I am using dnsmasq to try and share my internet connection.

Network is as follows.

Internet --> Router -wlan0-> Debian Box (sprocket) -eth0-> net enabled blu-ray player (Sony S370)


Sprocket can connect to the internet via router over wireless and the S370 can connect to sprocket using dhcp from dnsmasq. However it is unable to connect to the internet. I have enabled ip forwarding, set some iptable rules and setup the blu-ray player to use sprocket as the dns server. I can ping the blu-ray player from sprocket so the connection is up however still no internet.

Any help would be greatly received.

Thanks

Harry

how's your iptables rules? and your dnsmasq config?

iptables rules:

iptables -A FORWARD -i wlan0 -o eth0 -s 192.168.0.0/24 -m conntrack --ctstate NEW -j ACCEPT
iptables -A FORWARD -m conntrack --ctstate ESTABLISHED,RELATED -j ACCEPT
iptables -A POSTROUTING -t nat -j MASQUERADE

dnsmasq.conf:

only changes made to default config are specifying eth0 as interface and assign dhcp ranges.

Is this likely to be a dns problem?

Post your dnsmasq.conf file, comments stripped please.
oh, and I think its better to use -I instead of -A in your iptables rules. At least, while you're doing tests. later, you can integrate them in your firewall

dnsmasq.conf
