I'd like to get my puppet master to manage nodes in a different vlan.

Due to firewall restrictions, I can't do this easily. I'm thinking of adding a 2nd NIC to the master server configured with an IP on the 2nd vlan.

Will this work? Can Puppet be configured to listen on 2 IPs?

Can it talk to nodes in the same vlan on the primary interface and to nodes in the 2nd vlan through the 2nd interface?

How do I configure the Master to listen on the 2nd interface and to communicate to nodes on the 2nd VLAN via the 2nd interface? Which config files should I look at?
