    Separate out WAN/LAN <> router ingress/egress on br0

    How would I go about separating LAN <> router ingress/egress and WAN (VPN/bypassed) <> router ingress/egress (all presently on br0)? I believe that one way is to create a veth pair - device veth0 and peer veth1, then add veth1 to br0, and then shift inbound WAN or tunX traffic to veth0 using ip...

    QoS Script for VPN

    Here is my QoS script to deal with a VPN and apply QoS with correct overhead depending on whether the VPN is active or not: admin@RT-AX86U-4168:/jffs/scripts# cat /jffs/configs/cake-qos.conf.add DLIF='br0' DLOPTIONS='wash dual-dsthost ingress' ULIF_TUN='tun11' TUN_PACKET_OVERHEAD='53'...

    Diversion Diversion and Wanduck

    Does Diversion with default options mess with Wanduck? I ask because i am experiencing a loss of internet connectivity associated with my modem dropping eth0 for about 3 seconds following a 48 hour LTE refresh and router not detecting change and hence not updating WAN IP. So it might be that I...

    Optimal LTE 4G MTU / WAN Packet Overhead

    Mindful of, e.g.: https://www.etsi.org/deliver/etsi_tr/126...80000p.pdf This makes me wonder: what is the optimal MTU set for a 4G LTE connection, to maximise throughput and avoid fragmentation? Should this value be the same in OpenVPN? I have been experimenting with QoS-CAKE, in which...

    Question about QoS

    Apologies for the stupid question, but when setting bandwidth to automatic or unlimited, what effect does the various QoS modes have, if any, on traffic? Take, for example, adaptive QoS. If its bandwidth is set to unlimited and it is set to prioritize zoom calls, what does it do, if anything...

    Backing up Router Config

    Just wondering - do most people regularly backup their JFFS / USB config? I created the following simple backup script to upload router config and tarballs of JFFS and the USB mount to OneDrive, which script could in theory be called every boot. But I am dubious that that is necessary? Script...

    DNSFilter vs VPN (+VPN Director?)

    What is the best way to ensure that DNS queries that arise via DNSFilter such as: Global Filter Mode: CleanBrowsing (Family) Get routed through the VPN thereby to safeguard against exposing DNS queries to ISP? The only way I managed to achieve this before was to specify: Force Internet...

    spdMerlin + CAKE [+ VPN]

    Fantastic add on Jack Yaz. AutoBW works perfectly with CAKE even with custom CAKE script override. For those using auto bandwidth calculations - do you still have the tests run every hour on 12 and 42 as default? I can see one issue with this is the tests may get distorted by other general use...

    Interaction between Cake-QOS and OpenVPN

    I spent some time trying to figure out why I could not control the buffer bloat on my connection using the default cake implementation in 386.2_6 until I identified that switching off my VPN (OpenVPN: NordVPN) removes the buffer bloat problem. What is the interaction between cake and OpenVPN...

    Double NAT? Confused!

    I have the following setup: ASUS RT-AX86U (192.168.1.1) -> Huawei 4G Modem (192.168.8.1) [Huawei 4G Modem connected to WAN port of ASUS Router] I have found that the only way I seem to be able to get my ASUS Router to pick up a WAN IP from my Huawei 4G Modem is to ensure that I set my Huawei 4G...

    Asus-Merlin JFFS wear?

    On the helpful wiki it is stated in https://github.com/RMerl/asuswrt-merlin.ng/wiki/JFFS: Given the above, why is JFFS enabled by default if its use results in wear and in particular why is syslog being copied to JFFS by default? Update: it looks from another thread like this may be something...

    Mysterious loss of connectivity

    I have the following setup: ASUS RT-AX86U (192.168.1.1) -> Huawei 4G modem (192.168.8.1) On the Asus router I have setup NordVPN via OpenVPN. After a few days (weeks?) of connectivity something eventually breaks and I lose internet connectivity until I reboot my router, which restores...

    Asus Router Antenna Tweaking

    My RT-AX98U RT-AX68U has three antennae and the manual states they should be left upwards. Have users experimented with tweaking the positions of the antenna to improve Wi-Fi performance? Would this make a mess of the beamforming?

    Why Asuswrt-Merlin is the Best!

    I would just like to share why having played around with the Asuswrt-Merlin firmware for some time now (386.2_6 on an RT-AX68U) I have come to really appreciate it. A huge thank you to RMerlin for his hard work on this project! I have a long history of having played around with linux...

    So I have the RT-AX68U and two TP-Link RE200 v4 extenders with OpenWrt installed. I would like to set up a WDS arrangement, as per: https://openwrt.org/docs/guide-user/network/wifi/atheroswds But it advises enabling WDS on the main router with: Is this something I can do under Asus Merlin...
