I've had a look at Eclipse's tech support pages. Looks like you have been allocated a /30 block of
addresses, 4 in total 2 usable (2 are the network and broadcast addresses). This is in addition to a
single address that is allocated to the ADSL router automatically when it connects to the service. 

A /30 block is ideal for m0n0wall and a cheap no-frills ADSL-ethernet router will do the job as long
as Network Address Translation can be disabled. NAT will be performed at your m0n0wall.

The two addresses you have are assigned to the Ethernet interface of the ADSL router and the WAN
interface of m0n0wall. m0n0wall uses the address assigned to the Ethernet interface of the ADSL
router as its default gateway. 

The instructions that Eclipse have for configuring a Speedtouch for no-NAT should give you a better
idea of what I mean, but use as a subnet mask. The subnet mask of
used in their example is for a /29 address block.

A suitable cheap router is the Conexant chipset based Dynamode R-ADSL-C4S @ £22.20 from Scan
(http://www.scan.co.uk/Products/ProductInfo.asp?WebProductID=96221). We use these all the time
together with m0n0wall on Soekris hardware. Just disable the routers internal firewall and NAT.
