HELP: Can ping my cousin's comp over the internet via LTE but not via PLDT

  • A) My Wan IP = 112.206.24.27 (dynamic with DDNS) - PLDT Fibr Plan 3799 - 200Mbps
    B) My Cousin's WAN IP = 112.206.24.87 (dynamic with DDNS) - PLDT Fibr Plan 3799 200Mbps

    1) I tried to use my iphone Globe LTE to ping my cousins WAN IP = success
    2) I tried to use my iphone via my PLDT wifi to ping my cousins WAN IP = fail
    3) I tried to use my desktop via my PLDT to ping my cousins WAN IP = fail
    4) I tried to use my asus AC86u router via PLDT to ping my cousins WAN IP = fail
    5) My friend using PLDT can both ping my WAN IP and my cousins WAN IP = success
    6) My friend using Globe internet cannot ping my WAN IP but can ping my cousins WAN IP = fail/success
    7) Tracert to my cousin's WAN IP shows 2 hops = "destination host unreachable"
    8) My cousins comp using his PLDT can ping 8.8.8.8 and 9.9.9.9 without any problem
    9) My comp using my PLDT can ping 8.8.8.8 and 9.9.9.9 without any problem

    What could be the problem? I need to be able to ping my cousin's WAN so i can use VPN, etc.

  • bridge mode? if yes, check router for potentially blocking connections from certain IP (some router have this stupid DDOS protection/anti-hacking, just disable those junk). if not bridge mode, then check other settings that can potentially do this.

    if this still doesnt work, it maybe better use a P2P tunneling service like zerotier, no hassle it just works.
  • Yes im in bridge mode and i turned off all my firewall antihacking in both routers and antivirus in pc but still the same. I want to really solve this problem without using p2p. Im also interested to know the solution.

  • Anyone else?
  • baka naka terminate kayo ng pinsan mo sa iisang switch ng PLDT and baka naka Private VLAN implementation sila.
  • @banono27 - if ever we are, hindi ba dapat i can still ping him kasi ang naka display naman is his public ip? I tried 3x online ping sites and they can ping both our public IPs successfully.

    update: nag iba na IP since we restarted modem

    Mine - 112.206.24.98
    Cousin - 112.206.24.87

    Both can be pinged by the three online ping sites pero i cant ping the .87 from my house

  • @joms

    try moving somewhere else, eg lumayo kayo, kung nasa QC ka, punta ka sa meycauayan and connect to mobile network, do the test, if it works, then its probably a routing table misconfiguration sa side ng Smart. nothing you can do about it if that's where the case. hindi mo rin naman pwede itawag yan sa support since thats out of their scope.
  • @polka - hindi ko kelangan lumayo kasi from my house, if i switch my phone from wifi to LTE, i can ping my cousin's IP address
  • @TS
    try to restart one modem and get an ip that is on a different subnet.
  • I can ping your cousin's IP. So no issue sa side ng cousin mo (I'm using Globe fiber plan).
    Yung sa iyo ang di ko ma ping.

    Possible issues: Firewall ng router mo, ICMP issue ng router,
    Naka bridge mode na, right? So just check your 3rd party router configurations, since yung 3rd party router ang usually nag rereply sa ping.

    EDIT:
    Teka, I can now both ping your IP addresses. Mukang di sya static, baka iba na IP nyo both ?? LOL. And I am pinging someone else IP address ?? LOL

  • yes hindi sya static. i also tried to bypass my asus 86u router and connect the modem directly to my PC. Hindi ko pa din ma ping yung cousin ko when doing this but i can ping 8.8.8.8 and 9.9.9.9 and google.com, etc.

    Anothe thing i tried, i connected to my Expressvpn account and used Philippines and USA and hongkong. When doing this, i can ping my cousins IP address pero once i turned off the expressvpn, ayaw na.

    WAN IP ko ngayon is 112.206.24.27
    My cousins IP is 112.206.24.87
