192.168.1.0/24 -- is this the source address packets are sent from?

I'd recommend a step-by-step setup-procedure (at least I did until I
knew).

iptables -P INPUT DROP
iptables -A INPUT -j LOG --log-level info --log-prefix IPT_INIT
iptables -A INPUT -s 192.168.1.0/24 -j ACCEPT
iptables -A INPUT -j LOG --log-level info --log-prefix IPT_EXIT

tail -f /var/log/kern.log 

HTH.

wbr,
