Network Bridge betw/ eth0 and wlan0

English Network/Internet

Good evening, OpenSUSE users.

I’m new to this forum site and I was wondering how can I bridge a network between the eth0 and wlan0 connections?

my eth0 NIC is a RealTek RTL8111B 10/100/1000 Ethernet Card (OnBoard) and my wlan0 NIC is a RealTek RTL8187B 802.11b/g WiFi USB Adapter Card.

Are there any utilities, such as bridge-utils that I can use, except for Firestarter since Firestarter states that the eth0 connection is not established, or do I right-click on the network icon and select Edit Connections and go to Auto eth0 and under the IPv4 Address setting and select Shared to other computers and run a live connection there?

The main reason is that I need an Internet connection for my Xbox 360, which is connected to my Linksys WRT54G 802.11b/g Wireless Router, that has DD-WRT firmware installed and 4 WiFi hotspots for any wireless device, such as my PSP, DS, DS Lite, Wii, Laptop(s), my brother’s PC (needs a WiFi card), and my dad’s PC (needs either a WiFi card or an Internet connection from my brother’s computer to my dad’s PC)

Here are my Computer Specs:
ECS nForce6m-a Motherboard
2GB DDR-800 PC6400 Memory
WDC WD135BA 13.5GB IDE HDD*
Seagate ST310005 1TB SATA HDD**

Corsair HW520W PSU
AMD Athlon X2 64 Dual-Core Processor 4000+ 2.11GHz per core (4.22GHz total)

Things connected to my Ethernet port on my PC:
Linksys Workstation 5-port switch (Port 5 (uplink): PC, Port 1: Wireless Router)
Linksys WRT54G Wireless Router (WAN: Switch, LAN: Xbox 360, WLAN: PSP, DS, DS Lite, other PCs)

thanks for helping you guys, Merry Christmas, and a Happy New Year. If you’re wondering why I have a lot of things in/connected to my PC, basically, some of the parts were on sale.

I’ve done it a long time in the past and as far as I can remember the only thing that’s needed is NetworkManager and dnsmasq package. Try this procedure and see if that works.
How to share a wireless connection with others using Ethernet and Fedora - Fishpool
I did this quite similar to what is written there however I was using gnome at that time and a NetworkManager client with a bit different interface that what is available today.

Best regards,

Hello,
I’m confused: how is your computer connected to the internet in that scenario?

4

The computer is connected with wireless to the router and the Xbox is connected to the router through ethernet card of the computer.

5

and the router connects to the internet? So the xbox should be already connected to the internet. Why do you need to “bridge” eth0 and wlan0?

Oh wait sorry, I just read that again.
but earlier you said

And I was having trouble working that out.

NAT may do what you need as well:
