About DHCP Server
When enabled, Untangle's DHCP Server will hand out dynamic IPs to hosts on your network. The Current DHCP Entries list shows you the current DHCP leases. You can use the Static DHCP Leases area to add a Static DHCP lease for a host - this will make Untangle always give the specified MAC address the same IP. Here is a list of the DHCP Server's options and what they do:
| Setting | Description |
|---|---|
| Enabled | Enables or disables the DHCP server. Please note, if the DHCP server is disabled it will not hand out DHCP to any interfaces. |
| Start | Sets the start of the DHCP address pool range, for example 10.0.0.100. |
| End | Sets the end of the DHCP address pool range, for example 10.0.0.200. |
| Lease Duration | Sets the duration of DHCP leases in seconds. |
| Gateway | Sets the Gateway given out to DHCP clients. You can leave this blank and Untangle will hand out the proper gateway on each non-WAN interface you have enabled DHCP on. |
| Netmask | Sets the Netmask given out to DHCP clients. You can leave this blank and Untangle will hand out the proper netmask on each non-WAN interface you have enabled DHCP on. |
| Lease Limit | The maximum number of simultaneous DHCP leases. |
| Authoritative | Makes Untangle's DHCP server the authoritative server on the network. It changes the behaviour from strict RFC compliance so that DHCP requests on unknown leases from unknown hosts are not ignored. |
Advanced Setup
You can pass specific options to dnsmasq, Untangle's DHCP/DNS server, at Config > Networking > Advanced > DHCP and DNS. Each option should be on a separate line.
