pfSense

how to do that coz i have just one nic and 4 VLANS configured on it, 2 WAN and 2 LAN

Are just VLANs assigned to interfaces (WAN, LAN, OPTx) or the parent nic is also assigned to any interface?

Just 4 vlans, 2 wan and 2 lan

first i create new vlans, like 10.20 etc for the parent single mac id, then assign wan interface to one of them like vlan20, then i goto wan interface and set as pppoe and in the MAC address field i put the spoofed mac id which i want and then connect my pppoe but isp still the original physical nics mac id.

i was reading in the forum etc on this and it was mentioned that the main physical interface needs to be in promiscuous mode but if i do that then wouldnt it affect network performance?

im using multi wan but on same isp which needs my mac id but when both the wans are connected, the isp see the main actual mac id, i want to be able to spoof mac id on one of the connections so for wan1 they see the actual nics mac id which is by default and then on wan2 the spoofed mac id but the pfsense box has one nic so i need to use vlans only

and also sometime back i saw some patches which make all vlans use the parent nic mac id only so if the parent nic mac id was changed then all vlans would use that rather than use the parent mac id by default for all vlans except on the one it was spoofed with a different one

All VLANs will have the same mac address set, you cannot have 2 VLANs (on the same physical interface) with different mac address.

but based on this thread, there r a few ppl using it but with promiscuous mode on and i did the same and isp authorizes fine and downlaod speeds are fine, upload seems weak but im still tracing that if its something with isp or something in pfsense

practically is this even possible?

feature request would push it forward for a few months to over an year now, probably if there was an answer to it being possible then i would try and get funds to have this feature done sooner

there could be 2 ways to do this

register multiple mac ids using network drivers
or
bridge the interface and then change mac id on the bridge

Yes, it's something possible to do, but requires work on GUI and backend to properly enable promiscuous mode on interface and let user know it's happening. There are 2 ways to get it done faster, make the change yourself and send us a pull request at github or funding the development. I estimate it'll take about 10 hours of work to setup a test environment, develop and test the solution.

and total cost of solution would be because when i tried promiscuous mode, my download got faster bu upload was still slow and i had it checked with the isp and there was still some parent mac id fragments causing this so basically promiscuous mode itself doesnt solve it and needs more backend work as well
