    Security/Filter Defines The Express 4100/4110 can filter packets based on certain parameters within the packet. The method used by the Express 4100/4110 allows the highest flexibility for defining filters and assigning them to a Connection List profile. The filters are set up in two steps: (1) defining the packet types, and (2) adding them to a list under the Connection List profile.

  • Page 86: Configuration/Connection List

    Chapter 3. Terminal Menu Operation and Structure Configuration/Connection List The Express 4100/4110 uses the Connection List to specify the profile each user or group of users are to have when connected. Each profile or item in the Connection List has many configurable parameters giving high flexi- bility on a per user basis.

  • Page 87: Connection List/Description

    • • When answering a call, the Express 4100/4110 does not know who the PPP peer is until the authentication phase is completed. Two PPP protocols (EAP and CHAP) require the authenti- cator to transmit a username which the authenticatee uses to cross reference the password to use.
  • Page 88 When Configuration/Security/Authentication is set to Radius, authentication is performed by the RADIUS server. The Express 4100/4110 uses the DEFAULT Connection List pro- file for all other parameters not supported by RADIUS attributes. RADIUS attributes currently supported are: framed ip, framed netmask, framed ipx network, framed routing, framed compres- sion, and idle timeout.

  • Page 89: Authentication/Tx Method

    Authentication/Tx Method Write security: 2; Read security: 3 This parameter specifies how the Express 4100/4110 is to be authenti- cated by the PPP peer. There are four possible selections. See “Security/ PPP” on page 3-31 for an explanation of the three PPP standard authenti- cation types.

    Ethernet side can access the Internet simultaneously. See the sec- tion “IP/NAT” on page 3-18 for more global options. Setting this option to On will cause the Express 4100/4110 to perform NAT. In the Off (def) position, the unit will route across the connection normally.

  • Page 92: Route/Private

    Route/Force IP Write security: 3; Read security: 5 When set to Yes, the Express 4100/4110 will force the PPP peer to use the IP address in the IP/Net for this profile as its WAN IP address. Normally this is set in the No (def) position.

    This is usually referred to as being a “half-router.” However, a PPP peer which wants to assign a network address to the WAN link can do so, in which case the Express 4100/4110 will go into “full-router” mode.

  • Page 95: Ipx/Type 20 Packets

    IPX networks. The Type 20 IPX packet is used specifically for this purpose. This causes special handling of this packet by the Express 4100/4110. When a router receives this type of packet, it rebroadcasts it across all interfaces except the one it is received on and includes the network number of that interface in the data portion of the packet.

  • Page 96: Connection List/Probe

    However, some routers could wait until their regular RIP or SAP time period has been reached before they advertise their routes or services to the Express 4100/4110. The value is in seconds and ranges from 5 to 180. The default is 5 seconds and assumes that a routing update is received upon connection.

Multilink/Fragment Write security: 3; Read security: 5 When this item is set to Yes (def), the Express 4100/4110 will split outgoing packets greater than 128 bytes into two Multilink frag- ments and simultaneously transmit them one per B-channel. The receiving PPP peer will then reassemble them.

  • Page 98: Ppp/Compression

    PPP/VJ Compression Write security: 3; Read security: 5 When this item is set to On, the Express 4100/4110 will perform TCP/IP header compression known as Van Jacobson compression to the PPP peer. Normally, this is not necessary over ISDN connections and can be set to Off (def) to disable it.
