  • I have a XGS2300 HA-CLuster in active passive with 7 remote connections connected via SD-RAD 60. And one IPsec Site2Site-Tunnel connected to a cloud server. Any packet (ping is enough) from any network behind a RED to this cloud server or from the cloud server back will break the RED connection and force it to reconnect. Disbaled TLS1.2 for RED, re-created one og the RED interfaces, re-created the site2site Tunnel to tunnel-based, rebooted the firewall, set RED-Tunnel from Standard-split to standard-unified nothing works. Has anyone else experienced this?

  • What build version are you using?

  • Do you have GRO and NAT-t on?

    There is a known issue with 19.0.MR1 with that combination when ipsec acceleration is on (it is fixed in 19.0.MR2).

    If that is indeed the case, as a workaround, you can disable GRO (and have things work with ipsec acceleration on as well)
    Disable it on the parent netdev (oct0` on 1US/1UL/2Ua devices and `oct0, oct1` on 2Ub)
    ethtool -K oct0 gro off
    and then disable on the relevant physical port:

    ethtool -K PortXYZ gro off (replace PortXYZ with whatever port is applicable)
