    Hello

    Seems 3.8.1 upgrade has created some kind of problem with LAN-to-LAN VPN tunnel. If tunnel is up, it works fine. But if tunnel goes down because of disconnect or restart, then sometime tunnel hangs. Tunnel itself is up, but IP network and routings for that tunnel are down. I fix it usually by removing and readding IP-addresses for the tunnel.

    Tunnel itself is never down, only IP network inside tunnel is down.

    I have experienced this problem in several sites, several different installations.

    Hello,

    i have a similar problem with my VPN lan-to-lan bonding setup.

    Both VPNs are up / connected in the vpn tab.

    Under Network the Bond interface shows that VPN01 (second VPN in the bond) is down. VPN00 is always up, but the second one is always down since i updated.

    i now have gone back to 3.8, but having the newest version of ZS would be better.

    Could you try if the issues you reported are solved by the new bug fix #00 applied to Zeroshell 3.8.1?

    Thanks

    Hi fluvio,

    connection works for now but it is quite slow…but that could also be a problem at my site. Thanks for the fix tho.

    I will make a speedtest tomorrow and post the results.

    regards,

    Hi Fluvio,

    i made some test and it seems that the slow conection comes from a bug that i had before in zeroshell.

    The BOND only uses 10Mbit on each of my two lines in “Load Balancing and Failover” mode.
    If i switch to “Weighted Load Balancing and Failover” with same weight for both lines it uses both with 10Mbit for the download. But the Upload only goes over one of the two lines randomly but with the full bandwidth (32Mbit -4Mbit loss due to overhead as normal).

    hope you can help fixing it 🙂

    regards,
    Manuel

    Thanks for making these tests. Really the slow performance of VPN bonding is due to packet reordering.
    I hope to look at this issue soon.

    Hi fluvio, thanks for the rather fast patch of the VPN Problem.

    I did some test and now it works after just wainting some hours. It really depends on the PIng it seems.

    But it is still strange that it doesent uses the full bandwidth in upload.

    I use the “Load Balancing and Failover” mode, hope you can optimize the bonding because i really like it and use it every day.

    But 155Mbit/s thruput with encryption (AES-256-CBC) seems quite okay doesen’t it 🙂

    regards,
    Manuel
