8.3. Some methods to deal with NAT routers and firewalls
Problems arise when the desired connection has to go through a NAT router, and/or a firewall, that
blocks a direct IP communication.
This is a very common issue, especially if one needs to set up a transfer via the Internet. It is impossible
here to describe in details the possible ways to deal with this problem, but the following just shortly
discusses some typical solutions. Most probably, a network administrator should be consulted for
support, and for granting adequate network authorisations and/or privileges.
The most classical issues are related to:
The presence of a NAT router on the network path between the codecs.
The presence of a firewall on this path.
It is always important to have available the information regarding the network organization and to be
allowed to access the devices which need to be configured. Hence we highly recommend to involve the
persons empowered for such tasks.
8.3.1. Links via a private network
No special problem should be met within a LAN. The operation is also possible with codecs from other
manufacturers, provided that they comply with the Tech3326 EBU recommendation (also known as
"N/ACIP" recommendation). However you should check for specific settings or preparation possibly
needed on such devices.
A wide area network covers a wider geographic range, and the network topology most probably
includes routers on the path between the codecs to be linked. However, usually there is not much
difference with a local area network.
Note: using a VPN leads to just the same case; the operation is identical as far as the codecs are
concerned.
8.3.2. Links through a public network (Internet)
If each of the units has got a "direct" access to Internet with a public address, we are in the same
situation as the previous one, functionally speaking (private WAN). The addressing scheme is normally
static, as DHCP can rarely be used on a public access. In fact, this situation is very seldom met in the
field!
First, the Internet access is usually protected by a firewall which will, as a principle, block a priori the
desired connection. In such case exceptions (to the firewall security rules) must be created, that will
allow this connection; this has to be done by the person in charge of the network management.
Most often, on one access if not both, the codec accesses the Internet via a NAT router. This router
shares Internet access, with one or a few public addresses, among the equipment on the LAN. On this
LAN the devices get local private addresses, and the router carries out an IP address translation. Note
that:
As an example, a consumer ADSL modem-router is almost always a NAT router, sharing a single
public IP address between the devices connected to the router.
It is just the same on a 3G/3G+/4G mobile IP access; the terminals (phones or computers) access
the Internet via NAT routing.
NAT routing is often included in the firewall features; in fact NAT routing somewhat participates
to the protection against direct attacks from the outside.
