similar to: How to use different path for INCOME and OUTGOING package ?

Hello, I''m following this HOWTO http://linux-ip.net/html/adv-multi-internet.html to route outgoing SSH from a secondary ISP. I can see using tcpdump,jnettop,iftop that when one of the computers located in my internal network is trying to SSH to a box online using SSH, packets are routed via the secondary internet ethernet card. However, packets don''t seem to know how to get back.

Hi everybody, sorry for posting again, however I''ve moved the problem now ;-) After digging a bit deeper, I''ve successfully set up the routing as such, it works for incoming as well as outgoing packets that take the default route. Changing some of the routes using IP works as well. When I mark some outgoing packets in order to send them via another route (the fast leased line

Can anyone tell me whether I have a routing problem, or an openVPN problem, or something else? I''ve stared at this for so long I think I must be looking in the wrong place! I have 3 machines: Machine A has single ethernet card, eth0, 192.168.5.5 Machine B has eth0, 192.168.5.? on the local net, eth1, 81.2.x.y to the internet, and

Woops - my fat fingers hit the send key before I could put in a subject a minute ago. Hello - I am using kernel 2.4.27 and running into behavior I don''t know how to explain. I have 2 relevant interfaces. eth0 is external, eth1 is internal. My internal LAN is 10.10.10.0/24. My External range is 1.2.3.0/27 (dummied up). I have an H.323 videoconference device inside my internal

HI folks, I have a linux router connected to two separate internet connection from an ISP. There is a third interface ( ip -> 192.168.1.1 ) in the router connected to the local network. Configured the routing tables and added the rules and everything seems to be working fine from the routing box. Traceroute to external internet sites reveal that traffic is being routed correctly and

Hello, LARTC mailing readers, I hope u can help with this mysterious issue i''m having with my linux box acting as a router. Scenario: Linux running 2.6.8.1 /w julians patches /w support for multipath routing Latest iproute (iproute2-ss040702) 4 NICS ----------------- | x eth0 (63.43.x.x) network mask (255.255.240.0) | |

Hi all, I''m trying to set up a computer with 2 routes to the internet, much as described at http://lartc.org/howto/lartc.rpdb.multiple-links.html .One of my interfaces (eth5, 192.168.2.2) is only used for traffic originating inside the network. The other (eth1, 192.168.1.2) is only used for a VPN, where all (udp) traffic originates from outside our network. I have created a second

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

Hello! Problem: Outbound data goes through default interface instead of specified, causing congestion. Question: How can I instruct samba to tell Solaris to SEND data through specified network interface? Detailed: I have a solaris filesserver with two network interfaces, hme0 and hme1. I'd like NFS to use hme0 and smb hme1. I intsruct samba to only listen for connections on the

Hi, I have three linux machines, and I want to let one of them forward packets betwen the other two. The forwarding node has two ethernet cards, connecting the two two machines respectively. However, when I ping between the two end points, the forwarding node can receive the ping requests at its eth0, but it never forwards them to its eth1. So is the reverse direction. The forwarding node is

Hi! I am trying to use hping to chek the latency of our network. Somehow things are not going to plan and I thought someone might be able to shed some light on the subject. Here is the setup: (the IP addresses gvien here are fake, but they do represent the correct state of the networking setup) vlan interface IP mask V2 eth0 192.168.20.20 32

I''m trying to setup some DNAT and the packets seem to be disappearing after the PREROUTING step. The packets are coming in eth2 (both LOG targets in iptables and tcpdump confirm this). They are then DNATed to an IP that should cause them to go out eth3. However I never see them go out that interface. I have tried putting LOG rules into the FORWARD chain with no success. I''m

Hi list! I have a problem where SIP packets sent by Asterisk do not hit the wire, and I don't know what could cause this. I'm running Asterisk 1.8.28_cert5 with full SIP debug. At the same time, I'm doing a tcpdump of the traffic on the network interface. I can see in the SIP debug log that asterisk is sending packets. Most of the time, I can see those packets in the tcpdump,

Hi Roel Just guessing: do you have conntrack enabled? If not, "modprobe nf_conntrack_netlink" (you can remove it and its dependencies later) What are the outputs of sysctl net.netfilter.nf_conntrack_count and sysctl net.netfilter.nf_conntrack_max when the problem shows up? cheers Ethy On Thu, 31 Mar 2016 12:17:12 +0000 "Dovid Bender" <dovid at telecurve.com>

Hi, I have two connections to the Internet. I implemented the load balancing as described in chapter 4.2 "Routing for multiple uplinks/providers" The problem that occurred is that the client applications like Yahoo Messenger or even PuTTY (SSH client) are loosing the connection very often. Does anyone experienced this problem? Does anyone knows an workaround for this problem?

Hi, I am using Asterisk with various brands and models of SIP phones. Especially the Welltech phones LP201 are particularly nasty with volume and echo. Even with the input gain (microphone) of the Welltech set to the max, the PSTN end can hardly hear the SIP user on incoming calls. Ztmonitor also only gives a level of around 3 === from the SIP phone. I have to increase the rxgain and txgain
