Speed and Duplex Interface Options Missing

[maccipher256]

Need to configure the Speed and Duplex settings for existing LAN and WAN interfaces, however the do not display on the Interface Settings page for each.

If I create a new interface, these settings are available.  Seems to be a bug?

My only option is to delete the existing interfaces and create new, however I lose all previous firewall rules and other settings.

Any advice please?

Note, I'm doing this as my X550-T2 card doesnt advertise/negotiation 2.5G with my Openreach 2.5G PON.

It should be there (I believe), so long as those interfaces use the physical NIC devices directly - e.g. if your WAN is PPPoE, you can't set speed/duplex on your "WAN" interface - you'd have to assign the underlying physical NIC to another interface (with no IP address), and configure link settings there.

Hi, thanks for responding.  The underlying is a PPOE, however the PPOE definition doesn't have these settings either.
