Harold,


Also the dynamic firewall filter compatible with fw4 (OpenWrt version 22.03.3+. NOTE: subversion 0, 1 and 2 had issues/bugs with  processing this script, use version 22.03.3+):

#!/bin/sh
# load encap.txt into ipipfilter list

PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin"

cd /tmp || exit 1

###########################

rm /tmp/ipip_filter.txt 2>/dev/null

echo 169.228.34.84 >> /tmp/ipip_filter.txt

grep addprivate /var/lib/ampr-ripd/encap.txt | sed -e 's/.*encap //' | sort -u | while read ip
do
        echo $ip >> /tmp/ipip_filter.txt
done

fw4 reload-sets

exit 0
