Subject: [0/4] use true mac address of LAN local remote hosts
Date: Fri, 6 Jun 2025 21:11:47 -0400 [thread overview]
Message-ID: <20250607011151.3290866-1-jmaloy@redhat.com> (raw)
Bug #120 asks us to use the true MAC addresses of LAN local
remote hosts, since some programs use this information.
These commits introduces this for ARP, NTP, UDP and TCP,
while it is still missing for ICMP.
Jon Maloy (4):
netlink: Add function to extract mac addresses from arp table
arp: respond with true mac address of LAN local remote hosts
udp: forward external source mac address through tap interface
tcp: forward external source mac address through tap interface
