Yes it will, just don't enter a ip-address for the local and remote
end of your modem connection. See an below

#!/bin/sh
/usr/sbin/pppd connect '/usr/sbin/chat -v -f <chat_script>' /dev/ttyC0 115200 crtscts asyncmap 0 modem name <name> defaultroute :

As you can see there are no ip-addresses left and right of the ':'
character which means that they will be dynamically allocated, this is the 
ip-address of the remote end of the link and the local ppp interface.

Configure the 'gateway' option on all other workstations and servers
to point to the ethernet address of your NetBSD box. Make sure that
ip forwarding is enabled on this machine and it would be wise to setup
a firewall using a combination of ipf and nat. 

dingo# sysctl net.inet.ip.forwarding
net.inet.ip.forwarding = 1

You can set it by issuing the following command as root user:

sysctl -w net.inet.ip.forwarding=1

Have a look at

I found them very helpful
