Sophos Firewall on Bare Metal PC Hardware: Surgery to Change NIC

BDK

Running Sophos Firewall v18.5.1 on bare metal PC hardware. Preparing to swap 4-port NICs: out with the Intel I350-T4, in with the Intel X710-T4L. My _hope_ is this works as follows:

  • Proper shutdown
  • Remove I350-T4
  • Install X710-T4L
  • Power on
  • New hardware is recognized, new driver used, Sophos Firewall is copacetic
  • A bit of work in Network > Interfaces to stich everything back in place

QUESTION: does Sophos Firewall tackle new hardware (change of NIC) as I imagine above?

Confirmation would be awesome, though I would be sincrelygrateful to know potential gotchas BEFORE performing surgery.

Cheers,
Bruce

    Ian--

    Xfinity is very good to me: every other year they 'bump' my Internet speed at the same price, to keep ahead of the fiber-to-the-home guys, and I'm currently getting 1500Mbps down.

    My file server is already humming at 2.5Gbps and much of its traffic routes through Sophos Firewall to the (new) WiFi6E access points.

    10Gbps is total overkill, as you correctly observe, now and into the forseeable future. I was unable to identify a four-port 2.5Gbps NIC that is conclusively supported by Sophos Firewall, despite the presence of 2.5Gbps ports on Sophos hardware. So rather than serve as an independent hardware compatibility testing lab, I landed on the X710-T4L.

    Cheers,
    Bruce.

    Hi,

    assuming your new device is a 4  port NIC, then make sure you have a current backup, then make you changes then perform a restore, the only real issue will be your NICs (interface) order might be different from your original.

    Appreicate the crazy-fast reply AND the positive news! Both the old and new NICs are four port, though I am kinda expecting that the port-to-zone assignments may need to be re-jiggered in Network > Interfaces.

    I'll have a monitor and keyboard attached, just in case I need to access the console.
