Configuring RealTick® to work behind
a firewall
Question:
How am I able to get RealTick® to work behind a Firewall?
Solution:
RealTick® can easily be configured to run behind a firewall
when two things happen. The first thing is to have the cooperation
of the Network Administrator to open certain ports on the firewall
itself, and the second is to make adjustments to the users TAL.ini
file.
Firewall Port Configuration:
In order for RealTick® to properly connect through a Fire Wall,
Ports 1723 - 1743 need to be opened. In some cases, port 1723 is
reserved for PPTP, so an additional port, 1838, will need to be
opened instead. To test if these ports are open, a telnet
test needs to be run to ensure that there is proper connectivity
between your PC and the TAL Data servers.
Telnet Made Easy:
Windows uses the Telnet Protocol, part of the TCP/IP suite of protocols,
to connect to a remote computer over a network. For our purposes,
a telnet test is nothing more than a test to determine if you are
able to establish a connection to the TAL Data servers. The telnet
method that Windows 95, 98, Me, and NT all use is the same. However,
with the release of Windows 2000, telnet has changed a little bit
so I will explain the procedures for each O/S.
Telnet in Windows 95, 98,
or Me
1. Click on the Start
button.
2. Click on Run.
3. Type telnet
and press Enter.
4. Click on the Connect
menu
5. Select Remote
System.
6. Enter 63.75.60.224
as the host.
(This is just one of several perms, prices,
or order servers that you can try.)
7. Enter the port
#
Telnet in Windows 2000
1. Click on the Start
button.
2. Click on Run.
3. Type telnet
and press Enter.
4. At the Telnet prompt,
type open 63.75.60.224 port
#
OR
1. Click on the Start
button.
2. Click on Run.
3. Type command
press Enter.
4. Type telnet
63.75.60.224 port #
A successful telnet session will show the host name in the title
bar when using Windows 95, 98, or NT. In Windows 2000, a successful
telnet session will show a very brief connection and then a flashing
cursor with no prompt. The port # 's that you should test are 1723,
1724, and 1838.
Try 1723 first to see if there is a conflict with PPTP. If you
cannot connect, then most likely there is a PPTP conflict. Try 1724.
If you can connect, add the following section and line to the TAL.ini
file:
[TALIPC]
UseNewPort=Y
Now test port 1838. If ok, then you should be able to log in to
RealTick®. If none work, the ports most likely are not open.
Confirm with the Net Admin
that these ports are open!!!
