Jonathan,

Although I really struggled to read your post, this is what I think you 
want to do.

LAN contains 5 ish computers on 203.7.226.0/24.

Dialup Internet is connected to the LAN. These computers access internet 
via dialup.

ADSL Internet <- FreeBSD Machine -> LAN

There will be no connection to the Internet via the ADSL from the LAN. 
Only the one FreeBSD machine can access the ADSL.

In this case, there is no bridge. Bridges are for connecting physical 
connections (cables) together on the same IP network subnet using two 
network cards.

You simply have two network interfaces on the FreeBSD machine. One is 
the LAN network, one is the ADSL address.

Of course, it is easy to route data from the LAN over to the ADSL using 
this FreeBSD machine and a NAT. Why you would choose to use dialup for 
Internet surfing over ADSL is beyond me.
