DHCP on Vigor 130 & Airport Extreme was created by jackw

I use a Vigor 130 to connect to BT Infinity and use an Airport Express for the LAN.

Is it better to allow the Vigor 130 to handle DHCP and NAT, and disable it in the Airport, or to let the Airport do this and disable it in the Draytek? Would either approach have an advantage in terms of security, speed or convenience?

Thanks for any advice.

The Vigor 130 is a modem only.

From the quick start guide :

The Vigor 130’s primary function is as a transparent bridge modem for
xDSL services – not as a router/firewall in itself. It connects a secondary
router or other device to your DSL line, where that device does not directly
support DSL itself.

As a bridge, the Vigor 130 only provides the physical conversion from
xDSL (ADSL or VDSL) to Ethernet and all firewalling, routing or other
advanced routing functions are managed by your secondary device (a
separate router, firewall etc.). The secondary device may also be a single
PC, a PC-based software router or an Apple Airport™ type device.

The Vigor 130 comes preconfigured for most UK ISPs. Therefore, in most
cases you do not need to perform any setup of the Vigor 130 at all. You only
need to physically connect it (plug it in) and then configure your connected
router/firewall. Your ISP username and password go into your router, not the
Vigor 130, which just acts as the DSL-to-Ethernet bridge.

Thanks for the reply. Yes I've seen that in the QSG, but the Vigor 130's setup does include a page for enabling or disabling DHCP and NAT. My Vigor 130 came with DHCP & NAT enabled (using addresses in the 192.168.1.n series) the Airport Extreme also offers DHCP & NAT (in the 10.0.1.n series). So, what I want to know is which one is it better to use, or if it makes no difference.

The only thing I changed in the Vigor 130 is the DNS addresses. I would leave everything else alone unless you run into problems.

I connect to a BT based FTTC service and my router is an Asus RT-AC3200,I simply had to plug in and everything worked fine.
