How can I add this to Ubuntu so that I can effectively use both networks connected to my machine. All I do in WinXP is run this from the command prompt: route -p add 10.0.0.0 mask 255.0.0.0 10.15.122.9
View 3 RepliesI have 3 network interfaces on my Linux Router :
Interface - Gateway - Type
Code:
br0 - 192.168.0.1 - Internet
eth2 - 192.168.1.1 - LAN
tun0 - 10.0.0.2 - VPN (via br0)
What I'd like to do is to route all TCP packets coming from eth2 to tun0 where a VPN client is running on 10.0.0.2. If I delete all default routes and if I add a new route to tun0 like :
Code:
route del default
route add default gw 10.0.0.2
Everything is fine, and everyone on eth2 can reach the Internet using the VPN access. Now the problem is that my VPN client does not allow any other protocols other than TCP. And I also want to allow VPN access only to eth2, no other LAN nor the router itself. use iptables to filter any TCP packets and mark them, so they can be sent to tun0, while any other packets can reach the Internet via br0 (192.168.0.1). I found on the Internet that we can mark packets before they get routed. Using the following commands :
Code:
iptables -t mangle -A PREROUTING -j MARK --set-mark 85 -i eth2 -p tcp --dport 80
ip route add table 300 default via 10.0.0.2 dev tun0
ip rule add fwmark 0x55 table 300
First of all, --dport 80 never work... :/ I wanted to filter TCP 80 packets coming from eth2, but none of them seems to be HTTP packets... oO (very strange...). Nevermind, I decided to forget about the --dport option. I use the "iptables -L -v -t mangle" command to see how many packets are marked, and it is working fine, all TCP packets coming from eth2 are marked. Now the problem is that none of them are routed to tun0 they are all respecting the "route -n" rules... and not the "table 300" rule I have created.
I would like to add a static route, however I do not understand what is meant by the Address setting below
GATEWAY2=10.241.58.62
NETMASK2=255.255.255.224
ADDRESS2=10.241.57.32
Does this mean any addresses beginning with 10.241.57.32 are routed over the gateway 10.241.58.62 an address range

View 1 Replies View RelatedHaving trouble getting my Netgear WNA1000 working thru wireless router. Have tried lots of suggestions from other threads to no avail. Someone suggested that th routing table isn't set correctly, so have been trying to use the follwing to make the proper entry in the routing table: sudo route add -net 192.168.0.1 netmask 255.255.255.0 dev wlan0
Result: error message stating with:
"route: netmask does not match route address"
followed by "Usage" instructions which tell me to do what I just did. Any ideas on how I can populate my routing table with correct entry for my wireless card? Not to complicate matters, but I temporarily turned off encryption on my router to eliminate that as a possibility until I get connected. So maybe it'still trying to connect via encrypted mode - do I need to turn off encryption on my (client) end?
I got this definition:"a process that replaces a series of related, specific routes in a route table with a more generic route." honestly I found it not so clear.. I want to know if this definition is correct and also more details about this subject..
View 1 Replies View RelatedI have a linux desktop with two connections - fast eth0 and slow modem ppp0. Most of traffic (e-mail, DNS, NTP) can be routed simply by IP/mask. But how about http and p2p (torrents, DC++)? Routing by IP is unacceptable, because there is very huge amount of routing rules. I need route http packets (80 port) through ppp0, p2p through eth0 (10000:65535 ports). I've found that splitting traffic by port is possible with marking packets for different gateways. For begin I cleared all tables and bringed up connections.
Code:
# iptables -F -t mangle
# iptables -F -t filter
# iptables -L -t filter

I am using ubuntu Lucid and connected to a network with windows machines.Our network admin changed some settings in the network, and all machines need to change their subnet masks to access local machines (e.g. I am getting "unable to mount" message when I try to connect other Windows PC's on the network.)
If I open the connections panel, and "Edit" the "Auto eth0", I can get: IPv4 Settings -> Method -> Manual -> Addresses -> Add .And I am pretty sure I will put new subnet mask address into "Netmask" box, what to put others? Namely:
IP Address, Netmask, Gateway and below:
DNS Servers, Search Domains
I can get some info about my network connection by right clicking network icon on the panel, and select "Connection Information" Tried to fill manual settings with some of those info (the ones made some sense to me) but I still cannot mount windows network drives, plus my internet connection dies.So, is there any way to change Subnet Mask "ONLY", without touching any other setting.

I have 3 computers on a local home network. Computer 1 is not receiving incoming anything from other computers on the network, and I don't know why. The regular internet works fine. Computer 1 can ping and ssh into either 2 or 3. 2 can ping and ssh into 3 and vice versa. But nothing can ping OR ssh into 1. Trying to do so says "no route to host". All computers are running Ubuntu Karmic. I don't even know where to start figuring out what's causing this, but it's probably something simple. I'm using the IPs I found listed in my wireless router's web-based control panel.
View 9 Replies View RelatedI have a 10.04 install with 2 network cards. wlan0, and eth0. wlan0 is the internet connection. eth0 is the local network. I want to be able to have internet connection sharing between eth0 and wlan0. I have set everything up, using firestarter.
is there a way of testing the eth0->wlan0 routing from the machine itself? The routing table looks sound, but I would like a quick way of confirming it. Is there a tool, like PING or TRACEROUTE which will let me say "ping [URL] going through eth0" ?
I set up a routed OpenVPN server. Everything works fine. But I'd like to route the DNS queries thru the tunnel too. So I added:
[Code]....
Can't find server name for address 10.8.0.1: Non-existent domain Even thou I have a DNS server set up correctly (on the same server as the VPN) with recursion. I verified that by sending queries form external source, which worked fine. I suspect that the Bind server doesn't listen to the tun0-interface only eth0, but the Bind manual says it should listen to all interfaces by default. The server log shows:
Code:
named[9639]: client 10.8.0.10#3807: RFC 1918 response from Internet for 1.0.8.10.in-addr.arpa
How do I get these DNS queries to resolve thru the tunnel?

View 2 Replies View RelatedI am running 10.04 and am trying to add a route to a remote network using a gateway that is NOT on the local subnet. I am not messing with the default GW as all the other posts I can find are. I am using public IP addresses, but all of this is contained behind a firewall. I need to add a route to a private network (192.168.1.x) that is behind a router attached to a different subnet. The current routing table looks like this:
Code:
Destination Gateway Genmask Flags Metric Ref Use Iface
xxx.xxx.108.48 0.0.0.0 255.255.255.240 U 1 0 0 eth0
0.0.0.0 xxx.xxx.108.49 0.0.0.0 UG 0 0 0 eth0
The remote network is 192.168.1.0/24 and it is reachable via xxx.xxx.37.203. I can ping the gateway no problem. However when I try to add a route to this network I get an error.
route add -net 192.168.1.0 netmask 255.255.255.0 gw xxx.xxx.37.203
SIOCADDRT: No such process
I assume this is because the GW is not on the local subnet. When I try this on a machine that is connected to the xxx.xxx.37 network, everything works fine and I can reach the remote network. I even tried adding a static route to the gateway, but that did not help.
route add -host xxx.xxx.37.203 gw xxx.xxx.108.49
I'm running Linux Mint 10 . I have a wireless PCMCIA card (Linksys WPC 11 ver.3) that I've put into master mode, and I'm trying to set up my laptop as a wireless hotspot. I am very confident that I want to do this and have no interest in using a wireless router....I say that because that topic inevitably comes up with posts like this. The problem I'm having is I don't understand how to get wlan0 and eth0 to "talk" to each other...That is, I don't know how to set it up so that traffic from wlan0 goes through eth0, so that devices that connect to my hotspot can access the internet.I've seen a few guides about this, but they were either much broader in scope (i.e. much more complex), or for other distributions, etc, and it's too much for me to follow as a linux .

I can assure no one is working at the server or doing anything over there.Does anyone know causes that might be triggering route default to stop working?Btw where is the best place to add this command so it will be executed automatically on start-up and without needing to login to the server?

I have two NIC's interfaces on my linux machine(eth1 and eth2). Each have different IP addresses(10.0.0.1, 10.67.7.1). These two interfaces are connected together through hub. Here is the my question?
1) If I 'ping 10.0.0.1', it should go out through network interface eth2 and through hub and enter on eth1 and response also travel through similar direction.
2) If I 'ping 10.67.7.1', it should go out through network interface eth1 and through hub and enter on eth2.

I have some CISCO,Linux related problem with 2 Class C subnets:
192.168.64.0 -> PC5
192.168.65.0 -> PC6
Here's a picture of my situation: [URL]
HQ has to have 2 STATIC routes in order those 2 "PCs" mentioned above to have end to end connectivity with NETWORK A and NETWORK B. Now I try with
route0 -> network: 0.0.0.0, mask: 0.0.0.0, nexthop: Serial 0/0/0
route1 -> network: 0.0.0.0, mask: 0.0.0.0, nexthop: Serial 0/0/1
And it seems to work but I don't think it's proper! I feel it's kinda wrong ... but all my other attempts to set another couple of static routes ends in "Request timed out" and thus connection lost.
I'm trying to troubleshoot some networking issues I'm having between my Linux servers connecting to a server at another location after a Cisco ASA firewall has been installed at my location. I can make the connection work if I lower the mtu on the NIC (ifconfig eth0 mth 1000) - however that supposedly can break the local network if I don't set everything else's mtu to match. Supposedly I can use the iproute package (debian etch) to lower the mtu on a per-route basis, but it doesn't seem to work for me.
Code:
ip route delete default
ip route add default via X.X.X.X mtu 1000
I have a server that I can ping, and I can connect remotely with ssh to it. But when I try to connect to apache (port 80) I get "no route to host".

I have an Asterisk-server with 2 interfaces, a WAN-interface (eth1) and a LAN-interface (eth0).
SETUP : IAX-provider(internet) --> firewall --> Asterisk-server --> switch --> clients_on_LAN
So everything coming from the IAX-provider on port 4569 is forwarded to the Asterisk-server's WAN-interface (eth1). This needs then be routed to an internal SIP-phone (an IVR-system will define which one) via eth0. When a call is initiated from an internal SIP-phone (they register to the IP-address assigned to eth0) it needs to be routed via eth1 to the gateway (192.168.4.250). Asterisk will setup an IAX-channel on WAN-interface (eth1) to the IAX-provider (via gateway). So... will this work :
Code:
route add -net ip_IAXprovider netmask 255.255.255.0 gw 192.168.4.250 dev eth1
Code:
route add -net 192.168.4.0 netmask 255.255.255.0 dev eth0 (no gateway needed for the LAN-interface, communications to the gateway need to go via the WAN-interface !)
We have a Red Hat Linux server that sends email out daily. It points to and Exchange server for smtp. It works fine, however, at least once a day, an email will fail and in the maillog I see "No route to host". After a few minutes, everything is working fine. The Linux server and Exchange are on the same VLAN and IP subnet.
