SESSION BORDER CONTROLLER 3 Setting up IP address distribution in a LAN 1.1 Need You would like to adapt IP address distribution in your network (LAN) according to your needs. 1.2 Description When your router is delivered (with factory settings), IP address distribution in your network (LAN) is managed in accordance with the standard concept, including a DHCP server. These settings can be adjusted by an expert. Swisscom (Switzerland) Ltd 1.3 Requirements/limitations Requirements: Swisscom contract: My Office or Business Internet light CB firmware version 07.06.02 or higher You must be logged into the router portal Limitations: You use static IP addresses for all LAN ports 1.4 Diagram Diagram corresponds to standard configurations Internet Swisscom Network Router Swisscom Services Security Distribution Devices Static IP Copper SERVER Mobile ETHERNET SWITCH IP-Adress of DHCP-Range 192.168.1.2-.32 Internet Backup ISDN ISDN Fiber SG/ 1 2 3 WAN/ 4 192.168.1.33-.127 IP-Adress of DHCP-Range with Device Separation 192.168.1.128-.254
Swisscom (Switzerland) Ltd 4 1.5 Standard settings for DHCP address distribution Under Settings, Network, choose the Basic Settings tab. Under Network Settings and IP Address Distribution, you will see the current IP settings of your router. When the router is delivered (factory settings), the IP address distribution settings are as follows. The router s IP address is 192.168.1.1 and the subnet mask is 255.255.255.0. This means that the router can address 253 devices in your network (LAN). The DHCP server of the router is enabled. The IP addresses 192.168.1.2 to 192.168.1.32 are earmarked for static IP addresses that can be permanently assigned to a device in the network (LAN). The IP addresses 192.168.1.33 to 192.168.1.127 are earmarked for dynamic IP addresses and are assigned by the DHCP server of the router. The IP addresses 192.168.1.128 to 192.168.1.254 are designed for IP telephones (VoIP) used in the LAN. See also Advanced Settings. The address ranges 192.168.11.x and 192.168.13.x are blocked for use in the LAN. These addresses are reserved for the Guest WLAN, for example. Swisscom recommends that you do not adjust the standard settings where possible. 1.6 Changing IP address distribution Under the Basic Settings tab, you can adapt IP address distribution for your network (LAN) according to your needs. Network Settings: Here you can determine the router IP addresses for your network (LAN). With the subnet mask, you can determine how many IP addresses are available in your network. IP Address Distribution: Enable or disable the DHCP server of the router Adjust the range of dynamic IP addresses, start and end of distribution range Adjust the IP address of the router (gateway)(normally identical to the IP address of your router)
Swisscom (Switzerland) Ltd 5 When you have adjusted your settings, finish the process by clicking on Save. 1.7 Advanced settings Under Settings, Network, Basic Settings, you can enter additional DHCP settings by clicking on Advanced. 1.7.1 Static IP address distribution Under Add Static Lease, you can assign an IP address from the dynamic IP range of the DHCP server to a device such as a printer, for example. To do this, enter the MAC address of your device and the required IP address and click on Add. Save the setting by clicking on Save. As soon as the device registers with the network (LAN), the defined IP address will be assigned to it.
Swisscom (Switzerland) Ltd 6 1.7.2 VoIP end device separation By separating (separate IP range) VoIP and Internet traffic, it is possible to reduce jitter (phase noise) and thereby improve voice quality. Under VoIP IP Address Distribution, enter the first six characters of the MAC address of your VoIP telephones, e.g. Aastra telephones, in the OUI field. Each manufacturer has a different MAC address. Depending on the number of VoIP end devices, define the distribution range for each MAC address under Range Starts at IP Address and Range Ends at IP Address. Save the settings by clicking on Save. If you now connect a VoIP telephone of the defined manufacturer to your network (LAN), a corresponding IP address will be assigned to it.
