Hi Larry,

Well, I had a similar problem dealing with wifidog + freifunk olsr. I  
had a mesh network where some of the nodes running wifidog/olsr would  
contact the wifidog server through the wifi interface, that is the  
same where the clients are connecting. So, you have the iptables  
firewall rules from wifidog denying  packets from clients and on this  
setup other nodes are considered clients, so, you can't contact the  
server. The solution that I come up to was to whitelist the mac  
address of the nodes on each of the wifidog.conf setup  
(TrustedMACList) and a small cron script to alter one of the iptables  
rules to allow client authentication. Something like this:

iptables -t filter -R WiFiDog_WIFI2Internet 3 -i eth1 -s !  
-m state --state NEW,INVALID -j DROP

I had the NAT/OLSR configuration on Freifunk. All the clients  
connecting through each node are NAT'ed to the mesh with the ip  
address of the node (eth1/mesh side). It worked for me, don't know if  
it works with you.
