Glossary
Static IP address
A static IP address is assigned to a network component manually during net-
work configuration. Unlike a
change.
STUN
Simple Transversal of UDP over NAT
NAT control mechanism.
STUN is a data protocol for VoIP telephones. STUN replaces the private IP
address in the data packets of the VoIP telephone with the public address of the
secure private network. To control data transfer, a STUN server is also required
on the Internet. STUN cannot be implemented with symmetric NATs.

of the network number part is determined in the subnet mask. In the subnet
mask 255.255.255.0, for example, the first three parts of the IP address are the
network number and the last part the subscriber number.
Symmetric NAT
A symmetric NAT assigns different external IP addresses and port numbers to
the same internal IP addresses and port numbers – depending on the external
target address.
