NAT configuration questions...

I have a DSL modem connected to a broadband router.

The dsl modem is a SIEMANS speedstream 4200
The broarband router is an SMC BARRICADE SMC7004AWBR.

The DSL modem is allocating IP addresses in the network, 10.0.0.XXX
The SMC is allocating IP adresses in the network 192.168.2.XXX

I Can't reach the SMCs web server.... Why? I don't know.

I want to be able to use Limewire and/or Azureus, but neither is
working.. probably nat stuff...

What do I do?
