I'm running generic-pc-pb22r566 on a board with 3 RTL8100B (onboard version of RTL8139, yes I know
they're misfits) chips and a Via
I take a fresh image, set static IP on the WAN and LAN interface, and disable 'block private
networks' for this test. It routes
packets as it's supposed to.
Then I change the MAC address of the WAN interface and it ceases working. I then try to ping a host
on the WAN side from the webgui.
The host does receive the ARP request with the new MAC as source, and the ARP response looks good.
This is repeated 5 times, no ICMP
packet is ever sent, and the webgui replies with either 'the host is down' or just '100% packet

Rebooting the m0n0 does not make it work.
Removing the forced MAC does not make it work either -
Removing the forced MAC address and then rebooting does.
It's as if the NIC is still filtering to the old MAC address and can't hear the ARP replies to the
Q: I have a few ports that I want to return ICMP port unreachable packets. As far as I've read on
IPfilter, it does not support
sending back port unreachables, so I've mapped these to closed ports on a server. Is there a
cleaner, prettier way?
