hi all
Im taking care of a fw machine that is configured by my predecsssor,
firewall being configure by default policies to ACCEPT for all chain
(coz he thinks its difficult of an ISP to run firewall as default set
to DROP)
however for the time being this is not my concern but here are few
lines from script that confusing for me
iptables -A INPUT -p TCP -s 0/0 -d 0/0 --dport 1025 -j DROP
iptables -A FORWARD -p TCP -s 0/0 -d 0/0 --dport 1025 -j DROP
iptables -A OUTPUT -p TCP -s 0/0 -d 0/0 --dport 1025 -j DROP
when I do "tail -f /var/log/messages", I found lot of below messages
Sep 20 12:26:35 guru named[12308]: client xxx.xx.xxx.xx#1025: error
sending response: host unreachable
Sep 20 12:26:37 guru named[12308]: client xxx.xx.xxx.xxx#1025: error

Sep 20 12:26:37 guru named[12308]: client xxx.xx.xxx.xx#1025: error
sending response: host unreachable
Sep 20 12:26:38 guru named[12308]: client xxx.xx.xxx.xx#1025: error
sending response: host unreachable
Sep 20 12:26:39 guru named[12308]: client xxx.xx.xxx.xxx#1025: error
sending response: host unreachable
what mean by all this, can someone care to explain/clear things to me? :)
may I remove the above iptables rules?
regards
Askar
