I'm following the direction from here:  http://community.qnx.com/sf/wiki/do/viewPage/projects.networking/wiki/
Wifi_tcpip_config_wiki_page

But I can not get the "routing" to work.

I am bringing up a 3G data connection and the nameservers are being added to /etc/resolv.conf
I then follow the directions above to start my wireless adapter as a hostap and I am able to attach to the the AP that I
 created.  But my data packets are not routed between the wireless client and the 3G network.

I am able to ping off of the router via the 3G network so I'm pretty sure that everything to the "Internet" side is 
working just fine and I believe I have my dhcp.conf file setup correctly based on the examples.

Here is my pppd line:
pppd /dev/serusb1 defaultroute resconf require-ns noipdefault logstatus

Here is my "Network" portion of the dhcp.conf file:
subnet 192.168.253.0 netmask 255.255.255.0{
        range 192.168.253.100 192.168.253.110;
        option routers 192.168.253.1;
        option domain-name "my.net";
        option broadcast-address 192.168.253.255;
        option domain-name-servers 192.168.253.1;
        default-lease-time 600;
        max-lease-time 7200;
}

I have configured my wireless adapter with 192.168.253.1 as the IP address.

Thoughts?
