That way itвЂ™s a simple (but annoying) power cycle to get things back up. Do it all from the command line with a known-good startup. Note to keep you sane: donвЂ™t do any of this testing in the startup scripts or youвЂ™ll brick your router, guaranteed. This was an incredibly frustrating learning curve as everything I could find made it sound like this was the way to configure a firewall in Linux, but it just wasnвЂ™t working. This is not the case: bridged packets donвЂ™t reach iptables at all! The best I could do was block everything (manual restart needed), or otherwise blow up the configuration (manual restart needed) as I tried to mess with the bridge. WeвЂ™re halfway there.Д«eing unfamiliar with iptables (we use OpenBSD and pf for firewalls around here), I was under the impression that iptables rules would work in a bridging environment. Apply these settings, and youвЂ™ll basically have an expensive dumb switch вЂ“ all traffic shows up on every port, and thereвЂ™s no logic at all. Lastly, under Advanced Routing set the Operating Mode to вЂњRouterвЂќ so it stops trying to do NAT. This will give you a checkbox to bridge the LAN and WAN: вЂњAssign WAN port to switchвЂќ. Once you have the LAN configured, you need to set the WAN connection type to вЂњdisabledвЂќ. YouвЂ™ll also need to enable SSH access and remote configuration вЂ“ but be sure to lock this down once the firewall is running! First, set the LAN to use a static IP and make sure you can connect via another machine to configure it. Next I needed to bridge the WAN port with the LAN ports, which ended up being a struggle until I found the easy options in the dd-wrt GUI. This actually requires a startup script on the router, with a line to remove the wireless module so it wonвЂ™t try to reenable itself: wl radio off The last thing I want for the firewall is to be broadcasting an SSID and allow wireless associations. The first step after flashing the firmware with the latest dd-wrt build (v24-sp2) was to take off the antennas and turn off the radio. (We bought local so weвЂ™d have it sooner, and it was a bit more). We went with the WRT54GL, currently as cheap as $50 on Amazon. Linksys wireless routerД«eing familiar with the dd-wrt project, I was pretty sure I could build a firewall out of a Linksys router. Not having a spare on hand, I was scrambling for a solution. Until last week these were protected by an aging OpenBSD firewall running packet filter and all was well until midweek when the motherboard failed. Side Question: On dd-wrt I allowed only incoming connection for ESTABLISHED connections.New Media has a number of development servers located in-house where we get stuff done before releasing it out into the wild. Option name 'VLAN Allow Internet for MAC' Can someone advice what am I doing wrong?Д¬onfig forwarding 'guest_turris_forward_wan' internet access is blocked for all destination addresses.Д«elow I have attached my firewall rules. Iptables -I FORWARD -i vlan2 -o vlan3 -p tcp -s XX.XX.XX.XX -m state -state ESTABLISHED -j logaccept The rules I used on dd-wrt where as following (VLAN2 = WAN interface, VLAN3 my own VLAN) iptables -I FORWARD -i vlan3 -o vlan2 -p tcp -d XX.XX.XX.XX -dport 443 -m state -state NEW,ESTABLISHED -j logaccept I had this perfectly working with dd-wrt and tried to apply the same idea on open-wrt firewall builder. Allow only one special IP and port combination for other all other devices and block the rest of the internet.

Allow Internet Access for one special MAC.

What I need to do is restricting a VLAN which is bound to LAN4 on two different levels: I am using a Turris MOX Classic which is running TurrisOS 4.0.5 ab9d1bf. I have recently switched from dd-wrt to openWrt.
