IP tables confusion

[bayern1975]

Have you tried doing what I suggested?

did you mean change A to I like this? or something different?

iptables -I INPUT -p tcp -s 77.66.55.44 --dport 1234 -j ACCEPT
iptables -I INPUT -p tcp --dport 1234 -j REJECT

Yes, but you'll need to insert them in the correct order.

iptables -I INPUT 1 -p tcp -s 77.66.55.44 --dport 1234 -j ACCEPT
iptables -I INPUT 2 -p tcp --dport 1234 -j REJECT
