Changing WAN MAC Address (Solved)
-
What is the best way to change the WAN's Mac address? I tried both at the CLI and via webconfig's WAN interface tab unsuccessfully and I end up with WAN having both a hardware Mac address and an ether Mac address. When this happens, dpinger gets stuck in error 65 - no route to host, then the pfSense box takes, what seems forever, to complete the boot up process. That results in WAN having or getting no public IP and often ends up with 0.0.0.0 or n/a. I would like to change because I keep getting pfB_PRI1_v4 members trying to make TCP or UDP request to connect to my old PBX server address a year ago that doesn't exist...yes, I know they're not going anywhere...they seems to take over my firewall logs with entries.
igb0: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> metric 0 mtu 1500

That's what it;s supposed to look like when you spoof the MAC. And via the WAN config in the GUI is where you should do it.
You are doing this just so you get a different public WAN IP?

Yes, Yes, Yes...how to? Had been wondering whether my ISP locked that address to my modem since it's my own. I had placed an Apple Extreme in front just to see whether I would get a different address, and I did.

You sure its a modem and not a gateway? Do you get an actual public IP on pfsense wan?

Yes, pfSense gets a public IP but it seems it was the same address before the ISP and me war a year ago.

@nollipfsense well if you are on a dhcp normal sort of leasing, changing the mac of the device connected to your cable modem should change your IP.
Most of time with a cable modem, and you change the device (or mac of this device) you need to power cycle the modem and then connect the new device or device that you changed the mac on.
What I would do is disconnect pfsense from your modem. Power cycle the modem - then once its lights show that is connected to your isp. Reconnect pfsense after you have changed it mac - and if via normal dhcp leasing this new mac would/should get a new IP from the dhcp server of your isp.

Makes sense and was the only step I did not do...I keep the Ethernet cable connected and was just power cycling the modem on/off...that's why dpinger got stuck...the cable was still connected, look at that!

@nollipfsense It couldn't hurt as well to release the IP before you disconnect it.. But I believe the first thing pfsense would try and do once it sees the connection again is renew which should fail because your a different mac, so it would then send a discover.. Which should get you a different IP.

Worked like a charm...thank you John!

@nollipfsense great - glad you got it sorted!
