Adding IP subnets to Soekris/m0n0wall router

I have a Soekris 4801 (http://soekris.com/, nice piece of hardware) and I am
using m0n0wall (http://m0n0.ch/wall/, v1.0). At this moment I am using it to
my personal ADSL line at everything works just fine but now I want to move
it to my corporate LAN.

At my office we have an ADSL line with 32 IP addresses and they a split into
3 subnets (2 x .248 and 1 x .240). The subnets are used as this below scheme
shows (I hope):

| INET/ADSL
|
| 8xIP (outside LAN)
[ SOEKRIS/M0N0WALL ]
| 16xIP (inside LAN)
| 8xIP (inside LAN)
|
| my LAN

Is it possible (how) to get this eviroment working on the m0n0wall?
