Dpinger used to monitor vpn gateway connections - blocked



  • I have two VPN connections with ExpressVPN.
    If the monitor address is set to google, they should with 50% packet loss

    from my linux pc, if I use linux traceroute, I get the following results

    • I believe this is a UDP traceroute
      traceroute to google.com (172.217.23.174), 30 hops max, 60 byte packets
      1  10.x.x.x (10.x.x.x)  35.904 ms  35.882 ms  35.873 ms
      hosted-by-i3d.net (31.204.154.1)  35.864 ms  35.853 ms  35.843 ms
      100ge.cr0-br3.smartdc.rtm.i3d.net (109.200.218.166)  35.830 ms 100ge.cr1-br3.smartdc.rtm.i3d.net (109.200.218.246)

    • I believe this is an ICMP traceroute
      traceroute -I to google.com (172.217.23.174), 30 hops max, 60 byte packets
      1  10.x.x.x (10.x.x.x)  26.314 ms  26.318 ms  26.316 ms
      2  * * *
      3  * * *

    If i understand this correctly, it seems that hosted-by-i3d.net (31.204.154.1) does not pass ICMP

    Are there any other options/way i can monitor the vpn connection to enable failover of the vpn connection.



  • Here are some other anycast dns servers you can try for monitors… see if any of them are more reachable/reliable than 8.8.8.8....

    Oracle-Dyn
    216.146.35.35
    216.146.36.36

    HurricaneElectric
    74.82.42.42

    Level3
    4.2.2.1
    4.2.2.2
    4.2.2.3
    4.2.2.4
    4.2.2.5
    4.2.2.6



  • Just a note to luckman212… Verizon and Level 3 have no affiliation with each other. Those IP addresses you posted belong to Level 3.

    Level 3 was recently acquired by CenturyLink, in an effort to increase business/enterprise services. Verizon has nothing to do with them.



  • Thanks for the info
    I corrected my post…
