![]() Side Question: On dd-wrt I allowed only incoming connection for ESTABLISHED connections. Option name 'VLAN Allow Internet for MAC' Can someone advice what am I doing wrong?Ĭonfig forwarding 'guest_turris_forward_wan' internet access is blocked for all destination addresses.īelow 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 Firewall Builder supports GUI based firewall policy configuration and management on the following firewalls: Linux iptables 2.4 & 2.It is used to set up, maintain, and inspect the tables of IP packet filter rules in the Linux kernel. What I need to do is restricting a VLAN which is bound to LAN4 on two different levels: Iptables is a powerful administration tool for IPv4 packet filtering and NAT. I am using a Turris MOX Classic which is running TurrisOS 4.0.5 ab9d1bf. If the fileserver is a linux host then just put iptables rules on the fileerver to reject the local hosts you dont want to have access.I have recently switched from dd-wrt to openWrt. #add this once to allow all other outgoing DD-WRT firmware replaces the existing firmware on a standard router - this process is often called flashing. Firmware typically affects how a device interacts with other devices. This kind of program is permanently integrated with a piece of hardware, such as a router. # this will block the service for every host on the network DD-WRT is a type of software called firmware. ![]() #for each outgoing service you want to block to all local host add one of these: # external service then you add one of these for each local client and external # if you only wanted to block the outgoing access for a given local IP to an Iptables -A INPUT -j REJECT -reject-with icmp-host-prohibited Understanding Network Topology Establish Network Connection Connect via LAN Cable Setup Wireless > Wireless Security Choose a Wifi WAN Band Goto. #for each local client that should not have fileserver access add one of these: Iptables -A INPUT -m state -state NEW -m udp -p udp -dport -j ACCEPT #for each incoming udp service you want to allow add one of these: Iptables -A INPUT -m state -state NEW -m tcp -p tcp -dport -j ACCEPT #for each incoming tcp service you want to allow add one of these: Iptables -A INPUT -m state -state ESTABLISHED,RELATED -j ACCEPT Core I7-10510U Firewall Mini PC mini computer industrial ClearOS DD-WRT m0n0wall.

Iptables -A INPUT -p icmp -icmp-type any -j ACCEPT I'm not familir with the wrt distro, so I am not sure where you should put these rules. If they do need to go via the router then I have included a rule that I think will help. in the same IP network and the same physical segment) as the packet will not need to traverse the router to travel between them. Stopping the local clients acessing the file server may not be possible if they are on the same nertwork (i.e. YouTube 0:00 / 9:37 Beginning Setup the DD-WRT Open Source Router Firmware as an Access. ![]() set up a WDS for my company a few months back and learned a lot, but it was using DD-WRT. Setup the DD-WRT Open Source Router Firmware as an Access Point / AP Only system behind a Router. I can't give you an exact answer, but the following should help and give you a rough idea. So I am attempting to learn more about firewalls, NAT, vlans.
