Port Security Reference Guide
This document details the use of TCP/IP/UDP ports throughout the SCOPIA Solution, organized by
product name.
Each port entry includes a description of the protocol used by the specific port, the role that the
port serves, the direction of traffic through the port (in, out or both), and the results of blocking
the port on the firewall.

The number of ports ECS needs for this
purpose is the maximum calls allowed by
your license multiplied by four.
To limit ECS’s use of ports within the range
of 1024-5000:
1. Close ECS.
2. Open the registry.
3. Navigate to HKEY_LOCAL_MACHINE\
SOFTWARE\RADVISION\
Enhanced Communication Server\
Storage\Config\Stack
4. Create a new key of type REG_SZ called
PortMin. Give it the value of the
minimum port number ECS should use.
5. Create a new key of type REG_SZ called
PortMax. Give it the value of the
highest port number ECS should use.
6. Restart ECS.
There may be other applications on the
same computer which altered the global
maximum port for all processes running on
that Windows PC. Verify this global
maximum is unchanged in the
HKEY_LOCAL_MACHINE\
SYSTEM\CurrentControlSet\Services\

SCOPIA PathFinder
SCOPIA PathFinder is SCOPIA Solution’s answer to firewall traversal. The SCOPIA PathFinder
Server is an H.460 server, usually located in the DMZ, while the SCOPIA PathFinder Client is an
H.460 client, typically located outside the enterprise firewall with the H.323 endpoint (Figure 1-1
on page 15).
Many recent H.323 endpoints have built-in H.460 functionality, thereby avoiding the need for a
SCOPIA PathFinder Client.
If an H.323 endpoint located in a partner company does not have H.460 capabilities, it must
communicate via the SCOPIA PathFinder Client to access the SCOPIA PathFinder Server in the DMZ
(Figure 1-1 on page 15).
Note: There must be no firewall between the H.323 endpoint (entity) and the SCOPIA PathFinder Client.
An H.323 endpoint in the public domain can also directly dial the SCOPIA PathFinder Server using
direct port access (ports 4000-5000 in the tables below).

Note: When an H.323 endpoint (or other H.323 entity) within the enterprise connects to the SCOPIA
PathFinder Server in the DMZ via the internal firewall (Figure 1-2 on page 18), you need to install
a SCOPIA PathFinder Client within the enterprise, or use H.460-enabled endpoints. Otherwise you
must open the internal firewall to the SCOPIA PathFinder Server (1024-65535).

Note: As mentioned above, if there is a firewall between the H.323 client and the SCOPIA PathFinder

firewall between the endpoint and the SCOPIA PathFinder Client.
