Do you mean DHCP on the WAN side or LAN side?

If DHCP on the LAN side, you can leave it enabled, set the scope to 100~
150, and that still leaves you with almost 200 addresses you can use in
a fixed IP mode on the LAN side.

If you set the LAN IP Subnet to 192.168.10.0/24, with the router at
192.168.10.1

you could set the first server/device with a fixed IP at:

IP 192.168.10.10
MSK 255.255.255.0
GW 192.168.10.1

DNS1 192.168.10.1
DSN2 Your ISP DNS1
DNS3 Your ISP DNS2

If you have a DSN server in your LAN, you would set DNS 1 to it, and
assuming that it has DSN Forwarding enabled, you would not need DNS 2/3.

As for the defaults on the WAN, almost every DSL connection I've setup
has required a FIXED MTU of around 1400~1430 in order to be stable. The
only unstable DSL connection we've ever seen was from a company called
Adelphia, and it's unstable anywhere in the country.

One more thing, it seems like the last firmware update, at least in the
US, was a little unstable, the current one seems to be stable. I found
this latest updates seems to be rock stable.
