comment IP masquerading, rule to forward packets between the Interfaces (on a multihomed network device)
@Marius, Due to some setup issues, I haven't tried the solution. I am just curious to know on what is wrong in the proposed method, i.e reading the DNS server IP from the resolv.conf file corresponding to the eth0 and using the same for wlan0. The clarifications I needed in the method you suggested are: 1. Won't the DNS queries become slower ? 2. Let's say if we want to productize this solution, what is the guarantee that the DNS server IP's won't change. So, wouldn't it be better if we always get the DNS server IP's dynamically via the DHCP server to which eth0 is connected.

Okay, thanks I got some handle on this issue. Probably I can try to use the output of cat /etc/resolv.conf |grep -i nameserver|head -n1|cut -d ' ' -f2 to the dhcpd.conf

Sorry to bother you. But the question is which DNS server IP should I use? Won't the usage of Google's public DNS servers slow up the queries ?

I am running a DHCP server on the AP. I am not clear on the IP that I should use for 'option domain-name-servers' so as to forward the DNS queries to the NAT that is connected to eth0

Your suggestion is valuable. I am able to ping to 8.8.8.8. Does that mean DNS settings are missing for my wifi clients?: How do I get that
