I have a 2820n, in the UK running on Xilo with Three as 3G backup.

I've read the FAQ for DNS (http://www.draytek.co.uk/support/kb_vigor_dns.html) and I have some DNS questions.

1. Our company has DNS servers which resolve internal IP addresses. When I'm connected on the VPN, I need these. However if the VPN isn't connected, I need to use public DNS. Is this possible?

2. Can more than 2 DNS servers be configured?

3. Can the Vigor act as a DNS forwarder?

Thanks.
