Howdy!
A quick question, is it possible for one NIC to use a different MAC
address on a different VLANs?
The longer version is that my ISP was kind enough to supply us with
three modems:
1) 100Mb bridge, with a static IP
2) 100Mb NAT gateway, with a DHCP assigned static IP
3) 15Mb bridge for VoIP, with a DHCP assigned IP
My pfSense box only has one interface, using VLANs to connect to the
modems through our managed switch.
#1 and #2 work fine, but I can't get #1 and #3 online together, when the
ISP sees the same MAC address on modem #1 and #3, it routes all traffic
to one modem or the other, despite the fact that they have different IP
addresses.
I'm hoping there's a way to override the MAC address on VLAN for modem
#3, but despite the field being available on VLAN interfaces, it doesn't
seem to apply.
Just to be clear, if I unplug either #1 or #3, or if I connect #3 to a
DHCP-assigned bridge on a different ISP, everything works. The IPs on
all three ranges are in different subnets, so there's no gateway
conflicts, as far as I can tell it's just the MAC address conflict.
Is there a better approach?
