Hey all, I am completely new and need help becouse i would like to realise an isolated network. I hope i give you enough information:
1: What router-model is it?
ASUS RT-N66U
2: What firmware version is used?
I decided for: dd-wrt.v24-26138_NEWD-2_K3.x-big-RT-N66U and it works good. I found a newer one (dd-wrt.v24-27506_NEWD-2_K3.x-big-RT-N66U); should i update?
3: : How did i flash the router? -> 30/30/30 sec. wrt.com/wiki/index.php/Multiple_WLANs Reset ?
I would like to share one internet connection with my neighbour.
5:how is the Router connected to the Internet?
Der Router is connected with Repeater Mode with the WIFI from the cablemodem.
5: What do i want to create / Whats the problem?
The N66U should make a 2.4Ghz + 5ghz Wifi Network which is isolated from original network (192.168.1.X). 2,4 + 5 ghz are necessary becouse not all my devices can use 5 ghz.
In the following pictures you can see the settings i made . I was reading this guide http://www.dd-wrt.com/wiki/index.php/Multiple_WLANs .
Router got IP 192.168.2.1
The settings for the two Wifi networks were done and on br0 it works but is not isolated.
Now i created br1 for isolating (192.168.3.1) and assigned wl0.1 und eth2 to it. Multiple DHCP on br1 got activated. But then the Problem is: no internet access on wl0.1 and eth2.
I think there are missing some Iptables or Firewall settings? Or is my request not possible?
I was reading a few guides about „GUEST-Network“ to find the right settings…
For testing i only assigned wl0.1 on br1 and now i get no connection:
ADDED:
Firewall
iptables -t nat -I POSTROUTING -o `get_wanface` -j SNAT --to `nvram get wan_ipaddr`
iptables -I FORWARD -i br1 -d br0 -m state --state NEW -j DROP
iptables -I FORWARD -i br0 -o br1 -m state --state NEW -j DROP Are this both commands necessary? or influence LAN Port connectivity?
iptables -I FORWARD -i br1 -d `nvram get wan_ipaddr`/`nvram get wan_netmask` -m state --state NEW -j DROP
iptables -I INPUT -i br1 -p udp --dport 67 -j ACCEPT
iptables -I INPUT -i br1 -p udp --dport 53 -j ACCEPT
iptables -I INPUT -i br1 -p tcp --dport 53 -j ACCEPT
iptables -I FORWARD -i br2 -d `nvram get wan_ipaddr`/`nvram get wan_netmask` -m state --state NEW -j DROP
iptables -I INPUT -i br2 -p udp --dport 67 -j ACCEPT
iptables -I INPUT -i br2 -p udp --dport 53 -j ACCEPT
iptables -I INPUT -i br2 -p tcp --dport 53 -j ACCEPT
WLAN network works now!
But I think there are maybe some small mistakes in the configuration. Can someone PRO check it?
But there is still the Problem with the LAN Ports. With cable it is not possible to get a an ip or a connection. WHY
Please Help
I would be grateful for help because it took me lots hours to come until HERE. THX
I think Repeater Mode without bridge is the right way because all (LAN, WIFI 2,4 and WIFI 5 GHZ) should be independent from WAN Network.

do you need to bridge your vlan with eth2 and wl0.1?
maybe. Becouse my Printer is in 2,4ghz wl0.1 and computer 5ghz eth2. But the problem is: if wl0.1 and eth2 are on the same bridge (br1 or br2) there are connection problems
I tried to add vlan0 to br1 and also to br2 but Ethernet-Ports are still not working and there are still connection Problems :

Now tried to clear NVRAM with Putty. But next Problem is after typing the Login-Name I am not able to enter the password and I can´t send the NVRAM Clear code. I tried to ignore what I see and type the password but regardless it say´s: Login incorrect . WHY?
Now after firmware restoration no dd-wrt network is coming up . Now I try to flash original ASUS Firmware. It worked and I am on original firmware now but I am not able to get back to DD-WRT
Flashing to original Firmware always works but after that flashing to DD-WRT mini or big doesn´t work
I am a few seconds before to throw it out the window because with DD-WRT it is not booting/coming up...
Is it possible to work with putty commands and ASUS-Firmware? ok I found the answer: no
but when I am connected in my WORKGROUP "Homenetwork" I can´t see it WHY?[/u]
This worked:

Hi Bill
I have also done some DD-WRT (will start posting them at a later date so make sure you keep coming back as I’ll be including DLNA and torrenting too).
When I was doing mine I found that it doesn’t always register it for some reason so try the following:
1) Open file explorer
2) Enter the IP of your router in the address bar like so \\192.168.1.1 (or whatever your default IP is)
3) it should now appear with the different partitions you have (I have mine on two parties and you will find out why in a later article)
4) right click the partition and select mount as drive.
