========================
IF YOU'RE BEHIND A FIREWALL
If your computer is running on a corporate LAN inside
a firewall, you might not be able to connect to Palace
sites outside the LAN unless your network
administrator changes the firewall configuration. This
section describes the necessary firewall changes.
If you have problems connecting, show this section to
your network administrator.
Two firewall changes are necessary to allow Palace
users inside the firewall to connect to Palace servers
outside:
1. Permit the establishment of TCP/IP connections on
a particular port (usually 9998).
2. Permit incoming packets on that same port over
established connections.
Descriptions follow.
Permitting TCP/IP Connections over a Port
The Palace uses TCP/IP to establish a reliable
connection to a PalaceServer that is listening on a
particular port. When you connect, you specify the
name of the server (such as welcome.thepalace.com) and
the port (usually 9998). The port can vary from server
to server, but most use the default port of 9998. The
Palace then sends a TCP/IP message to establish
connection over that port to the PalaceServer.
However, firewalls often prevent communication over
all but a few well-known ports. Therefore, to allow
The Palace to make contact with servers, the network
administrator must configure the firewall to permit
internal workstations to establish TCP/IP connections
on the specific port (usually 9998).
Permitting Incoming Packets Over the Same Port
Once the Palace establishes a connection to the
server, the two send packets back and forth over the
Palace port (again, usually 9998). However, firewalls
often prevent incoming packets from other than well-
known ports. Therefore, the network administrator
must configure the firewall to permit incoming packets
over the specific port (usually 9998) on established
connections.
The key to permitting incoming packets is that the
firewall should not allow them except when the
connection has already been established by an internal
workstation. This minimizes the security risk of
hackers trying to break into the LAN, because someone
inside must establish the connection first.
In addition, the firewall must be configured to allow
outgoing packets over the specific port on established
connections. However, this usually happens as a result
of permitting TCP/IP connections over the port.
NOTE: In LANs where clients are not directly connected
to the firewall but instead are connected to a proxy,
the network administrator might need to perform
additional configuration steps to allow packets
through on these ports.
