I've been searching far and low to try and get this configuration working.
All I want to do is configure my asus rt-n66u router running ddwrt to isolate port4 from my private network, yet have internet access on it.
Doing this on a wrt54gl running dd-wrt was easy but my rt-n66u doesn't seem to like this setup as much. I can get as far as having the device on port 4 get an ip address from the secondary dhcp server, but no internet access. strangely enough i also seem to be able to ping the 'private' devices but not 220.127.116.11.
Any advice would be truly appreciated!
Info: My router IP Address is 192.168.1.1, DHCP Server is ON. PPPoE connection to the internet.
EDIT: I am unable to add additional screenshots.
dhcpd is ON for vlan3, range: 192.168.2.100-150
firewall config is as follows:
iptables -I FORWARD -i vlan+ -o vlan+ -j DROP
iptables -I FORWARD -i vlan+ -o vlan2 -j ACCEPT
iptables -I FORWARD -i vlan2 -o vlan+ -j ACCEPT
