Answer![](/consumers/img/s.gif) | Just as the WAN interface of the SBG6782 can be configured for a customized setup, the SBG6782 also includes configurable options for the Local Area Network (LAN). The LAN IP Address and DHCP range can be configured and modified to suit the needs of the network. By default, the LAN IP address of the SBG6782 is 192.168.0.1. This document describes how to change the LAN IP address and DHCP range of the SBG6782.
NOTE 1: If the LAN IP address is modified to be in a different subnet (e.g. 192.168.5.1), the SBG6782 will automatically change the DHCP range to use addresses in that subnet.
NOTE 2: The subnet mask of the SBG6782 (255.255.255.0) cannot be modified.
Changing the Local Area Network (LAN) IP Address
- Launch a Firefox or Safari browser.  Enter http://192.168.0.1 into the address box, and press the Enter key. Â
NOTE: A browser message on Chrome, Edge, Firefox, and Opera, may appear when accessing the Web Manager. Â The message includes 192.168.01 uses an unsupported protocol and ERR_SSL_VERSION_OR_CIPHER_MISMATCH. Â The Web Manager uses an earlier version of the TLS protocol and does not match the version allowed by the web browser. Â Safari browsers on Apple PC and mobile devices are not impacted. Â The workaround to access the Web Manager with a PC is to use the Firefox browser and set the TLS version to 1. Â For workaround instructions refer to article #Â 19435 - 192.168.0.1 uses an unsupported protocol. Â - A security or private risk alert may appear on the web browser advising users to proceed with caution when accessing the Web Manager. Â There is no risk in proceeding to the Web Manager. Â For instructions to bypass the alert screen, refer to article #Â 18181 - Alert Message for Web Manager Access.
 - On the Login page, enter admin or a customized username in the Username field.

- If it is desired to have the SBG6782 give IP addresses to all of the devices automatically, leave this setting at yes.
- If some devices are manually configured with IP addresses, but others are to receive an address from the SBG6782, leave this setting at yes.
- If there is another device on the network that will be the DHCP server, change this setting to no.
- If it is desired to manually configure each device with an IP address, change this setting to no.
NOTE: If the DHCP Server option has been set to no, skip down to step 8.  - Starting Local Address - This setting classifies the first IP address to be used in the DHCP range.
- Max Number of Network Devices - This will classify how many IP addresses are to be used in the DHCP range. For example, if this option is set to 100, and the Starting Local Address is set as 192.168.0.100, then the DHCP range will be from 192.168.0.100 - 192.168.0.199.
- Lease time - This is the number of seconds that a device will keep an IP address if that device has received an IP address automatically from the SBG6782.
