hi,
if it is recomended to comment out this rules:
-------------------------------
num target prot opt source destination

#7 REJECT tcp -- anywhere anywhere tcp dpts:0:1023
flags:SYN,RST,ACK/SYN reject-with icmp-port-unreachable

#8 REJECT tcp -- anywhere anywhere tcp dpt:nfs
flags:SYN,RST,ACK/SYN reject-with icmp-port-unreachable

#9 REJECT udp -- anywhere anywhere udp dpts:0:1023 reject-with

#10 REJECT udp -- anywhere anywhere udp dpt:nfs reject-with
icmp-port-unreachable

#11 REJECT tcp -- anywhere anywhere tcp dpts:x11:6009

#12 REJECT tcp -- anywhere anywhere tcp dpt:xfs
