Strictly speaking, you can't. Think of the gateway as "the next hop".
If you specify the 210.foo.bar.97 address as the gateway on the OBSD server,
it tries to send all outbound packets to itself and they never leave the
network. The gateway on the OBSD box would correctly be the 210.foo.bar.105
In my network setup, the gateway for all of the clients is the IP of the NIC
that is facing that client. So in your example, the gateway IP for the DMZ
machines would be 210.foo.bar.113 and for the local net 192.168.100.254.
