Software :: Forward Out The The Outiside Interface To Get To The Internet?
Jan 27, 2011
I'm interested in installing Privoxy on CentOS. I have two nics and would like to setup this on my network. One nic will be inside and all computers will use the inside address to get to the proxy. The other nic will connect to my FW and forward traffic to the internet.
I understand I need to change config file for the listening ip "inside ip:8118", but how do I forward out the the outiside interface to get to the internet? Does Privoxy just pass the DNS request like web traffic?

I'm a student who is working on a wireless research project. I have a madwifi driver for Atheros chipset on Debian Linux. With having the wireless interface get into monitor mode, I want to forward the captured packets from the wireless interface to the other Ethernet interface so that a different computer which is connected to this machine via Ethernet receives those packets. I checked that alll packets are received in the wireless interface using TCPDUMP. I tried to forward those packets with IPTABLES like 'iptables -p FORWARD -i ath0 -o eth2 -j ACCEPT' However, I couldn't see any packets forwarded to eth2 using TCPDUMP.

What I am trying to do: bridge 2 NICs in my linux box eth0 connects to linsys router (which in turn connects to internet) eth1 connects to Xbox 360
What I did:
Code:
ifconfig eth0 0.0.0.0
ifconfig eth1 0.0.0.0
brctl addbr br0
brctl addif eth0
brctl addif eth1
[Code]...
I'm sure this is a bridging issue and there is just some option I'm not setting correctly. Also, the reason I'm connecting the Xbox 360 directly to the linux box and not to the router is for traffic monitoring purposes. Note that all connections and functionality work perfectly when the Xbox IS connected through the router.

While I have Transmission running, whether it be up/downloading or just open with one thing unpaused and no activity, all other computer functions that need internet access are unusable. Transmission says my port is closed in its preferences.
1. How do I find and open port?
2. Will finding an open port solve the problem of all things internet not working while Transmission is?
3. Do I need to create a static ip in order to forward a port through my router?
4. Will creating a static ip and forwarding that port solve my problem of only being able to use the internet while Transmission is on?

I have a computer who has a wireless card I use for my local network and Internet. I have a second network card on this computer (onboard lan card), that I would like to use to forward an Internet connection to a older-generation laptop computer.
Main Computer Connection to Internet:
Internet > Wireless Router > Computer A
Laptop Computer:
Computer A > Laptop (via cat5 cable connecting my main computer to the laptop)

When I do...# iptables -L...I see rules in my INPUT and OUTPUT chains that look scary:ACCEPT all -- anywhere anywhere...but these rules only apply to the loopback interface. I tested it and the server cannot be reached on open ports from the outside world. How can I make iptables show the interfaces that the rules apply to?Otherwise, every time I do iptables -L it will scare the crap out of me.

I found multiple sites explaining how to add IPs to a network interface as virtual interface like eth0:0. However I can add IPs to an interface as well using the ip command: ip a a 192.168.2.2/24 dev eth0 What I want to know is how I can make this persistent on rhel/centos.

The following are the output of command "ifconfig -a":

The interface "eth0", which is down, was not displayed, but loopback interface has been displayed. So, how can I make my application display all interfaces, including the interfaces which are down, but excluding the loopback interface?

I have two IP address on my iMac I want to "bridge". I'm not sure what the proper terminology is... here's the situation.
My iMac has a firewire connection to my laptop and an ethernet connection to the rest of my office. My laptop has an ip of 192.168.100.2 (on the firewire interface). My iMac has an IP of 192.168.100.1 on the firewire interface, and two IPs, 10.1.0.6 and 10.1.0.7, on it's ethernet interface.
If I wanted to forward all traffic coming in from 192.168.100.2 on my OS X machine to go out on IP 10.1.0.7, and vice-versa, can this be done? I assume I would use the ipfw command.
Essentially I want to "bridge" the firewire network to the ethernet network so my laptop can see all the machines on the 10.1 network, and all those machines can see my laptop at 10.1.0.7. Is this possible?

I'm trying to forward VNC requests from server a to server b, acctually I need the server a to be just VNC proxy and other servers behind server a can be responsible for VNC requests.I did it with this iptables rule but it didn't workAnd for notification all VNC sessions of mine are in range of 59100 to 59199
num target prot opt source destination
1 DNAT tcp -- 0.0.0.0/0 0.0.0.0/0 tcp dpts:59100:59199 to:bbb.bbb.bbb.bbb
Do you know a better way or a way to fix it with iptables?

I have a computer with a BSD subsystem that is acting as a router to other Windows computers.
On one of my Windows, I have an Apache Web Server that I want people to access from the outside world.
So, I have created an ipfw rule in my router computer that goes like this: ipfw add 100 fwd 10.0.2.2 ip from any to any dst-port 2443
Thing is, nothing happens.
I've tried changing the ServerName in my Apache to match my IP address (which is the destination IP of the incoming packets, I imagine) but still, nothing.

My kind isp had set up a authoratitive dns server that can't be cancelled that points to the wrong ip address. Hence I need to take all the traffic going into server A at the ip address aa.aa.aa.aa and send it all onto server B at ip address bb.bb.bb.bb. After much head scratching, I managed to achieve it as follows:- On the server at ip address A, set up following :-
iptables -t nat -A PREROUTING -d aa.aa.aa.aa -j DNAT --to bb.bb.bb.bb
iptables -t nat -A POSTROUTING -d bb.bb.bb.bb -j MASQUERADE

I know I've done this before but I haven't had the need in awhile and it escapes me what I did. Basically, I have a box with a ssh service with X11 Forward on. I can connect, initiate a process on the remote box, and see the program as if on the local one - all good.What I would like to do, though, is say I fire up a process - lets say a cdburn from a gui and not a cli on the ssh service box. Then I go to a remote box and ssh into the one burning the cd. I'd like to pull what is being displayed on the remote box to the local box so that I can see the progress - without looking at text log files - I want the actual display.This is just a simple example of more I want to do, so getting the actual display as an interactive display is critical. I seem to remember something about finding the process id and connecting to that, but again its been years and I forget.The other option would be to forward the entire screen, sort of how windows does remote desktop, but I'd prefer on a process by process basis if possible.
