Networks & Services
On this screen you can set the MultiAccess protocol services. Protocols make ongoing administration easier.
You will define data traffic as it travels the networks (e.g., the Internet). A service protocol setting consists of a
Name, the Protocol, the S-Port/Client (source port), and the D-Port/Server (destination port).
When entering the ports, you can enter a single port or a port range separated by a colon (:).
For AH and ESP, the SPI is a whole number between 256 and 65536, which has been mutually agreed upon
by the communication partners. The Internet Assigned Numbers Authority (IANA) reserves values below 256.
Notes:
•
TCP & UDP allow both protocols to be active at the same time. Any causes the MultiAccess to accept
any protocol offered.
•
The ICMP protocol is necessary to test network connections and MultiAccess functionality, as well as for
diagnostic purposes. In the Packet Filter > ICMP menu you can enable ICMP Forwarding between
networks, as well as MultiAccess ICMP reception (e.g., to allow ping support).
•
The ESP protocol is required for Virtual Private Network (VPN).
•
The AH protocol is required for Virtual Private Network (VPN).
There are options for editing or deleting the user added services. However, there are some standard services,
which cannot be edited or deleted. If the Packet Filter rules, SNAT, or DNAT uses the service, it cannot be
deleted. For editing any user-defined service, the Edit button has to be clicked to get the fields corresponding
to the service entry. The entries can be saved using the Save button.
