Me: From the Start menu, choose Run, and enter
winipcfg. The IP Configuration window should open. In the drop-down box
at the top,
select your Ethernet adapter, then note the IP address that is displayed.
Windows NT, XP, 2000, and 2003: From the Start menu, choose
Programs->Accessories->Command Prompt. A command prompt should
open. Enter ipconfig. Note the IP address that is displayed underneath
the
name of your
Ethernet adapter.
Linksys Routers
Using a Web browser, bring up your router's configuration page.
By default, the URL is 192.168.1.1, the user name is blank, and the
password
is "admin".
Be sure you are using the latest version of the firmware for this device.
The version of your current firmware is displayed on the Setup page.
Check
the Linksys Web
site for details. Click the Advanced tab. Click the forwarding tab.
If you see a column labeled "Customized Applications" on the left, enter
"EchoLink" on the first line. (Not all versions of the Linksys firmware
have this
column.)
In the first pair of Service Port Range (or Ext.Port) boxes along the top,
enter 5198 and 5199.
On the same line, under Protocol, choose UDP (or check the UDP box). On
the
same line,
enter the local IP address of the computer running EchoLink. (If you are
not sure what the address is, run "winipcfg" or "ipconfig" from a command
prompt).
If there is an Enable check box on the same line, check it.
Click Apply to save changes.
