[Lxc-users] Running LXC containers on a laptop

2010-09-24 Thread matto fransen
Hi, When I use br0 on my laptop (with wifi connection) I can connect from the container to the laptop, but not outside the laptop. What is the most easy way to setup wlan0 as gateway for the containers? Thanx! Matto

Hi, you need to setup snat or masquerading if you want your containers to access the network. # sysctl -w net.ipv4.ip_forward=1 snat (you need your ): # iptables -t nat -A POSTROUTING -o wlan0 -j SNAT --to-source=WLAN0_IP OR masquerading: # iptables -t nat -A POSTROUTING -o wlan0 -j

I'm lazy too, that's why I let libvirt set up and maintain networking for me. apt-get install libvirt Now, set up your guests with: lxc.network.type=veth lxc.network.link=virbr0 lxc.network.flags=up and NATing should just work. FWIW. - Scott

I never tried libvirt (I guess all this XML scares me a bit:-P). Are there any good examples of how to use it with lxc? On Fri, Sep 24, 2010 at 17:38, Scott Bronson bron...@rinspin.com wrote: I'm lazy too, that's why I let libvirt set up and maintain networking for me. apt-get install libvirt
