====== Multiple DHCP-Server instances ====== Having multiple DHCP-Servers running is very useful if you're dealing with VLAN's, [[howto:use_cases:wireless:guest_ap|Guest AP]] or any kind of separating networks from another. To give each Network a different configuration of IP-Addresses, Netmasks or any settings which are provided to the clients by the DHCP-Server.\\ ===== Overview ===== ==== Level of difficulty === Medium ==== Related topics ==== * [[documentation:configuration:UCI]] * [[documentation:configuration:config_files:config_dhcp|/etc/config/dhcp]] ===== Instructions ===== ==== GUI ==== Not available, yet ==== UCI Config System ==== * **Add DHCP instance** <code> uci add dhcp dhcp uci set dhcp.@dhcp[-1].inderface=guest uci set dhcp.@dhcp[-1].start=62 uci set dhcp.@dhcp[-1].limit=192 uci set dhcp.@dhcp[-1].leasetime=600h </code> __Note:__ The option interface defines on which interface the dhcp-server is listening for dhcp-requests. * **Store changes** <code> uci commit </code> * **Apply changes** <code> /etc/init.d/dnsmasq restart </code> ==== UCI config files ==== The 'dhcp' options are stored in [[documentation:configuration:config_files:config_dhcp|/etc/config/dhcp]] * **DHCP instance** <code> config 'dhcp' 'guest' option 'interface' 'guest' option 'start' '62' option 'limit' '192' option 'leasetime' '600h' </code> __Note:__ The option interface defines on which interface the dhcp-server is listening for dhcp-requests. * **Apply changes** <code> /etc/init.d/dnsmasq restart </code> ===== Troubleshooting ===== Not available, yet
