Changing network interface type

[Grzegorz Wiktorowski]

The machine runs under VMware and has the network adapter defined as E1000. FreeBSD shows interface as em0.

I ponder to change the device to VMXNET3 (as recommended for VMware). Is it a simple task consisting of:
- shuting down the machine
- changing adapter type from E1000 to VMXNET3 in VMware control panel
- starting the machine

and additionally replacing ifconfig_em0= with ifconfig_vmx0= in /etc/rc.conf

or something more complex and sophisticated to perform?

if you have firewall rules it might be used there
various packages may use interface name

Right. I'm aware of this.

You can try to change interface name by adding the line like this to the /etc/rc.conf

ifconfig_fxp0_name="net0"      # Change interface name from fxp0 to net0.

But I have never checked it before.

Little known fact, you can use ifconfig_DEFAULT="....". Then it'll automatically pick the first ethernet adapter it finds, which works out great if there's only one. Things might get a little messy if there's more than one interface though.

Not sure if this would work but it's worth trying what im mentioned and combining that with ifconfig_DEFAULT:

ifconfig_DEFAULT_name="eth0"
