You can consider upgrading to Solr 8.5 which is to be released in a couple of days, which makes it easy to whitelist IP addresses in solr.in.sh:
# Allow IPv4/IPv6 localhost, the 192.168.0.x IPv4 network, and 2000:123:4:5:: IPv6 network. SOLR_IP_WHITELIST="127.0.0.1, [::1], 192.168.0.0/24, [2000:123:4:5::]/64" https://lucene.apache.org/solr/guide/8_5/securing-solr.html#enable-ip-access-control But please please do not expose Solr, even if secured, to untrusted networks and never to the public internet.
