Hello, I'm trying to set up port forwarding in IPTABLES and so far it's working great from the internet, but when I attempt from my internal LAN using the External IP address, it fails. EXTIF="eth0" INTIF="eth1" EXTIP="xxx.xxx.xxx.xxx" INTNET="192.168.1.0/24" INTIP="192.168.1.1" PORTFWIP="192.168.1.13" >From the internet,

Hello * community, I have 2 * boxes spanning a t1 with hdlc. I'm trying to route packets so people on a subnet seperate of the * boxes can browse the boxes on the * spanned subnet. The * boxes and the boxes on subnet controlled by * can see everything. The boxes on the seperate subnet inside the company can only see so far as the first * box and can't ping across the span.

Hi there. I have followed some documents found here and there, but do not have already success implementing a script using iptables and iproute. What I need is to send all traffic trough an ADSL line, but mail trough an expensive and slow DS0. The mail server lies on the PC acting also as firewall. I include the script. When using that I get some error messages (I found that the flush command

Hello, I have a webcam that I wish to view from the internet. It is a wireless linksys model with an ip address of 192.168.1.15. I have it set on port 8081, 192.168.1.15:8081. I am using the IP Masquerade HowTo script. Here's the rule I added to my firewall script: EXTIF="ppp0" INTIF="eth1" EXTIP="`$IFCONFIG $EXTIF | grep inet | cut -d : -f 2 | cut -d \ -f

I am using the madwifi driver with the patch to allow changing of the MAC address and I have two other ethernet interfaces plus a pppoe interface. My outbound connection is ppp0. I have ath0, eth1, eth2 for internal interfaces. I have added these three interfaces to br0. Once the traffic leaves the linux router, it gets NAT'd and goes out through ppp0. All traffic on all segments works

Hi, I am trying to have some routing done between two subnets. One is 192.168.1.0/24 and has my LAN computers running a mix of Windows 98/XP clients. There are two linux machines on this network running Samba. Another is 192.168.0.0/24 and has the other LAN. Only my linux machines have two NICs, one for each LAN. I am trying out one of these linux machines to be the gateway for both the

Yesterday I posted a question, but I guess too much detail is provided that no one would bother to read, so I rephrase the question and hopefully some one may be willing to read. Sorry to spam. I am using TEQL on two computers, each with two network interfaces. The two eth0 are connected directly, and the two eth1 are connected via a gateway (a linux machine). The problem is that when I send

Hi there, I have two ethernet connections of 2Mbit/s each and I''m trying to add them together to one 4Mbit/s connection but I cannot get more than approximate 1Mbit/s! My setup: I have a LAN (10.2.18.0/24), connected to a larger network (10.0.0.0/8) by two WAN-connections with 2Mbit/s each. On each end I have a Linux router. I first setup the routers to use TEQL with one of the

OK, I spammed the mailing list recently, but I will be fired if I can''t solve the problem today. (just kidding, but I did waste lots of time on it :( ) The common configuration for teql is for two computers connected directly with two links. My topology is a little different: one link is connected directly, but the other is connected through a gateway. My problem is teql can''t

TEQL and Subnet problem I have a network topology shown below, and I am trying to use TEQL. My problem is: When I ping to P3.teql0 from P2 ("[P2]# ping 16.119.144.66"), the traffic can never go from P2.eth1, and all traffic only goes to P1.eth0. What P2.eth1 (16.119.144.33) did is broadcasting an ARP asking for the MAC address of 16.119.144.66, although I have specified the route to

Easy question here: I have a test network that looks like this (apologies for my lack of ascii skills): [hostc]---------------[Firewall]192.168.42.1 (EXTIF: eth0) /10.0.0.1 (INTIF: eth1) 192.168.42.10 (wan) |(lan) | +-------------[hosta] 10.0.0.10 (port 4242) | +-------------[hostb]

Hi all, I need a little help, i am studing htb to control user bandwidth (download/upload) and I made a script as below to test. I am testing using ttcp tool from by linux box to other linux (192.168.200.51). my box <---- Linux = more than 128kbit mybot -----> Linux = get 128kbit But I want to control both ways, what am I missing? script: EXTIF=eth0 INTIF=eth1 TC=/sbin/tc DOWN=128

Hi, this is a followup to "Problem with HTB and ceil", the problem with the ceiling has been resolved, thanks to the memebers on this m/g. Now I have the problem that packets get into the correct classe with the correct marks but the prios are not respected. I have 4 different classes: 1. voip class / prio 0 / mark 100 / voip traffic 2. ACK class / prio 1 / mark 200 / ACK packets to

Thanks in advance! Summary: when I load netem and teql together, teql doesn''t work correctly. (If I load teql only, everything is fine) I loaded both netem and teql. Netem is associated with eth0, and teql is associated with both eth0 and eth1. But traffic only goes out of eth1. Attached are the commands that I used to configure teql and netem (on machine 1), and commands to

Hello, After reading the excellent HOWTO I got traffic shaping working nicely over ethernet devices on a test setup. I can''t put this setup live though, because our main firewall has three 2mbit hdlc interfaces instead of a single device. We are using multipath routing using iproute2 nexthop at the moment, and that works fine for firewalling. But now I have a need for shaping and

Dear List, Another noob question today! I''ve been using iproute2 for a long time now to manage bandwidth and directing traffic over multiple interfaces based on source routing. I am working on a test-project at the moment, in witch I want to actually bundle (''trunk'') some connections. In the LARTC-manual I found the chapter about TEQL (see chapter 10). The situation

Sorry this is the right message. Hi all, in my school I have: - two Netopia router for ADSL (perform NAT), - one linux box with 3 ethernet card I want to make a load balancing on the two ADSL line. I have configured the system as follow: The LAN interface, of the two ADSL router, have address (A) 192.168.0.254 (B) 192.168.2.254 The 3 ethernet card, on the linux box, have address: -eth2

I suppose a few questions pop up on this list about access Samba through a firewall. ?I have been very successful running Samba through a firewall, until today. ?I hit a stumbling block. I have a Linux Firewall with the public IP Address of 134.x.x.140 <it is not the exact ip address, but close>. ?I am using NAT and port forwarding to send traffic destined for 137, 138,139, and 445 for BOTH
