If the OP's using the network service rather than NM, then using
ifup/ifdown with ifcfg-p6p1 isn't outdated.

To the OP:

Is the problem that you're getting a dhcp lease from your "firewall"
but resolv.conf isn't being populated?

Are you using NM or network?

What's the content of
/etc/sysconfig/network-scripts/ifcfg-p6p1
/etc/dhclient.conf or /etc/dhcp/dhclient.conf (if they exist)
/etc/NetworkManager/NetworkManager.conf
/etc/NetworkManager/system-connections/your_connection (if it exists)
