DNS works correct?

[dannymagat]

yes dns is correct.
In v2 rev.9347 works fine by the way. the only problem im facing on that revision is not not getting ip from dhcp server which is on the other edge.
Is there any special config?

After study of a code I clarified that it is possible to use only IP-addresses, not hostnames. It is a payment for compatibility between IPv4 and IPv6.
