====== DHCP-Server on the external interface (EXTIF) ======

!!Note: AstLinux 1.1.1 or later is required!!

There is a simple way to use dnsmasq as a DHCP-server on the external interface (EXTIF), or if you have only one NIC (e.g. in a VM), you need to add the following variable in your ''user.conf'':

  EXTDHCP="yes"

If you need a different DHCP range than the default (100-220), you also need add it to your ''user.conf'' as usual e.g.:

  DHCPRANGE="10:120"
 
If you need other DHCP values that differ from the defaults((look at the "dhcp-option" values in "/etc/dnsmasq.conf" in the System Tab)), you can add them as usual in ''dnsmasq.static''. Example:

  dhcp-option=ext,option:ntp-server,192.168.30.10

**Firewall**

If you use the firewall (AIF), you'll need to open the respective ports for the services you'd like to allow\\ 
(e.g. TFTP, NTP) with "Pass EXT->Local". DHCP traffic is automatically allowed through the EXTDHCP variable.

!!Note ->!! If you require this feature for an older version of AstLinux, there is also another more **[[userdoc:tt-ext-dhcp-server-old|complicated way]]**.
