Letting linux be the router, allowing dynamic routes, suggestion
I see what you want me to do. But it does incur an extra MAC layer header
to each VPN packet, more fragmentation.
And broadcasts leak to all peers.
It sure saves you from doing any improvements, but there are side effects
that are undesirable to many customers.
This is specially a problem if I want two VPN connections between two sites
using redundant connections, we get an instant L2 loop.

routing within the same network? is it possible?
Hello,
Is routing within the same network possible?
If it is, what configuration should I put for the firewall/router shown below? I basically want the host debian13 to be able to send packets via a multi-homed firewall. I think the multi-homed firewall involve some routing.

No, this would in fact operate as a routing mode instead of bridging.
TAP would be used as a means to push routing to where it belongs, the
linux/bsd/... kernel.
Consider the challenge of having completely dynamic routing between vpn
peers. In one minute I might have 10000 routes towards one specific peer,
and hour latter I might have NONE. And I need to diferentiate each peer at

What challenge this would solve ?
VPN software in general tries to be another router when running in server
mode with multiple clients.
This restricts VPN customers from having complex topology.
For instance, I'd like to have two tunnels between each client network and
each server (with two broadband connections on each end), with some OSPF
running and automatically switching from one to

ARP limit ?
what is the limit on the arp cache entires ?!
Does someone have very big LANs with linux-routers ? How big ? (i mean flat L2 network, not segmented)
I want to know how much can my net can scale ?
thanx

packet in the kernel
Hi all,
Can someone say me the theoretic way of packet in the kernel.
When the packet will be send to a IMQ device?
When the packet arrives to post routing time?
When operation of NAT occur? befor or later that the packet will send to net
device?
Thanks
Bye

[Bridge] Ubuntu: network bridging between wireless and wired connection fails
Hi everybody,
First of all, let me say that I searched a lot on the internet. I
spent several hours sitting after my notebook, but I can't configure
my network bridge in Ubuntu. I'm really desperate, so I hope somebody
can point me out what I'm doing

equal-cost multipath in 2.6.7
I have question about multipath routing. I am running a 2.6.7 kernel (gentoo).
I have a route with three nexthops on the same interface. I see a
different nexthop being picked for different destination addresses.
All is fine.
Now if one of the nexthop goes down (arp entry times out and arp
request doesnt get a response), does it remove the nexthop from
contention and only use the remaining two

Complex Routing/Firewalling/Bridging question
I''m being cast headlong into unfamiliar waters here, and being desperate for
some air, thought I''d come here for some help. :)
Anyway, my employer is going through some whiplash-inducing growth spurts,
and as a result, the simple "Internet T-1 -> Linux Firewall/NAT -> LAN"

Linux bridging and cascaded switches
Hi -
Still plugging away at my Linux bridge/firewall and thinking through the
consequences. In a normal firewall situation, the Internet is on one
side, the internal LAN on the other. Duh! But now, with a Linux bridge
in the middle, the whole thing becomes one big messy LAN. So we have a
scenario that looks like this:
Internal---User---Core-----Firewall---Internet---Internet router

Routing NDAS ?
Hi,
I believe ndas devices (http://www.ximeta.com/web/technology/) use raw
Ethernet frames, as they require no tcp/ip configuration, the client
finds and authenticates with a code that is different for each device
sold, like a network mac address.
My pc is on a different segment to the ndas devices that we have, the
two segments are linked by a linux box that is doing routing and proxy

East-west traffic network filter
Hello,
I would like to make filter that allows communication only between
specified VMs. Those VMs should be specified by their MAC address. The
filter should extend clean-traffic but I was not able to get it working
with that reference. I have came up with modified clean-traffic which works
fine [1]. Is there a way to achieve the same behavior with reference to
clean-traffic?
Thank you.

Virtual Routers would this work?
Hello all,
I need a virtual firewall/router solution. I''m thinking of a
netscreen 1000 but I want to know if it can be done in Linux.
Here is my idea:
1 Linux box
2 GigE interfaces
1 interface setup with a public IP address ($PUBIP)
1 interface setup with 802.1q VLAN trunking with 100 vlans assigned
($VLAN1-$VLAN100)
a /25 subnet routed to $PUBIP from my core routers
All $VLAN

policy routing at its best
hello list (and martin) ;x
i have now composed my final(?) policy routing design.
the goals i had when beginning with this, for you that have not follow
mine and martins thread, was to 1) only let 192.168.1/24 to see all routes,
2) not route between defined networks, except to and from 192.168.1/24 and 3) not
defined networks should only be able to reach 192.168.1/24.
this might sound simple.

Shamelessly reusing the announcement Arnaud sent about three months ago
for nut-2.2.1:
"We're preparing to release 2.2.1-pre2, so if you have some fixes to
backport on Testing, consider announcing it and doing asap.
As always, compatibilities update and bugfixes only!"

Hardware Configuration Ideas
Hey guys,
I am planning to buy some components for a Linux router that will handle the
Internet access of 200 computers (includes tc shaping) and some inter
sub-network routing (at least 100MBps per eth - and there are 3 eth cards).
I was thinking of a:
Pentium 4 - 3GHz
256 or 512MB RAM
Network Cards.
Now - I wonder what is more important: the processor speed or the amount of
RAM.
