SHOREWALL
You can turn off on shorewall.conf
LOG_MARTIANS=No
KERNEL
You can turn off martian logging:
echo 0 > /proc/sys/net/ipv4/conf/{all,default}/log_martians

Hi,
I'm a long time shorewall user, but with very basic skills, running a
simple 2 port firewall between my ISP and a home network.
Home network is on 192.168.0.x
My wife has configured her laptop NIC with both a 192.168 address and
a 172.16.x address, so that she can connect to a private development
system at her office (this system uses static IPs only).
This means that when she connects at home the firewall machine log is
flooded with kernel warnings about 172.16 martian packets.
I can disable these warnings in the shorewall log but they still
appear in the system log (journalctl).
Can I use shorewall to drop them before the kernel sees them? or is
there some other way of cleaning up the log?
Thanks for any help.
