Nefsis Video Conference Traffic Routing
The material below covers customer configurations for Nefsis online services; and dedicated,
on-premise video conferencing servers.
All Nefsis web and video conferencing server configurations traverse firewalls and proxies, for multipoint,
business-to-business online meetings. In all setups, Nefsis firewall and proxy traversal makes it easy to connect with
external offices, customers and vendors, via the public Internet and external corporate networks over which you
generally have little or no control.
confirm Nefsis has the video conferencing,
web conferencing, and online meeting features
that you require, we recommend taking the free trial. The free trial uses the default
Nefsis Online Service
configuration, which is easy to activate and the most popular configuration.
We also offer
Nefsis Dedicated, on-premise, installable
server software. For a free trial of Nefsis Dedicated, you must contact us.
Nefsis Dedicated: Server Routing & Access
The following configurations refer to Nefsis Dedicated, on-premise video conferencing servers. Nefsis Dedicated
is available for customers that require more routing, security, or other IT controls not available in standard online services.
When considering where to place the Nefsis server, it is important to note that the Host, Presenter, and all Participants must
have IP routing access to the server. This is true whether you are restricting the video conferencing server to internal-only
participants, or using it for general purpose web and video conferencing over the public Internet.
Nefsis video conferencing servers require ports 80 and 443 to be open and dedicated to the conferencing application. The
conferencing server defaults to a short list of additional ports, and listens to them all. We strongly recommend leaving the
default port settings as is, the default port list was developed over several years of production use in a wide variety of IT
environments. Please contact Nefsis technical support for additional details regarding
For customers that place the conferencing server behind a firewall, the ports mentioned above must be open. The firewall settings
must allow inbound and outbound traffic, and must allow ActiveX. In addition, the firewall must be configured to allow TCP sockets
to stay active long enough for the 'keep alive' packets to reset the timer in the firewall. Extra special care is required
when making these settings so that they apply to the specific conferencing server, IP address, and ports only, thereby protecting
border security policies.

The list below covers the most typical setups for Nefsis web video conferencing servers.
Behind Firewall (Open Ports To VideoConference Server)
In this configuration, the videoconference server is behind the firewall, with ports 80, 443, and a short list of additional ports
(see admin console) open to/from the conference server. The Nefsis server cloud and access point services (for external hosts and
participants) are still used.
This configuration is similar to that shown below. Note, however, that placing videoconference servers in the DMZ is considered
a better choice for a variety of reasons. Contact us for details.
RECOMMENDED FOR ON-PREMISE SERVER INSTALLATION:
Video Conferencing Server in the DMZ
Installations that plan to host the Nefsis video conferencing server in their own environment may consider placing the server in a
DMZ, so it does not violate the security policy of the corporate network. In this scenario employees are routed to the conferencing
server via a private IP address, while external participants use a public address.
The benefits of this approach are more routing options, performance, and security controls. In addition, there are more admin
console and feature-level controls available in the on-premise version, that are not exposed in a standardized online service. These
additional benefits require software licensing, CAPEX (sever), server installation, and network configuration changes.
Behind Firewall (No Open Ports to Server)
This is a LAN-only configuration. Although it was offered in earlier versions, it is no longer available.
the standard configuration:
Nefsis Online Services
This is the most standard configuration. It is the
easiest to implement, lowest cost, and most popular choice.
As with most online services, it involves no server installation or maintenance.
This configuration is ideal for customers that wish to implement
secure video conferencing without capital expenditures (CAPEX), and for those that seek to implement business-to-business
desktop, and desktop-to-boardroom video conferencing without any changes to their existing network infrastructure
. Note: Conference rooms must have a computer and Internet access.
This configuration is also used by customers that do not have the IT staff or infrastructure to implement one of the
configurations listed below; or intend to have large, recurring conferences that need more bandwidth at the server than
is available on in-house networks.
