vpn-zone wide open
Hello!
I am using shorewall shorewall-2.0.11-1 on fedora core2
(iptables-1.2.9-95.7). My box has 2 physical nic´s plus one virt. ipsec
interface for a freeswan-vpn connection.
A few days ago, portsentry spit out a lot of connections from windows
clients (port 135, 445). Ooops.
I review my shorewall settings but could not find a mistake. So I took a

DNAT issue
Hi,
Sorry, not an experienced shorewall user, this is my first basic setup.
This starts to drive me crazy.
I wanted to use DNAT to forward port 33890 to an internal machine (windows)
port 3389. To reach my workstation when I''m not home.
In my rules :
DNAT:debug net loc:192.168.0.11:3389 tcp 33890 -
pub.lic.ip.add
#SECTION BLACKLIST
#well known port scans
DROP net

Shorewall and CUPS printing interference

Completely isolating P2P/BitTorrent traffic
Hi all,
I''m tring to isolate P2P traffic, specifically BitTorrent, for my QoS
scripts. I can''t seem to completely isolate ALL BitTorrent traffic.
I identify & mark packets and then use tc filters to put them into
appropriate classes. My firewall rules (below) do the markings. My VoIP
boxes'' and ICMP traffic get highest priority (mark 1). Then comes DNS, SSH,

Desktop Over NFS Home Blocked By Firewalld
Hi,
Just installed CentOS 7 that serves a home dir automounted over nfs.
SELinux is disabled. If I go to the client (oldish version of Fedora)
doing su - username works fine and the nfs export is mounted and I can
see all files and everything seems well. But trying to actually login
to the desktop from the client machine does not work. It starts to
login but then just hangs with a black screen.

IPSEC/L2TP Local and External Internet Access at same time through two interfaces?
Hey
First, apologies if this went out twice. I sent the original email from an odd email configuration (essentially from an alias of what I signed up as). I searched and noticed that my post did not appear and I did not get a bounce back so I was confused. I waited a few days before resending. So apologies if this goes out twice. I am not trying to spam.
I was hoping someone could help me with

Dev: new option to mark all tincd socket of a tincd process
I know i'm new to the list but i'd like to propose something for tincd

What could be the purpose of this new option?
The goal of this option is to be able to have several tincd process
