Unable to Access Internet from Debian Squeeze install on Dell R710

I've modified the /etc/network/interfaces file to show several variations of the following:

auto eth0
allow-hotplug eth0
iface eth0 inet static
address <>
netmask <>
broadcast <>
gateway <>
dns domain lan
dns-nameservers <>

The addressing is fine as this is in a corporate network and on an existing customer's Vlan. I've tried every different variation as suggested on the Debian wiki for network setup and when I run a ps -ef | grep networkmanager there is a process running, but I cannot find the networkmanager.conf file which is supposed to be in /etc/networkmanager/networkmanager.conf, but cannot find where this file is in Debian Squeeze to change [ifupdown] managed = true (false)

I can ping the gateway and loopback, but after starting and stopping networking I still cannot ping or any other public IP or site. If someone could point me in the right direction so that I can get Apache and mysql installed to hand off to management I'd be much obliged. Additionally, where do I specify ssh access in the ssh_config file in debian squeeze? Can't seem to find where this should be via the debian wiki or 'man ssh_config'

I should also add I've verified the resolvconf process is running and the appropriate firewall rules have been added to allow www access.

How about turning off the firewall to see if that helps.

Ssh access would not be configured in ssh_config - that's for the ssh client. You need /etc/ssh/sshd_config

Unfortunately, I cannot turn of the firewall... But, there is only two lines in the ACL for www and https and tried accessing the web before any rules were applied - no ingress or egress filtering - no outbound restrictions. As for the ssh configuration, I was just having a bit of an issue with where to place the users who needed ssh access in the /etc/ssh/ssh_config file.
