Recommendation for PCI or PCIe NIC card

Does anyone have a recommendation for a good 2 port PCI or PCIx (x2 or x4) Ethernet card for bridging?

Intel e1000 PCI-X and PCI-e nics perform very nicely for me..I've found
nothing faster.  You can get 2 and 4 ports all over, and can get 6 port
nics from silicom-usa.com.

Bridge not working for 2.4.21 kernel

Hello All,

 

Hope someone will address my problem.

I configured my Linux box (2.4.21 kernel) with the ebtables-brnf-10_vs_2.4.21 patch.

I had installed the bridge-utils package also.

As soon as the I type the following commands, it hangs

#ifconfig eth0 0.0.0.0

#ifconfig eth1 0.0.0.0

#brctl addbr br0

#brctl addif br0 eth0

#brctl addif br0 eth1

#ifconfig br0 up

 

The following scenario explains my setup:

 

Thank in advance.

Any help will be highly appreciated.

 

 

Regards,

Suraj

Re: Bridge not working for 2.4.21 kernel

Your switch will forward traffic from N/W1 to N/W 2 without going through your linux bridge. You should use two seperate switches and bridge them with your linux box, or segment the switch with VLANs and forward between them with your linux box.

Help: Bridge and NAT through same NIC?

I am so out of my depth on this one, but I would welcome some help.  I
have the following network and did get it to work with m0n0wall (a BSD
firewall) an option called "transparent bridge".  I've switched to Clark
Connect because of its support for content filtering, and installed
bridge-utils.

I have a home network based a single WAN-facing NIC, eth0, that gets a
public IP address from DHCP and two internal NICs:
	- eth1: that provides simple NAT for several PCs
	- eth2: a cable set-top-box that needs an IP address from a specific,
and separate, DHCP server (that checks MAC addresses so that only STBs
can connect to it).

The diagram summarises:

Internet --- DHCP server ------ eth0 ------- eth1 ---- Home network
              (public IP)     |            |
                              |            |
TV-content --DHCP (server) ---            -- eth2 ---- TV set-top box
              (Private IP)

I tried to set up a bridge of eth0 and eth2 using:
ifconfig eth0 0.0.0.0
ifconfig eth2 0.0.0.0
brctl addbr mybridge
brctl addif mybridge eth2
brctl addif mybridge eth0
ifconfig mybridge up

But that did not enable my STB to connect and meanwhile I had of course
lost connectivity for the PCs.

bridge wont forward when ip address changes

hello :)

I have been using the bridge utils for a long time now and its been very
good but there are a couple of issues that I came across when trying to
setup a wireless bridge...

Firstly I currently have a setup like the following ...

Computer A --- Wired Network --- linux box ---- wireless link ------
linux box ----- Wired Network --- Computer B

I have bridged the wireless interfaces and the wired interfaces together
on both of the linux box's and data can travel across the wireless
bridge without any trouble but if I attempt to change the IP addresses /
subnet of Computers A and B the bridges seem to stop forwarding packets
and no data get through at all, its like they aren't learning the new
addresses.

If I restart the 2 Linux boxes then everything starts flowing properly
again.

The 'Linux boxes' are a couple of Motorola Wireless Access points
running OpenWRT.

Does anybody know why this might be happening and what I might be able
to do about it?

The other issue is that the this bridge setup doesn't seem to forward
any NetBIOS traffic, however, i'm not too worried about this its more of
just bring curious.

Thanks for your help,

Matty.
