Hi, my company have just bought new network and I have question about one problem. As in topic we must use few completely different dsl''s and balance traffic between them. 2M/0,5M 4Mb/0,5M 8M/0,5M M=Mb/s I''ve never done such thing before so I have doubts how it will work. If the links are symmetric 2/2 4/4 8/8 there is no problem because with weights I can compensate the

Hey guys, I have a question regarding shorewall and vrf functionality. I have shorewall 3.4.8 and kernel 2.6.24-gentoo-r8 I have tried to use iproute2 (ip route and ip rule) to establish multiple routing tables. The biggest problem seems to be, that I cannot add interfaces such as vlan interfaces to the routing table. My target is that linux takes attention of on which vlan interface

I''m playing around with VLAN''s and I have a VLAN capable (layer 2) smart switch. I see a steady stream of martians in the logfile if I have the routefilter option set on the loc zone interfaces in /etc/shorewall/interfaces. I have two interfaces in the loc zone, eth1 and vlan2 respectively. vlan2 is an 802.1q trunk going towards the switch. Is this the expected behavior in

I have a computer with two interfaces, say with addresses 192.168.1.1 and 192.168.1.2. I want to set up routing such that when I ping 192.168.1.1 it goes out through 192.168.1.2 and not to the local interface. Is this possible - all my attempts so far have been unsuccessful? If so, pointers, etc. would be gratefully appreciated. Jim -- Jim Redman (505) 662 5156 x85

Can I add routes to rt_tables by hand with the vi editor? If I add a route to that file, it will be there if I reboot the box? I am sure there are stupid questions but I can''t find the answer into the papers I have here. Luis Miguel Cruz Miranda.

I have a 2.6.12(ubuntu-patchset), kernel recompiled with this routing options: [*] IP: advanced router [*] IP: policy routing [*] IP: equal cost multipath Load balancing is working great, but i have problems whits long term tcp flows (like msn-messenger or vpns or any other type of long term ip based conection). I assume this is because after a period of time, the per-host

I have a setup with two Internet providers. One circuit (net0 == eth1) is used primarily for employees and tunnels to other sites. The other (net1 == eth2) is for the production machines that customers access. Everythung works in teh sense that packets get to where they are sent (mostly) but I recently I had a sniffer on the system and noticed a problem I cannot solve. traffic coming in

Hi, i have a question if linux is able to do the same thing that commercial wan simulators do (which cost 7000 $ or more). Basicly i want to use the following setup. Linux Router Machine 192.168.0.1 192.168.1.1 Eth0 192.168.10.1 Eth5 192.168.2.1 Eth1 192.168.100.1 WEB Server. 192.168.3.1 Eth2

Hello newsgroup, I hope somebody with more routing experience then me can help me with the problem I have. The setup is as described below. A dual internet provider routing, multiple local area networks, and a dmz network with one public and one private ip range. I followed the instructions at lartc.org, and so far everything is working. The default route is via

I couldn''t find anyone who had actually made it work via google so I guess I''ll ask here. My setup is a VPN point to point link. The VPN is a modified version of Openvpn where I''m using zlib compression to improve the compression a bit. The goal is to shape traffic coming from a routing server through the vpn to the endpoint of the vpn and in such a way maximize the

Here is a portion of the script (the whole script shapes several

I'm looking for some information regarding the interaction of KVM, VLANs, firewalld, and the kernel's forwarding configuration. I would appreciate input especially from anyone already running a similar configuration in production. In short, I'm trying to figure out if a current configuration is inadvertently opening up traffic across network segments. On earlier versions of CentOS
