[FreeBSD] Randomly Ether link down/up issue with "route -n monitor"(kernel Netlink enable /sbin/route ,14.x and later, some USB Ether interface)
[Change History]
2025/09/25 change [Reproduce Steps] from Wireguard to "route -n monitor"
2025/09/27 add NOTE 2(why so many ARP, request in this environment), NOTE3 and workaround
Reproduce Steps
- connect network
- start route -n monitor
- start iperf -s on other machine
- start iperf on target machine
#!/bin/sh
IPERF_SERVER_IP=[IPERF Server IP]
IPERF=/usr/local/bin/iperf
while [ true ]; do
${IPERF} -c ${IPERF_SERVER_IP} -e -i 1
sleep 1
${IPERF} -c ${IPERF_SERVER_IP} -u -e -i 1 --isochronous=60:100m,10m --realtime
sleep 1
done
expected Result
no link down/up on USB Ethernet(ue)
Result
sometime link down/up on USB Ethernet(ue)

[NOTE 1]
"route -n monitor" command is used on WireGuard(/usr/local/bin/wg-quick shell script)
[NOTE 2]
Here's the reason why so many "state REACHABLE" entries (one to two, or even more, per second) are being outputted by "route -n monitor" in this environment.
When the Ricoh ScanSnap application "ScanSnap Home" is running on a PC (192.168.10.198) and the ScanSnap scanner is powered off, the application sends ARP Request commands to search for the scanner. The FreeBSD box on same subnet reacts to these packets, and they are outputted by route -n monitor. (The application continues to send ARP Requests until it's force-closed).

tcpdump results:
14:12:00.058366 ARP, Request who-has 192.168.10.250 tell 192.168.10.198, length 50

14:12:00.058426 ARP, Request who-has 192.168.10.252 tell 192.168.10.198, length 50
route -n monitor results from roughly the same time:
14:12:00.512 PID 0 add/repl neigh 192.168.10.198 state REACHABLE lladdr 00:50:b6:nn:nn:nn iface ue0

14:12:00.059 PID 0 add/repl neigh 192.168.10.198 state REACHABLE lladdr 00:50:b6:nn:nn:nn iface ue0
Additionally, ARP Requests are also periodically occurring for a NAT server in the route that is currently offline.

14:18:08.711 PID 0 add/repl neigh 192.168.10.254 state REACHABLE lladdr 00:a0:de:nn:nn:nn iface ue0
[NOTE 3]
The issue (USB Ethernet link down/up) is that when an Ethernet driver without this problem (e.g., awg0) receives an ARP request, and NetLink processes it and reports it to route -n monitor, the affected USB Ethernet adapter (which is linked up and communicating separately) experiences a link down/up phenomenon despite not receiving the ARP packet on USB Ethernet.
Workaround
The root cause seems to be an issue between Netlink and the Ethernet Driver, but I don't have time to investigate it. Therefore, we're currently using the following workaround for FreeBSD-14 and later.
Workaround1 change /sbin/route

- Could changing the order of the interfaces shown by ifconfig from wg0 to ue0 solve the problem?
- Result: It won't solve it[NG].

[FreeBSD] use fib for specific wireguard interface
Background
My FreeBSD box has two interface, net0 is main fiber line(fast speed), net1 is backup line(Japan KDDI povo slow line).
At first, I set static route for backup wireguard line. Unfortenately, all packet to the static route([End Point IP address]) uses slow line[NG].
for Example previous config(/etc/rc.conf)
static_routes="backup_line"
route_backup_line="-net [End Point IP address] -gateway 192.168.220.1"
(192.168.220.1 is backup line default router)
Now I know the fib(Forwarding Informations Base), I use fib 1 for backup wireguard line.
Backup line is only used by below wireguard line[OK].
And I can remove above static route.
Step1: /etc/sysctl.conf
add below things into /etc/sysctl.conf(enable fibs)
net.fibs=2
net.add_addr_allfibs=1
Step2: /etc/rc.conf
# net1 is for fib1
ifconfig_ue0_name="net1"
ifconfig_net1="192.168.220.3/24 fib 1"
# set default route for fib 1
static_routes="fib1_default"
route_fib1_default="-fib 1 default -gateway 192.168.220.1"
Step3: /usr/local/etc/wireguard/wg0.conf
use PostUp line
[Interface]
Privatekey = [Privatekey]
Address = 10.8.41.1/24
table = off
ListenPort = 1111
PostUp = /sbin/ifconfig wg0 tunnelfib 1
[Peer]
PublicKey = IOx7n4S1rBZPlj6an2rMQSddj07RMQFkWPAyvtJsYnY=
AllowedIPs = 10.8.0.0/16, 192.168.0.0/24
Endpoint = [End Point IP address]:1111
PersistentKeepAlive = 30
NOTES:
When you uses multiple wireguard lines, if you want selectively to use net0(fast line)for one of wireguard line, you use wg*.conf without "PostUp = /sbin/ifconfig wg* tunnelfib 1".
