Does this mean that you do PPP via the modem? If so, you should have
some interface tunN with the IP assigned by the ISP.

you must enable gateway in the rc.conf file with:

if you connect the two other boxes directly to the NICs of FreeBSD you
must use crossover cables and should assign to each connection a
separate network; or you connect all three boxes via a HUB or switch in
only one network;
the other boxes should have the FreeBSD as default gateway in their
routing and in the FreeBSD you must use IPF and IPNAT to hide your
network(s) behind the tunN interface's IP addr; I do this at home too
having attached by Linux based cellphone via USB networking and this
has access to Internet through the FreeBSD laptop;
