Mar 25, 2011I suspect this is an initial configuration bug. All firewall logs seem to be going to all
three files. That causes a lot of clutter in the log files, and makes it difficult to see whether there are any serious problems being logged.
Networking :: Setup Firewall / Sys1 Is Not Connected To Firewall For Testing Purpose?
May 18, 2010I am learning to setup firewall in my home for that i have selected four system(sys1,sys2....sys4) for testing .I have configured sys2 to act as a firewall with two NIC. sys3 and sys4 are inside the firewall . sys1 is not connected to firewall for testing purpose.
the IP assignments are follows :
sys1 : ( fedora, not connected to firewall i am thinking, But i am not sure )
IP : 192.168.2.1 ,
gateway : blank
dns1 : blank
dns2 : blank
sys2 firewall ,IPTABLES )
code....
what happened is that sys1(not connected to firewall) can ssh to sys4(connected,inside firewall),since the rules are written not to ssh form sys1 to sys4..
then I came to know whatever the request I give, It directly goes as sys1 --> sys4. Not as sys1-----> sys2(firewall)---> sys4 .and the firewall is not filtering and processing anything for both inbound and outbound (i think it's my mistake some where). the requests are directly going inside without firewall.
Software :: Build Firewall On Debian With 'Firewall Builder?
May 27, 2011I'm trying to build firewall on Debian with 'Firewall Builder'. But it won't let me compile and run unless one interface is set as management. There are two interfaces on my computer: 'eth0' and 'lo'
I don't want to be able to configure firewall remotely, so could I use 'lo' as 'management interface'?

General :: Ubuntu ICS Cut Off By Firewall?
Oct 7, 2010we're trying to build a simple Firewall/Gateway out of Ubuntu. We have a machine with 2 NICs running the latest version: 10.04.We have been able to set up the gateway/routing fine using both the built in Internet Connection Sharing as well as using Guidedog. The current setup we are testing is using Guidedog.For the NICs we have set eth0 as our internet connection and eth1 connects to the LAN. We've manually set all IPs...no DHCP at this time.
Next we try to install a firewall. We have tried both Firestarter and Guarddog. After setup with either, the Ubuntu box is still able to get online and access web sites but the LAN gets cut off. No access at all. We are currently running Guarddog and have set the proper protocols (DNS, HTTP, HTTPS) and have also followed the tutorial found here.
However, no matter what settings we make as soon as we re-enable the firewall the LAN is cut off. Disable the FW...LAN is back online. We even set up an "Allow All" protocol allowing all ports from 1:65535 and still we get cut off as soon as the FW is enabled.
We saw this same thing happen with Firestarter and my understanding is they're using the same basic Linux FW underneath? SO, what is it we're neglecting to do? Why does the FW completely seal off our LAN connection no matter what we've told it to allow?
Ultimately, here's the layout we're after:
Internet (T1) <> Firewalled Ubuntu <> LAN
General :: SSH Tunneling For Bypassing Firewall
Aug 4, 2010I am on Linux on machine LOCAL (my notebook).I ssh into a company machine REMOTE which is behind a firewall and ONLY allows incoming ssh connections (port 22), no outbound connections whatsoever. I do have full root access on both, LOCAL and REMOTE, REMOTE is however a VPS and behind a hardware firewall.I now need network access on REMOTE (HTTP and other protocols) for downloading and building some software. I also need to access to NON HTTP protocols such as git.
I was hoping to set up a reverse SSH tunnel for using my LOCAL machine, where I could be running a socks server. So that network access on REMOTE would be redirected over the SSH tunnel to a socks server running on machine LOCAL.How would I go about setting something like this up?
General :: Best GUI Based Firewall For Ubuntu?

View 2 Replies View RelatedGeneral :: Recommendation For Firewall Server?
Apr 1, 2009After metering the power being used daily in my computer room, I decided that I needed to get somewhat greener. So I am updating all my equipment and getting rid of the old towers and power hungry equipment. So far so good, except for the box running Smoothwall.
It is an old IBM 300GL from the '90s that is apparently never going to die. But it is noisy and not exactly low powered and has to be on all the time. The only machines that I have presently that can be used as a replacement are full blown AMD 3000 and 6000's, and I hate to waste one of those just to be a firewall. I can find some mini cube systems that are very low powered - some even run on just a wall cube - but can't find one with two ethernet ports, and of course there is no plugin buss on a tiny box.

Feb 8, 2010i have a linux server runnig oracle applications. i need to access this server from putty using ssh through internet. i did by registering my static ip with the dnydns.org and i am able to connect to the server. but now there is no security to authenticate any user as any one knowing the password can login to it. i thought of configuring the firewall of linux server but the client ip`s are not static and they change continiously. so thought of keeping one more pc between the server and the router which will do the work of authenticating. but i am confuse as how to configure it to allow the packets coming from the internet after authenticating and to by pass the packets generated from internal LAN?
i have heared abut freeradius package but i am not sure will it work in my case?

View 1 Replies View RelatedGeneral :: Windows - Establishing A VNC Connection Through A Firewall?
Jun 28, 2010What's the best way to establish a VNC connection to a computer located behind a firewall/router, to which you don't have access? I have a home Linux computer on a Comcast connection, which explicitly blocks incoming requests, so I can't hit the IP directly, but I'd like to remote into it from an arbitrary Internet connection. How would I work around this?
I've witnessed some commercial products, such as one employed by Dell tech support, which appears to use a public web server, which you visit from the target computer in order to "expose" it to an incoming VNC connection. Is there anything similar that's free/cheap for personal use?
General :: Removing / Disabling Firewall Happens Temporarily
Apr 16, 2011I tried following the instructions in this link to disable and remove iptables firewall using commands:
# service iptables save
# service iptables stop
# chkconfig iptables off
# iptables -F
# iptables -X
# iptables -t nat -F
# iptables -t nat -X
# iptables -t mangle -F
# iptables -t mangle -X
# iptables -P INPUT ACCEPT
# iptables -P OUTPUT ACCEPT
Its seems to work temporarily and then the firewall gets enabled again by itself even without restarting.
