    OpenVPN Tunnel MTU

    Actually ping on asuswrt-merlin 386.3_2 has very different syntax. I got the same numbers as you. Jan 11 18:19:46 ovpn-client1[17699]: NOTE: Beginning empirical MTU test -- results should be available in 3 to 4 minutes. Jan 11 18:22:50 ovpn-client1[17699]: NOTE: Empirical MTU test completed...

    OpenVPN Tunnel MTU

    Spectrum said to use MTU 1479, which I could easily set on the WAN side. I can certainly test that number for the tunnel, but we will still have the same open question, which is how do we set the OpenVPN server side tunnel MTU on an Asus router running asuswrt-merlin 386.3_2? So far we only...

    OpenVPN Tunnel MTU

    It is as you expected. Local log complains of a mismatch between local and remote tunnel mtu settings. So back to my question of how we set the OpenVPN Server tunnel MTU on a router running asuswrt-merlin 386.3_2? Jan 11 17:58:39 ovpn-client1[15617]: WARNING: 'link-mtu' is used...

    OpenVPN Tunnel MTU

    Thanks. Same result. Whether I put it in the ovpn file and upload the file via the UI, which ends up in the Custom Configuration textbox, or I manually edit the Custom Configuration textbox, neither seem to act on "tun-mtu 1200". Only applying 1200 via the "ip" command at the SSH command line...

    OpenVPN Tunnel MTU

    Thanks for all your help. Putting "tun-mtu 1200" in the .opvn file and uploading it to the asuswrt-merlin router has no effect. The custom settings section of the UI acknowledges the additional lines, but the tunnel mtu is unchanged. As I mentioned in the original post, "/usr/sbin/ip link...

    OpenVPN Tunnel MTU

    Thanks. mssfix in the local config file improved the situation. Unfortunately tun-mtu and fragment both have to be set on both sides of the tunnel. The other end of the tunnel is an OpenVPN server on a similar Asus AC1900 (RT-AC68U) router running asuswrt-merlin 386.3_2. Any ideas how to set...

    OpenVPN Tunnel MTU

    Hi All. I have an Asus AC1900 (RT-AC68U) router running asuswrt-merlin 386.3_2 sitting behind a separate Spectrum wireless router and a separate Spectrum cable modem. The AC1900 connects and routes all traffic to an OpenVPN tunnel. Per Spectrum, who recently updated my modem and router, I had...
