This is really annoying. I do expect to get a functioning product, yet, when I use the auto-installer of the latest distro STABLE SNG7-PBX-64bit-2011-5 on my server, it does not assign an ipv4-address to the system and therefore I cannot reach the GUI after installation. The current network configuration shows eth0, a Mac address and an IPv6 address. So, what do I do?
Your DHCP server serves IP addresses it is up to you as to whether it serves IPV4 and/or IPV6 addresses, either way they are not DNS servers. Some software packages, DNSMASQ for example can serve both roles though.
