[root@RHIS-GAIA-RPT01 mtadmin]# service iptables status

Table: filter

Chain INPUT (policy ACCEPT)

num target prot opt source destination

1 ACCEPT all -- 0.0.0.0/0 0.0.0.0/0 state RELATED, ESTABLISHED

2 ACCEPT icmp -- 0.0.0.0/0 0.0.0.0/0

3 ACCEPT all -- 0.0.0.0/0 0.0.0.0/0

4 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 state NEW tcp dpt:22

5 REJECT all -- 0.0.0.0/0 0.0.0.0/0 reject-with ic mp-host-prohibited

Chain FORWARD (policy ACCEPT)

num target prot opt source destination

1 REJECT all -- 0.0.0.0/0 0.0.0.0/0 reject-with ic mp-host-prohibited

Chain OUTPUT (policy ACCEPT)

num target prot opt source destination

Is there a way I can allow only specific ports through the firewall? For example port 1521, instead of completely disabling the firewall.

Regards,

Joe
