Debian :: Setup Dnsmasq On A Network That Already Has A Router?
Feb 17, 2010
I am trying to get more control of my small office network. It consists of several windows workstations, a debian box, and a ZyXEL P-660HW-D1 router, Right now, the only way to reach the debian box from other computers is to type in its ip address.
The goal is to be able to reach the box by just typing ://debianBox into my browser, though ideally I want to set it up to be something like ://debianBox.officenet, and to also reach other people's computers by typing ://mattBox.officenet and ://fredBox.officenet
The Zyxel router has a LAN page with a DHCP Setup tab with fields setup like so In the past I was able to mange this using an Orange router, but now I have to use the ZyXel.
So I installed dnsmasq on the debianBox, but I do not know how to configure it to get the results. I want and still get internet fromthe Zyxel router.
In the etc/hosts file of the debian box I added 192.168.69.15 debianBox, and for testing on my windows machine I set the primary dns entry of the Ip4 connection to 192.168.69.15 as well, but typing ://debianBox in my browser still gives me not found.

I'm having trouble getting my network set up the way that I want it/had it. You see, when I first set up my network, I just had my cable modem going directly to my standard wired router (A D-Link DI-604), which had DHCP,and was connected to all of the computers on my network. I had one switch hooked up to one of the ports of the router, but this was a regular switch, and it would not try to assign IP addresses, it would just pass through the DHCP info as I wanted.
Now however, my network setup has changed. My room mate and I both got laptops, and we decided that we wanted to have wireless access so we didn't have to constantly plug in to the router.
Now my network is set up like this: The modem is hooked up to the router(DI-604), which is hooked up on the LAN side to our computers, our switch (which is hooked up to 3 more computers), and to a wireless router card (A Gigabyte GN-BC01).
The wireless router card has two jacks for ethernet. One for WAN, and one for LAN. The LAN side we have plugged only into the computer in which the card is installed.
Now the problem is this: The wireless router card comes with DHCP by default, and it's assigning addresses to the laptops and to the computer hat it's in, and worse, the IP addresses are on a different subnet than that of the main dlink router. The Main (dlink) router assigns addresses from 192.168.0.1 (itself) to 192.168.0.254, while the wireless router card assigns addresses from 192.168.1.1 to 192.168.1.254 (itself).
Because of this, I cannot access services on the wireless network from my wired network or vice versa. The first thing I tried was setting the card to assign addresses from 192.168.0.12 to 192.168.0.253, however it just said "internal error" when I tried to do this. I decided that this may be because it sees that it was being assigned an address on it's WAN side on the same subnet. So the next thing I tried was disabling DHCP and setting the "LAN IP Address" to 192.168.0.12, hoping that the DHCP would just go through the card, like a switch. I would have set the LAN IP address to be assigned by DHCP, but this was not an option, so I decided that'd be the best thing to set it to.
Once again however, setting the LAN ip address to an address on the same subnet as that of the IP assigned to it's WAN side caused it to report an "internal error". I verified that this was the issue by setting the LAN address to several other private IP addresses to test (I.E. 10.0.0.1, 192.168.3.1, 192.168.5.12).
My question then really is: How do I set up both routers so that I can access services and computers from each network from the other network. Should I set them with different subnets and set the gateway on the wireless network to the main router? To the wireless router card? Should I put them on the same subnet? Will it know how to communicate?

Is it possible to setup DNSMASQ so that it respects the TTL it is given by the upstream DNS server, but it sends out a fixed TTL to its clients?My DNSMASQ server is running on the same local network as all its clients. I want all my clients to be served with a 5 minute TTL, regardless of what the actual domain uses. So for instance if google.com has a ttl of 60 minutes, then I want DNSMASQ to cache it for 60 minutes, but I want my clients to receive a TTL of 5 minutes so that they query my DNSMASQ server again every 5 minutes. I basically want to avoid having each client's OS doing any caching.

I have an adsl modem acting as a bridge to my router my setup was working well for more than year now , but then the internet went slow . I set the modem back to PPPoE the problem was with the DNS server of the ISP so using ifup i set the dns t 8.8.8.8 (google) the connection is back , but when i set the modem back as a bridge slow internet does the router know that my dns is 8.8.8.8 or i should set the dns on the router ? I can't see an option to set the dns on the router ( i just enter my username and password from the isp to use PPPoE mode ) by the way i called the isp support they kept telling me to restart , i told them i did but i never restarted my pc . I'm sure if i tell them i'm running linux they will blame the os !

My upstream DNS server is a bit slow, so I've installed the dnsmasq cacher locally. I have the service starting on runlevels 2, 3, and 5. But I can tell by Firefox's behavior that dnsmasq does not work upon boot. Firefox lets its own DNS cache expire after 60 seconds. When I do my second Google search five minutes after my first, the second DNS lookup for www.google.com is just as slow as the first.If I manually restart the dnsmasq service, I get the fast name resolutions I expect.

I installed dnsmasq to speed up dns querry for my network. i didn't really change any thing in my dnsmasq.conf file. i only just put my upstream dns addresses in resolv.conf. i have dchp running and configured to issue the ip address of the system running dnsmasq as dns ip to the dhcp clients. But i have noticed that if i do ipconfig /all on my windows clients, instead of the dnsmasq server ip showing, i still see the dns ip of my upstream provider. by this, iam assuming that the client are not using the cache even though the service is running on the server.

I'm try to setup a wireless network with my linksys wireless router and my HP laptop dual booting Vista & Suse 11.2. I have the vista networked, just fine. Where I can share files and the printer connected to my desktop. But I want to be able to use Suse in the same way, full time and to stray away from Vista. My wife and kids like easy. So I'm trying to transform them and show them something new.

I have a DNS server (dnsmasq v2.55) at the center of three subnets: x.y.1.0/24, x.y.2.0/24 & x.y.3.0/24. dnsmasq does a grand job of issuing a suitable DNS server address with the DHCP option 6. So, machines on subnet x.y.3.0/24 are told that the DNS server is x.y.3.2, machines on subnet x.y.2.0/24 are told that the DNS server is x.y.2.2 and machines on subnet x.y.1.0/24 are told that the DNS server is at x.y.1.2. Even though the DNS server is the same box (although with three nics).
Now the question is:
How do I make dnsmasq respond similarly to name resolution requests? So that when:
Machines from x.y.3.0/24, ping <name of DNS server> dnsmasq returns x.y.3.2,
Machines from x.y.2.0/24, ping <name of DNS server> dnsmasq returns x.y.2.2, and
Machines from x.y.1.0/24, ping <name of DNS server> dnsmasq returns x.y.1.2.
Currently, the DNS server returns the IP address that is assigned in /etc/host. Which, of course can be changed, but via that mechanism, will always be wrong two out of three cases.

how to change the IP range provided by default by Network Manager / dnsmasq from 10.42.43.-- to something else?
I have setup a working network using a Bell wireless modem (Canada) and Network Manager in 8.10, 9.04, and 9.10.to do Internet connection sharing. In 8.10 the only way I could get it to work was with WICD and KPPP, many hours spent on this one. I got it to work in 9.04 and 9.10 using network manager, but certainly not out-of-the-box. If someone would like some tips on how I did it, in each case, let me know.
My current challenge is trying to set the dhcp range of dnsmasq (which I am 99% sure is what is handing out addresses) from th 10.42.43.-- address range to a 192.168.0.-- range.
I HAVE edited /etc/dnsmasq.conf and can get the edits to this file to break the setup (dnsmasq will not start) but have not been able to get it to change the IP address range.
It seems that either this file is ignored, or overridden by some other process. I have looked at the very good post at [URL] about dnsmasq but this does not do the trick.
By the way, the way I can get this to work is to start NM, establish my cellular internet connection, then kill dnsmasq then establish my ICS network (on eth0). If I don't kill dnsmasq, then it does bring up the connection, but it then shuts down in a matter of seconds. It is all very manageable using a launcher (kdesudo pkill dnsmasq) on the task bar, but not all that elegant.
the IP range and where this is provided to Network Manager or the network itself is my real question now.

I would like to update my network setup.
Today, I have an ADSL box which is my gateway to internet (192.168.0.1).
I have a Raspberry pi (RPI) which I use as a dhcp & dns server (192.168.0.2).
Recently my mobile phone operator installed a 4G antenna beside my home, and the bandwidth and latency are much better with my mobile phone than with my internet provider (ADSL).
I would like to install a wifi dongle on my RPI (I would get wlan0 & eth0 interfaces)
When RPI detect my shared phone connection (tethering) I would like RPI to automatically route internet:
- from authorized devices on my network to my mobile connexion (wlan0 -> mobile phone).
- from other devices to the standard ADSL internet (eth0 -> ADSL box).
I don't want any device to use the shared 4G connexion, best would be authorized devices to be selected by MAC address. How I should properly setup such a network ?

I would like to setup a Linux Router with Fedora. Here is what I have and would like to do...
Email filter device is on the LAN at 192.168.x.3. I need to provide SNAT to that device from both T1 interfaces...
All outgoing traffic will route through DSL except for traffic destined for addresses on either eth0 or eth1 (web sites).
I assume I would need the following:
I also assume I would need to setup iptables with FORWARDs for the 192.x.x.x networks to eth3.
What I am not sure how to do, is properly setup the incoming redirections so that the email filter can be access from both eth0 and eth1 by different IP addresses.

I have multiple devices in my garage that need internet connectivity. I have my main Netgear router inside the house. I have a computer running Ubuntu in the garage with dual NICs.
Here's a map of how I have it setup now: [URL]
Here's my /etc/network/interfaces:
Code:
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet static
address 192.168.1.60
netmask 255.255.255.0
gateway 192.168.1.1
auto eth1
iface eth1 inet static
address 192.168.1.5
network 192.168.1.0
netmask 255.255.255.0
broadcast 192.168.1.255
I was trying to keep everything on the same subnet. Eth0 is the external NIC, connected to the router in the house. eth1 is the internet NIC, which would go out to the devices in the garage. Now, I know it would be easiest to just connect a switch up and run all the devices in the garage off that switch. But the switch I have is a 10/100, and my network in the house is gigabit, and I want the PC in the garage to have gigabit access... which is why I'm doing this dual NIC setup and using the PC as a router, then the other devices in the garage will be 10/100.
In addition, I used the shell script as described in this article: [URL] to setup iptables. I also uncommented the net.ipv4.ip_forward=1 line in /etc/sysctl.conf. What am I doing wrong here? None of the devices in the garage that I connect up to the Ubuntu PC are getting connectivity. None are getting a DHCP lease from the main router in the house. The Ubuntu PC itself has internet access just fine though.

Here's my setup. I have the modem connected to a switch (wired) that connects 2 PCs to the internet (one desktop, one server, both wired).
All of the threads I see that discuss static IPs seem to require that I set up a router. Is this necessary? Can I still transfer files through a switch?
