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.
