Hi,

What are you talking about, ipchains, iptables, shorewall, etc?

[eddy_2]

i am new in linux debian.
if you tell where to search, i will be able to answer you

how did you configure your firewall? did you even install one or set up rules for one?

[eddy_2]

the problem that this server was already install by another person, and he left.

so now i didn't configure one and i didn't setup the rules

[coopstah13]

login as root and post output of

/sbin/iptables -L

[eddy_2]

i have these lines
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

[ursusca]

i have these lines
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

It means you didn't configure iptables.
Check out packages:

dpkg --get-selections | grep ipchains
dpkg --get-selections | grep iptables
dpkg --get-selections | grep  shorewall

you have no firewall running on this box, so the problem you are having is something else
