One client can connect to VPN but not the other….



  • Here's a mystery. I have OpenVPN set up on my pfsense (road warrior). My phone and my laptop are both set up as clients (with different certs). Everything was working until today when I tried to connect with my laptop. It will connect to my LAN, but the internet is not reachable. On the phone, everything still works fine.

    What gives?



  • Maybe no DNS reachable? Try a lookup with IP address.



  • Tried it. No go. Also tried installing a different VPN client program (Tunnelblick and Viscosity). Same result.


  • LAYER 8 Netgate

    "It doesn't work" is not enough information to make a suggestion.



  • Tried with another Laptop?

    If another device reach LAN IP address, and reaches internet, is not crazy to think that the problem is not in the server.

    If its in the server, try with the same usr that cannot connect on your phone, and with the usr that can connect on your laptop, this is the unique variable that I saw on first plane, if the problem is on server.

    Interesting! Thanks for the suggestion. Here is what I came up with.

    1. Laptop user on phone: Works! By "works", I mean I can connect to my network AND tunnel web traffic through the VPN, i.e., "surf the web". Phone <–> LAN/VPN server <--> WAN

    2. Phone user on laptop on neighbor's network: Works!

    2. Phone user on laptop ON SCHOOL NETWORK: No go! Again, I can connect to my LAN/pfSense box/OpenVPN server, but I CANNOT get through to the WAN. Laptop <–> LAN/VPN server <--///--> WAN

    …So I am guessing it is something on my Macbook? I know we are venturing out of the scope of this forum, but what could it be?

    ..................

    Could it be the super-locked-down network I am on when away from home? It's a public university network that uses 802.1X. It seems everything is blocked except TCP 443 (which is what my VPN uses). Could it somehow let me connect to my VPN but not allow me to access websites? My setup USED to work on this network. Could they have somehow blacklisted my MAC? It seems to go against the point of the encrypted tunnel...
