hello,
i'll try to solve ur prob....
u must go to rootprompt n simply flush all the iptable enabled rules..........
u can check this by......#iptables -L
THIS WILL SHOW U THE LIST OF FIREWALL RULES ENABLED....
now to turn off these..........flush all
by.......#iptables -F
n to delete any user defined chains use -x (chain name........)
that u kan conferm from first command if u find any name other than input ,output,n forward then that shld b user defined so delete it..........
now check again thru #iptables -L
U SHLD FiND........
[root@localhost root]# iptables -L
Chain INPUT (policy ACCEPT)
target prot opt source destination
Chain FORWARD (policy ACCEPT)
target prot opt source destination
Chain OUTPUT (policy ACCEPT)
target prot opt source destination
[root@localhost root]#
IF U FIND LIKE THIS THAN ur firewall rules have been disabled..............
hope this'll work
good luck
