Ping problem on Ipsec

  • Hi all,

    Sorry beforehand for my very bad English :D…

    I discovered yesterday ipsec so sorry if I'm not always the exact terms.

    So here is my problem. I configured a ipsec server on pfsense without problem.

    I runs the client and ipsec connection that goes well.

    Here the network diagram :

    VPN client: ---------- ---------- Internet WAN (PPPoE): - pfsense - LAN: - ------- Lan:

    The problem is that when I'm connected to VPN I can not ping remote computers in

    I started a ping from to I ran Wireshark on the post and ping arrive well. But the return it passes less well.
    The traceroute of on indicates me that after, packages it lose.

    Have you any idea?


  • while I'm REALLY new to pfsense (like 4 days old haha), I had a problem similar over my ipsec vpn. I could ping from the remote office to the main office, but not the other way around.

    I ended up going to Firewall -> Rules -> IPsec @ the remote office, and made an "any" rule (any protocol, source, port, destination, gateway). Once I did that, I could ping and traceroute both ways across the link.

    Basically, you have to treat the IPsec tunnel as any other network adapter it seems. Hope this helps.
