I think it should be the gateway as you are going to be proxying the dialup users onto
your local LAN.
The dialup box will proxy-arp the dialup users to the LAN and will forward their
packets to the gateway.

I have a similar setup to what you describe.
In my case the dialup is also the gateway which makes it simpler.

My config is:

server:
 set timeout 0
 set enddisc mac
 enable chap chap81 pap passwdauth
 enable proxy
 set ifaddr 192.168.3.2 192.168.3.80-192.168.3.100 255.255.255.255
 set server /var/run/ppp/ppp-server-%d "" 0177
 set dns 192.168.3.2
 set nbns 192.168.3.2
 accept dns
