Enable gre support on OVZ?

SadySady Member

Hello,
Is "modprobe ip_gre" enough to enable gre support on whole OVZ host node or it needs something else to be done?
My host is saying that they has done this but neither "lsmod | grep gre" gives any output nor gre is working :(

    Thank you mate,
    They have did so on HN but lsmod | grep gre still doesn't give any kind of output on the VM, iptunnel command has been succeeded but gre still doesn't work. Do you have any idea?

    lsmod will never give you output inside CT even if the feature / module is enabled for your CT.

    My DDoS protected VPS gives that :(
    Any possibility which could be causing GRE tunnel to not work? I'm using buyvm's wiki guide & followed every step & there were no error so far but I can't ping internal IPs (192.168.168.1 & 192.168.168.2) from another server.

    Edit: Now I know why my DDoS protected VPS is giving output of lsmod | grep gre & that is because that VPS is KVM :)
