When PPTP local tunneling is used a local network client initialises a PPTP tunneled PPP connection VPN to Nokia M1122 The modem Copyright Nokia Networks Oy C33906002SE_00 NOKIA terminates the tunnel and all data from that terminated local PPTP tunnel will be forwarded to an assigned ATM VCC by using PPP over AALS encapsulation Thus each local PPTP tunnel requires an equivalent ATM VCC assigned to it restricting the total number of local PPTP hosts to 8 Local tunneling is used when there is a need to have one or more computers connected independently to different networks For example in remote work application the rest of the family may be using the common ISP services and one or two family members need to gain access to their corporate networks With local tunneling these remote workers may be connected to a different network than the rest of the users Local tunneling is activated using the PPTP client running for example in Windows The destination IP address must be M1122 LAN VBRIDGE IP address depending on the configuration PPP packets within PPTP are mapped to the configured VCC M1122 has three different ways to choose the ATM VCC that will be used for tunneling e Automatic chooses the first free VCC e Chooses the VCC number using C number where number is from 1 to 8 C number is fed after the M1122 IP address see Figure 16 e Chooses the VCC number using N name where name is the description N2. lt Receive data 2 Rx lt Receive data 3 TX gt Transmit data 6 Tx Transmit data Table 1 Ethernet interface pin out numbering 1 6 UUUUUU Figure 18 DSL connector PIN Signal 3 DSL1 4 DSL2 Table 2 ADSL interface pin out numbering M1122 User Manual 5 2 26 Ambient conditions EMC and safety Ambient conditions Operating temperature range 5 to 45 C Humidity 10 to 90 non condensing EMC M1122 complies with the following specifications provided that the device is connected to an earthed socket outlet Emission EN55022 1998 class B Immunity EN55024 1998 EMC EN300386 2 1997 Overvoltage ITU T K 21 Safety Safety EN60950 NOKIA C33906002SE_00 Copyright Nokia Networks Oy 27 M1122 User Manual

The mode in which M1122 operates depends on the configuration of the unit s interfaces LAN interface LAN interface can be configured to bridge and route packets There are three different operational modes in the LAN interface e Bridging only only bridging is activated in the interface In this case the interface bridges all protocols e Routing only only IP address is configured in the interface In this case the interface routes IP packets e Bridging and routing Bridging 1 activated in the interface and IP address is configured in the interface In this case the interface routes IP packets and bridges all other packets Internal host gateway interface There is a special host gateway logical IP interface within M1122 called VBRIDGE This interface has a specific purpose in M1122 In applications where some ATM virtual channel connections are used for bridging IP traffic and some other ATM virtual channel connections are used for routing IP traffic the VBRIDGE interface must be used instead of LAN IP addresses Alternatively this interface is used in bridge only application when the IP address is required for remote management purposes Data VCC operation M1122 supports the following encapsulations in each ATM data virtual channel individually e RFC2684 LLC encapsulation for bridged IP ETH LLC e RFC2684 LLC encapsulation for routed IP IP LLC C33906002SE 00 Copyright Nokia Networks Oy 17 M1122 User Manual
6. Address Port Translation M1122 supports Network Address Port Translation NAPT for TCP IP UDP IP and ICMP IP protocols When is used a single IP address is allocated to a VCC which leads to the public IP network The Ethernet subnet has private IP addressing and is not visible to the VCC NAPT translates the IP source address and source port number dynamically to the VCC IP address and port number Similarly packets coming from the VCC are mapped back to the original destination addresses NAPT allows up to hundreds of hosts to share a Copyright Nokia Networks Oy C33906002SE_00 NOKIA single VCC IP address to the public network The principle of Network Address Port Translation is presented in Figure 15 Home network LAN Internet WAN src 192 168 1 112 1228 dst 194 112 11 111 80 src 195 112 12 161 50001 dst 194 112 11 111 80 NAPT router src 194 112 11 111 80 lt dst 192 168 1 112 1228 src 194 112 11 111 80 lt dst 195 112 12 161 50001 192 168 1 254 195 112 12 161 Figure 15 Principle of Network Address Port Translation NAPT may restrict the operation of some IP applications NAPT also operates as a simple IP firewall because translation is only allowed when the first packet is transmitted from the LAN This means that the NAPT table entry is created only when a packet is sent from the home network to the Internet With server support capability the user c
