If you can install an ethernet card in your DOS machine, you can 
have full internet access from it, through the Linux box.

The modem goes on your Linux box. Run ppp to connect to your

The ethernet port on your Linux box connects via a crossover
ethernet cable to the ethernet port on the DOS box.
Alternatively, you can use straight cables to connect them both
to an ethernet switch.

The Linux machine runs IP masquerading, or NAT, to extend the
IP connection to the ethernet. Let's assume you call the
Linux ethernet interface, and your DOS box

echo 1 > /proc/sys/net/ipv4/ip_forward
echo 1 > /proc/sys/net/ipv4/ip_dynaddr
iptables -t nat -A postrouting -o ppp0 -s -j MASQUERADE

And on your DOS box, you want to set up the Crynwr packet driver
appropriate for your ethernet card -- see
for packet drivers. 

DOS apps which use packet drivers are listed at
