Hi experts, I am unable to browse internet from guest wifi. I am using Linksys E3200 and Firmware Version DD-WRT v24-sp2 (03/25/13) mega - build 21061.

I followed this url to configure guest network,

I am able to get IP address from the router in 192.168.2.x subnet, after that no internet Sad. Also I am able to browse 192.168.1.1 UI from this subnet...here are my IP table rules...am I missing anything...

iptables -t nat -I POSTROUTING -o `get_wanface` -j SNAT --to `nvram get wan_ipaddr`
iptables -I FORWARD -i br1 -m state --state NEW -j ACCEPT
iptables -I FORWARD -p tcp --tcp-flags SYN,RST SYN -j TCPMSS --clamp-mss-to-pmtu
iptables -I FORWARD -i br1 -o br0 -m state --state NEW -j DROP
