Routing IP traffic from client through server openvpn tunnel?

[Bob Willcox]

My FreeBSD gateway system has an openvpn tunnel connected to my Son's network
and when logged into the gateway system we can access his network throught the
tunnel just fine. But from other systems in my network it doesn't work. The
packets get over to the gateway system (maul) but no further.

This is the routing table on my gateway system:

Internet:
Destination        Gateway            Flags     Netif Expire
default            108.84.10.14       UGS        igb0
10.1.132.0/23      link#2             U           em0
10.1.132.1         link#2             UHS         lo0
10.4.0.1           link#4             UH         tun0
10.4.0.2           link#4             UHS         lo0
108.84.10.8/29     link#1             U          igb0
108.84.10.9        link#1             UHS         lo0
108.84.10.13       link#1             UHS         lo0
127.0.0.1          link#3             UH          lo0
192.168.2.0/24     10.4.0.1           UGS        tun0

Here's a traceroute from the gateway system:

bob at maul:2> traceroute 192.168.2.19
traceroute to 192.168.2.19 (192.168.2.19), 64 hops max, 40 byte packets
 1  coovas.knighthammer.com (10.4.0.1)  55.347 ms  53.420 ms  55.786 ms
 2  192.168.2.19 (192.168.2.19)  50.291 ms  48.516 ms  55.858 ms

And here is one from one of my other systems:

bob at han:1> traceroute 192.168.2.19
traceroute to 192.168.2.19 (192.168.2.19), 64 hops max, 40 byte packets
 1  maul (10.1.132.1)  0.261 ms  0.256 ms  0.244 ms
 2  * * *
 3  * * *

So my question is, what am I missing (likely on the gateway system) that would
prevent the packets from other systems being routed to the tunnel?

Thanks for any help,
Bob
