The idea behind this is anything (a device, another switch with lots of devices, etc) plugged into ports of your choosing will inherit the isolated VLAN membership you create. Scroll to the bottom and save, router will reboot again.Uncheck/remove any port(s) you want as members from VLAN 1.Don’t touch VLAN1 or VLAN 2 with the WAN bridge. Now you’re ready to create your new VLAN, this will be associated with the br1 bridge (or whatever you created above) for either a physical wired port on your router or a new virtual wireless network. NOTE: DO NOT use 10.0.0.1/24, for some reason (bug?) this range will not work even though it’s a valid RFC1918 address range.Īfter your router reboots you can check the bridge was created successfully, it will be in the MOTD when you SSH into the router and the ip a command should also show it. Scroll to the bottom and save, router will reboot.Enter an RFC1918 private address range (e.g.Navigate to Basic –> LAN and create a new bridge.For this I used br1 but you can use whatever you like. The first thing you’ll need to do is create a new bridge interface, this allows you to associate a new VLAN with a physical port (and later associate a virtual wireless SSID if needed). I’m still using the Tomato setup here however so check that guide out after you’ve got this how you like it. Update: : I am now using Pi-Hole and a Raspberry Pi2 to handle DNS for further privacy, filtering and to ward off advertisements and trackers. Everything done in UI, verification via SSH to the router.Existing flat 192.168.0.1/24 internal network using static DHCP.Existing 2.4GHz and 5.0GHz Wireless Networks.It most cases you can simply put the router in TFTP mode and shoot the shibby image over. I’m not going to cover setting up an ASUS RT-N66U or supported model with shibby firmware as that’s already covered in more detail elsewhere (in particular the comments are useful). Lastly, the Shibby Tomato derivative seemed to be the most active project with releases very often with new features ported in all the time. Also, DD-WRT started to languish in updates and releases with chipset support never being updated and their new focus on more commercial uses. I moved to Tomato/Shibby because it had the best support for my device. Long before I upgraded my home network to the ASUS RT-N66U I was a long-time user of DD-WRT and OpenWRT firmware to unlock the features and stability of my routers. Optionally whitelist and restrict all outbound traffic per VLAN/network.Provide a separate, virtual guest WiFi network or wired connection that allows internet access but no access to the rest of your network.Example: Put your Android Smart TV on an isolated network – you can still control it from your smartphone, laptop, etc by connecting to the isolated WIFI network but when the manufacturer stops releasing security patches two months after you bought it or that sweet NSA sleeper cell backdoor decides to activate it can’t become an attack vector into your private network.Access devices on the isolated network from your private network but not vice-versa.Put untrusted internet-connected devices and appliances on their own isolated network so they can’t sniff, attack, poke, prod or wreak havoc on your private, trusted network.Using isolated VLANs for wired and wireless clients via this guide will let you: Tomato will be using Linux bridges, iptables and vlans under the covers to provide your private network with a bit more security. I’ve accumulated a few devices over the years in my home which I do not trust completely – things like a Samsung Smart TV and I didn’t really trust anything that’s blackbox or not completely Open Source for obvious reasons. We’re going to cover setting up port-based and wireless VLAN support for traffic isolation on a network using the RT-N66U and Shibby build 1.32. They let you take full advantage of enterprise (and kitchen sink) features on the broadcom-based residential routers with support for OpenVPN, TOR, VLANs and a litany of other useful functions. I’ve been an ardent user of the Tomato Linux Open Source router firmware, specifically on the ASUS RT-N66U home routers using the ‘Shibby’ builds.
