Remote LAN over GRE unavailable

  • I have SITE1 & SITE2 setup with a GRE connection between them. I am using OSPFd for routing to be able to reach remote subnets from each side.

    For the most part, connectivity is without issue. From SITE1 I am currently unable to ping hosts on the SITE2 LAN - I can ping them just fine from the SITE2 box but from the SITE1 box or LAN hosts they time out.

    I see them get through the firewall on SITE2, just no reply.

    Config between the boxes are nearly identical. I have completely open firewalls on the LAN and the GRE tunnel interface for testing this.
