How I get NIC real MAC address?

wallabybob

Your DHCP leases page shows a static entry for MAC address 00:25:86:9b:72:d3. The static entry means your DHCP server has been configured to always assign the same IP address (in this case 192.168.101.3) to the system with MAC address 00:25:86:9b:72:d3. The assign interfaces page shows your pfSense OPT1 interface has MAC address 00:25:86:9b:72:d3.

Why does a pfSense interface has a static DHCP entry in the pfSense server which hosts the interface? The static DHCP entry should be deleted!

I suspect the DHCP lease shows as online because its my recollection a DHCP lease shows as online if there is an entry in the ARP table. Because OPT1 is a local interface, if it has an IP address there is a permanent ARP entry for it hence it may appear online in the DHCP lease table.

You haven't made a convincing case you have duplicate MAC addresses on your network. And even if you had, you haven't made a convincing case that a duplicate MAC address is the cause of your PPP issue. How about posting a section of the PPP log showing the error report and a few line before and after it? And which interface is the PPP interface with the trouble (WAN? OPT1?)

well, the client web server's NIC is 192.168.101.3. and web server NIC MAC address is 00:25:86:9b:72:d3. this TP-link new NIC. about it is buy in 2010 year.

The PFsense server NIC MAC address is 00:25:86:9b:72:d3 also. this old computer's motherboard comes with the NIC card. about it is buy in 2005 year.

I don't know why it is has the same MAC address. I have not do change the TP-link new NIC MAC address. the old computer's is my family .

See if you can change the server MAC. Otherwise you will always have problems..

So I want to konw how get real MAC and fix it in Pfsense server.

I don't know how do it in freebsd system. :(

Stand By.

Your "Interface Assignment" page should look similar to this.

The old computer NIC how know my new buy NIC MAC address.

Even such a coincidence? ???

Almost unbelievable… Can you change NIC's in one or the other?

:P

used to modify ("spoof") the MAC address of this interface
