    How to enable port randomization in Asuswrt-Merlin?

    By default pfSense will port randomize all outgoing UDP connections (reference), which some say indirectly improves the privacy and security of devices behind the firewall. This basically turns NAT into a more restrictive level. for example, a device behind the LAN wants UDP port 48695 open...

    Can I repurpose an outdated gaming machine to be a home networking firewall with Linux and pfSense

    So I wanted to turn an old computer into firewall hardware. Could I use the input connection on the motherboard to utilize the hardware on the computer and output on a PCIE NIC to my router while running pfSense on Linux? or would it be better to sell my computer and get an open platform device...

    Is it normal for the firewall to restart by itself? notify_rc restart_firewall

    Hello! I was looking through the logs of my RT-AX58U router and saw that the message "notify_rc restart_firewall" comes up sometimes. Usually after an attempted update, or sometimes after a reboot. Had about 14 instances of this happening over a couple of months. Is this normal/safe?

    How to restrict VPN network access to certain IP Range or Hosts for specific VPN client

    I like to add for the VPN access some policies or firewall rules which should only allow to access a single machine in the network for a given VPN Client / User. How Can I do that? Lets assume I have a server in my network "192.168.1.100" and a VPN user "server admin". The VPN Client IP Range...

    Firewall rule to allow only a specific domain name

    Behind my AX86U I am monitoring a device via SNMP. The SNMP manager initiates the communication by using a non-standard port. So I created a forwarding rule that redirects the non-standard port to the internal device. Something like this: external [diff UDP port] -> internal [snmp UDP 161]...

    Why does my RT-AX88u show ports 80,443 & 21 open from WAN?

    I am sure this kind of question gets asked a lot but I have been reading many different forums/threads/sites and I just cant figure out why Nmap is showing ports 80, 443 & 21 open on my router. I have UPnP & Port Trigger disabled & I only have 1 port forwarded which is for my Plex server. So why...

    How exactly do IoT smart devices pose a threat to home networks?

    I'm just curious, how exactly does a smart lock, or a light bulb or a smart kitchen appliance pose a threat? If you have your router properly set-up, disabled UPnP, enabled the firewall and no port forwarding, then there's no way some remote hacker can enter my home network through a security...

    Allowing just one device to subnet (iptables or Network Services Filter?)

    Due to my ISP forcing me to use their router if I want to use their bundled VOIP service, since upgrading to FTTP I now have to have my ASUS sitting behind my ISP's router. Annoyingly they don't allow their router to run in a bridged mode. As much as I can I have tried to make it a native...

    RT-AX86U, turning on firewall breaks IPv6

    Hey, The fix for this is probably simple but I can't figure it out. I've hooked up the Asus router to my ISP modem with DMZ enabled towards the router. When I turn off the IPv6 firewall in the Asus settings, IPv6 works fine. When it's turned on it stops working. I tried opening port 546 UDP...

    IPv6 Firewall rule for whole network possible (port opening) instead of local IP?

    Hi there, just registered as I’m thinking of buying a new router (GT-AX11000 Pro or GT-AXE16000) and I’m not sure how well IPv6 firewall rules are configurable. I need some open ports for my dual stack WAN. As I got it right port forwarding for IPv4 is possible, but is it possible to just create...
