Don't bump, either people will reply or they won't..
You still haven't explained why you want to setup a DNS server, what do you intend on doing with it? please explain your network topology and what you hope to accomplish.
- Is this system facing the Internet? Will it be a primary/secondary nameserver for a domain?
- Are you using it as a NAT firewall? Do you want a local caching nameserver?
- What led you to believe 2 network interfaces are required for proper operation of a DNS server?
You keep asking us vague questions without any context, so please explain why it's an "emergency".
I look forward to your response..
