Setting up Guest Wifi On DD-WRT

I am a huge fan of DD-WRT but the problem I have is when i turned I turned DHCP forwarding on I lost the ability to have a "guest network".

I tried every tutorial online and none of them worked.

So after much trial and error I figured it out!

This video is a quick and easy way how to setup a guest network if your DHCP forwarding is on.

###### Firewall CODE #####
#Allow guest bridge access to Internet
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
#Block access between private and guest
iptables -I FORWARD -i br0 -o br1 -m state --state NEW -j DROP
iptables -I FORWARD -i br1 -d `nvram get lan_ipaddr`/`nvram get lan_netmask` -m state --state NEW -j DROP
#NAT to make Internet work
iptables -t nat -I POSTROUTING -o br0 -j SNAT --to `nvram get lan_ipaddr`
#Block torrent and p2p
#change the IP address to the IP of your guest network x.x.x.x/24
iptables -I FORWARD -p tcp -s 192.168.99.0/24 -m connlimit --connlimit-above 50 -j DROP
iptables -I FORWARD -p ! tcp -s 192.168.99.0/24 -m connlimit --connlimit-above 25 -j DROP
#Block guest access to router services
iptables -I INPUT -i br1 -p tcp --dport telnet -j REJECT --reject-with tcp-reset
iptables -I INPUT -i br1 -p tcp --dport ssh -j REJECT --reject-with tcp-reset
iptables -I INPUT -i br1 -p tcp --dport www -j REJECT --reject-with tcp-reset
iptables -I INPUT -i br1 -p tcp --dport https -j REJECT --reject-with tcp-reset
