2. Setting port forwarding on the router

To ensure that your specified SIP and RTP port numbers are used on the WAN inter-
face with the public IP address, you must define port forwarding rules for the SIP
and RTP ports on the router.
To define port forwarding on the router, proceed as follows:
The terms used in the following can vary from router to router.
To release a port, you must enter the following details (example):
Protocol
UDP
UDP
Protocol
Enter UPD as the protocol to be used.
Public port
Port number/port number range on the WAN interface
Local port
The SIP and RTP port numbers set on the phone.
In the new firmware version for Gigaset VoIP telephones, you can set a RTP port
range. In this case, you must also define corresponding port forwarding for this
range.
Local host (IP)
Local IP address of your phone in the LAN.
To enable the router to perform this port forwarding, the DHCP settings of the
router must ensure that the phone is always assigned the same local IP address –
i.e. the DHCP does not change the IP address assigned to the phone during opera-
tion. Alternatively, you can assign a fixed (static) ID address to the phone. However,
you must ensure that this IP address is not within the address range reserved for
DHCP and is not assigned to any other LAN subscriber.
