shorewall 2.0.3a, (ULOG) doesn''t log anything
Dear all:
Im using shorewall 2.0.3a (debian) w/ ULOG. shorewall starts ok, and the
firewall is running, but nothing is printed on the logs.
I try, for example, to do a connection to a port that is opened on the
server but closed by the FW and I get a connection refused. If I stop
the firewall, this port is accesible from the outside.

Troubles DNATing UDP
Hi.
I have strange troubles with DNATing UDP packets.
The situation:
1. We have local network 10.10.0.0/16
2. We have a "server network" 192.168.1.0/25 connected with local
network by a router 10.10.100.1 (other ip 192.168.1.1).
3. Web server is located at 192.168.1.2
4. There are HW pingers in the net 10.10.0.0/16 whose do ping
10.10.100.1 every second. The ping is the UDP packet

Extend DHCP range
I have a simple DHCP range .
option routers 192.168.1.1;
subnet 192.168.1.0 netmask 255.255.255.0 {
range 192.168.1.60 192.168.1.129;
range 192.168.1.150 192.168.1.199;
}
So I want to add a range 192.168.2.1 -> 192.168.2.254
so I did this:
subnet 192.168.1.0 netmask 255.255.254.0 {
range 192.168.1.60 192.168.1.129;
range 192.168.1.150 192.168.1.199;

Can login but can't add a machine to AD.
I'm finally moving to ad, after way way too long. I did the classic
upgrade, and my existing PC's all can log in fine. I can make new user
accounts, and log in on those machines fine. My ddns (with bindz) seems
to be working, and I do see
new ip addresses pop up in there.
The problem is I can't add a new Windows machine to the domain. When I

Hi All.
This has got me stumped!!!

All is working fine on my sample platform, except that I have plenty (several thousands) of users that login using local_part#domain, instead of local_part at domain, which is an old setting on my POP3 server. And in that case, Dovecot returns 'Authentication failed'.

problem getting ulogd and shorewall working on debian
I''m trying to get Shorewall to use ulogd for logging, but I''m not

I''m using the kernel 2.6.6, iproute2-2.4.7.20020116, iptables v1.2.9, and gentoo.

Any help will be appreciated
