Jun 3, 2010I want to find out which server/service a streaming box connects to and maybe also take a look at some packets. The box connects to the Internet via a Linux gateway running Debian I have root access to. I have some basic knowledge about iptables, tcpdump, netstat etc. but couldn't yet figure out how to get this info.
My first approach was with netstat, but this traffic seems not to be visible (which somehow makes sense to me). My next guess was that with iptables it should be possible to log this connections, however I couldn't yet figure out how to.
General :: Backup / Setup A Second VPN Tunnel On A Fallback Gateway / Firewall On The Client Side
Mar 1, 2011I've set up a Lan-to-Lan (routed) OpenVPN tunnel. For redundancy I want to set up a second VPN tunnel on a fallback gateway/firewall on the client side. Currently, both sides (server/client) know how to route packets across each others physical LAN. So no NAT is used. When the primary gateway (fw1) is connected to the VPN server all traffic runs via the fw1 tunnel. Than when the secondary gateway (fw2) connects to the VPN server and fw1 is still connected all traffic for fw1 will be delivered to fw2 and effectively destroying traffic intended for fw1. This is of course no problem if I first shutdown (fence) fw1, than set up fw2 to use the gateway IP address from fw1 and set up the VPN tunnel to the VPN server. Effectively replacing fw1 with fw2 on the client side.
However, I can't seem to find a decent howto.
I am also exploring the possibility to let both tunnels active and let OpenVPN (or another tool) decide how to route packets back and forth the different LANs. A virtual IP between two gateway's both running a VPN or something similar. This would be the preferred method of course. However, I don't know how to tackle this one but I'm pretty sure there are people out there who are happy to share their 2 cents.

Jul 25, 2011I have users using Windows XP, Windows 7, Linux (Fedora) and Mac. They all are in a single private network and all access internet through a Linux (RHEL5) system in which Squid acts as gateway. The same is true with my branch offices too except that private network is different and gateway system uses Fedora 9 instead of RHEL5. All the branch offices are connected through point to point leased lines with the head office for file transfer.
My requirement is this: I have a web server located at head office. Presently I am able to access this server from my branch offices through internet. I would like to access this server from branch offices through leased lines. This too I am able to access if I do routing in users system. The file transfer is taking place through one to one system at two ends by creating static routing in those systems.
Networking :: Routing For A VPN Gateway Setup?
Dec 17, 2010I've been trying to setup an IPSec connection between two routers, but am having trouble with the actual packet routing.
My setup currently is two local networks (192.168.1.0/24[netLANA] and 192.168.0.0/24[netLANB]) that are connected to their own routers (192.168.1.1 and 192.168.0.1 respectively). The routers are both connected to the 194.26.1.0/24[netWAN] network. I wish to setup an IPSec connection between the two routers, to act in tunnel mode between the two local networks.
The first router is a linux box (on the netLANA network) that I am setting up using the ipsec-tools, and the other is a Netgear ProSafe FVS318G (on the netLANB). I've set them both up to have the same configuration for IPSec. Also, on the linux router I have setup a route like this:
Code:
$ route add -net 192.168.1.0/24 wlan0
So that all traffic destined for the netLANB network will be routed to the wlan0 interface (netWAN in this case, and therefore over the tunnel).
My problem is that if I ping from any host on netLANA, I can see the ICMP reply comes back to the linux router, but it doesn't get back to the original host.
From the linux router, here is the tcpdump of the ping:
Code:
$ tcpdump -n -S -i any
17:06:26.308353 IP 192.168.0.5 > 192.168.1.4: ICMP echo request, id 1036, seq 1, length 64

Networking :: Cannot Seem To Setup Gateway To Route Properly
Jul 24, 2011I have setup a second machine with slackware 13.37, it is a "supermicro" which I picked up though my work. the idea was to set it up as a gateway and gradually expand my knowledge of sub networking, iptables, forwarding and the like. after a couple nights of forum searching and "o'reilly" book reading I am still unable to get a proper route working thru the "supermicro" to our dsl router.
What is setup?: I will start from my main machine simply calling it slackbox
slackbox: has two ethernet cards which i have given static ip's to
eth0 192.168.2.16 and eth1 192.168.3.11
eth0 (192.168.2.16) is connected to a switch and then to our dsl router, it is working, I am using right now to work on this forum.
eth1 (192.168.3.11) is connected to the "supermicro" thru a cross-over cable, it also is working, pinging the "supermicro" works.
default gateway on slackbox is set to be 192.168.3.10 (the supermicro)
I only set slackbox's default as 192.168.3.10 when testing to see if the supermicro gateway will work
supermicro: also has two ethernet cards which i have given static ip's to
eth0 192.168.3.10 (this is the card with the cross-over cable connected)
pinging 192.168.3.11 (the slackbox) works.
eth1 192.168.2.24 is connected to our switch as well, it is working, pinging our dsl router works.
default gateway on supermicro is set in rc.inet.conf to be 192.168.2.1 (which is our dsl router)
All my machines have two ethernet cards. This has just made it easy for me to test the setup while still having internet access on slackbox. Yet when testing the gateway from slackbox thru supermicro I am getting "Destination Host Unreachable".
Networking :: Setup 2 Gateway For Email Server
May 11, 2010setup 2 gateway in my email server(opensuse).
now i wan to setup 2 internet lines for my email server, which mean that either one of the line is down, i still can receive mail from another line.
Example
Internet line 1 = ISP1
Internet line 2 = ISP2
my email server got 3 nic which...
eth0 = 192.168.1.2 (255.255.255.0) (from ISP1 GW 192.168.1.1)
eth1 = 192.168.2.2 (255.255.255.0) (from ISP2 GW 192.168..2.1)
eth2 = 168.168.1.2 (255.255.0.0) (connect to local LAN)
now existing GW set on the server is 192.168.1.1, mail receive and send through ISP1. now we wish to set somethings that once the ISP1 line is down, the server will auto switch to ISP2 gateway and continue send and receive mail without manually change of settings

OpenSUSE Network :: Unable To Ping The Default Gateway When Using Custom Settings - Unreachable Network

May 29, 2011I have been searching google for a while now and have not found exactly what I am looking for. I would like to use my fresh install of ubuntu server 11.04 as my router/gateway for my home. I am not an expert at linux by any means but I can usually figure stuff out. I believe I need iptables, bind, and a few others probally. It eventually will also be a samba server but I have done a little with samba before. I do have 2 network cards, my router at the moment is starting to die and would love to have a more powerful router. I would also like to figure out how to do port forwarding in the router, as well as be able to see the load on the network cards. Maybe there is a program to show usage by user? As well as be able to do packet pritorization.

OpenSUSE Network :: Using As A Network Gateway - Renew DHCP Lease
Jul 15, 2010Why trying to avoid ranting about my Linksys router, I'll try and keep things short. I have a Linksys router in which the default firmware was terrible and would not correctly renew its DHCP lease. After getting feed up with that I flashed dd-wrt on the router and now it works better but randomly DNS queries would stop being resolved. To rule out the chances that it is my ISPs DNS servers I switched my DNS to openDNS, same problem happens (although I have to admit openDNS is a lot better than what my ISP has).
Anyways I'm about feed up with it and about an inch away from drop kicking the thing out my window. To avoid that I figured I will give it one more change and instead of using my Linksys as my network gateway I'll move all of that to my home server, and make the Linksys just an wireless AP. Besides setting up DHCP, DNS, and iptables on the server is there anything else I will need to know and setup on the server to make this work?
Side note anyone using openSUSE for DHCP know if setting up reserved IPs for certain MAC address is possible?
Ubuntu Networking :: Setup Routes For A Gateway That Resides On A Different Subnet
Jul 29, 2011I'm trying to setup routes for a gateway that resides on a different subnet. Our ISP leased us a block of IPs and told us to route through the current gateway, which is on a different subnet than our current block of addresses. To test, I've enabled one of the new addresses on one of the existing machines, which works. That machine has an address on the same subnet as the gateway, however.
The gateway address is 24.111.1.177 One of the new addresses I'm trying to use is 96.2.192.130, netmask= 255.255.255.240, broadcast= 96.2.192.143 Obviously, I can't just specify that gateway in /etc/network/interfaces without some routing, which is where the trouble I'm having is. The machine I'm trying to set this up on is part of 2 networks - one internal, on two different NICs.

View 2 Replies View RelatedNetworking :: Creating Simultaneous Network Connections To A VPN And Local Area Network?
May 31, 2010I'm working with a Ubuntu 10.04 LTS system with two network interfaces (both Ethernet). I wish to setup this system such that it is simultaneously connected to my local and an OpenVPN network and able direct traffic between the connections depending on what program is sending the traffic. The problem: Under my current OpenVPN configuration all network traffic is directed to the VPN.
My OpenVPN config file (some details omitted)
--remote [gateway ip] # vpn12 load:
--remote [gateway ip] # vpn11 load:
--remote [gateway ip] # vpn15 load:
--remote [gateway ip] # vpn16 load:
[code]....
In practice, I would like OpenVPN to operate out of one of my two network interfaces and leave the other interface connected to the local network. Then by default all network traffic should be directed to my local network unless I specify (on a per program bases) that certain traffic should go though the VPN. These two network connections can (should) stay completely independent of each other and do not need to talk to each other.
OpenSUSE Network :: No Internet After Install Of 11.4 Network Connections Fine

I first tried an upgrade from 11.3 to 11.4 and lost Internet Access, so i re-loaded 11.4 from scratch on clean partitions.
I am connected to my wireless WPA2/PSK connection, have an IP, am able to see the network.
I turned off and disabled the SUSE firewall.
I tried setting Firefox proxy settings to auto and to none, i dont use proxy.
I am currently posting this through an SSH connection to my 11.1 server from the new install of 11.4 on a Dell latitude D600 laptop (not using the on-board Broadcomm that is an issue for a later date).

View 9 Replies View RelatedFedora :: Control Of Network Connections/network Startup - 9 Gnome?
Jan 5, 2009I have my box setup as a router/NAT with two different network cards. One for external connection(connected to the Cable Modem) one for internal connection(used for internal DHCP). It works perfectly when I manually activate the two interfaces after booting(both interfaces always show up as inactive after booting), then the DHCP server and firewall. I am confused, however, by which program has control of these interfaces.
First, there is the Network Configuration (System->Administration->Network), which is where I manually start the interfaces after rebooting. Both interfaces are set to "Activate when computer starts" in here.
Second, Network Device control(System->Administration->Network Device Control), which looks to be almost the same thing as the above.
Third, the NetworkManager applet(on the top bar) - both devices show up as unmanaged when I left click on this, but if I set "Controlled by Network Manager" in the "Network configuration" window(number one above), It still does not work. Can I get rid of two of these programs, or is there some way to edit the startup scripts to start my ethernet cards before the dhcp server/firewall(which is shorewall BTW)?
