Configuring the external firewall
Configuring the BMC Remedy Mid Tier through a firewall
As shown in Figure 1-1, the web client connects to the mid tier server through a
standard HTTP connection. If the web server (on the mid tier server) is configured
on a certain port—the default for most web servers is 80—then you would need to
open that port for HTTP on this firewall. The web client request would then use
this port in its requesting URL. For example, if your web server is configured on
port 8080, you would use the following example URL request:
http://webServer:8080/arsys/home
The firewall would need port 8080 open for HTTP. No mid-tier-specific
configurations are needed for this connection through the external firewall.
Configuring the internal firewall
The mid tier server connects to the AR System server using a TCP connection. If
there is a firewall between the mid tier and the AR System server, you must allow
traffic through the firewall on the TCP port on which AR System listens.
To enable these connections through the firewall, you must configure the
AR System server and the mid tier to communicate on the proper ports, as
described in the following steps:
Step 1 In the Ports and Queues tab of the AR System Administration: Server Information
form, set the AR System server to use a specific TCP port.
Because you are configuring the mid tier to use a specific port, registering the
server with portmapper is optional.
For more information about the AR System Administration: Server Information
form, see the Configuration Guide, “Configuring AR System servers,” page 122.
Step 2 Ask your network administrator to open the port on which the AR System server
is listening on the internal firewall for TCP.
For more information about assigning a specific port number in the Server TCP/
IP Port field on the Ports and Queues tab, see the Configuration Guide, “Server
Information—Ports and Queues tab,” page 157.
Step 3 In the Mid Tier Configuration Tool, select AR Server Settings, and then set the
Port# field to the AR System configuration.
These settings allow the mid tier to connect to the AR System server, using the port
specified.
