I have a virtualbox guest CentOS 8 as lxc host (lxc version 3.0.4) . I’ve created a debian container. But has some issues:
- The container cannot get ip address using dhclient
- The container cannot reach internet using fixed address, however the host can reach the container.
LXC configuration is as follows:
# cat /etc/lxc/default.conf lxc.net.0.type = veth lxc.net.0.link = lxcbr0 lxc.net.0.flags = up lxc.net.0.hwaddr = 00:16:3e:xx:xx:xx egrep -v '^$|^#' /etc/sysconfig/lxc LXC_AUTO="true" BOOTGROUPS="onboot," SHUTDOWNDELAY=5 OPTIONS= STOPOPTS="-a -A -s" USE_LXC_BRIDGE="true" # overridden in lxc-net [ ! -f /etc/sysconfig/lxc-net ] || . /etc/sysconfig/lxc-net
CentOS has selinux disabled and no iptables rules…
tcpdump output in Centos 8:
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on vethY4R8WQ, link-type EN10MB (Ethernet), capture size 262144 bytes 11:05:17.527975 IP 10.0.3.3.43890 > 188.8.131.52.53: 61589+ SRV? _http._tcp.security.debian.org.

Packet forwarding is disabled:
# sysctl net.ipv4.ip_forward net.ipv4.ip_forward = 1
I run out of ideas… what am I doing wrong?
Thanks in advance!
