Ok, I just figured out what's going on.. The network 192.168.1.0 doesn't
have a route to known the hosts in the network 192.168.5.0. <br><br>Is it possible to NAT all the lxc network to route to the 192.168.1.0? <br><br><div class="gmail_quote">2013/7/25 Luis M.

<p>Hello Luis,<br>
Your host routing table specifically identifies the DGW as 192.168.5.1 (the last line)</p>
<p>why would you think you could "go anywhere" without a DGW?</p>

Hi everybody,<br><br>I run over this issue. I have an lxc host with this routing table:<br><br>#route -n<br>Kernel IP routing table<br>Destination Gateway Genmask Flags Metric Ref Use Iface<br>192.168.5.0 0.0.0.0 255.255.255.0 U 0 0 0 br0<br>
192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0 eth1<br>0.0.0.0 192.168.5.1 0.0.0.0 UG 0 0 0 br0<br><br>and <br>#cat /proc/sys/net/ipv4/ip_forward <br>1<br><br><br clear="all">
and an lxc guest with:<br># route -n<br>Kernel IP routing table<br>Destination Gateway Genmask Flags Metric Ref Use Iface<br>192.168.5.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0<br>
169.254.0.0 0.0.0.0 255.255.0.0 U 1002 0 0 eth0<br>0.0.0.0 192.168.5.154 0.0.0.0 UG 0 0 0 eth0<br><br>with this configuration packets can't go anywhere. If I change the default gw of the lxc guest to 192.158.5.1 at least I get all the network 192.158.5.0.<br>
<br>My question, why am I missing to get this working? <br><br><br><br><br>-- <br>Luis M. Ibarra
