Realtek physical NIC config on host server



  • Perhaps this is obvious, but here goes. I'm running pfSense as a Hyper-V VM on a motherboard with 4 Realtek 8111C NICs. Not the best setup, but that's what it is. I know it's recommended to disable all the 'offloading' options in System/Advanced/Networking, but do these features also need to be disabled on the Host's physical NIC? For both IPv4 and IPv6 (I'm running both to the WAN)? Thanks for reading.

    IPv4 Checksum Offload - Rx & Tx Enabled
    Large Send Offload (IPv4) - Enabled
    Large Send Offload v2 (IPv4) - Enabled
    Large Send Offload v2 (IPv6) - Enabled
    TCP Checksum Offload (IPv4) - Rx & Tx Enabled
    TCP Checksum Offload (IPv6) - Rx & Tx Enabled
    UDP Checksum Offload (IPv4) - Rx & Tx Enabled
    UDP Checksum Offload (IPv6) - Rx & Tx Enabled
    


  • i never touched the settings in the host but i have them disabled in PFSense and i can pull 500mb+ dl with realteks



  • @Wizard76 Thanks for the reply. Since my post, I've tried both ways and really haven't really seen a difference, even in CPU (and my 10 year old Q6600 needs all the help it can get...). Thanks again.
