Hi, we recently disconnected our Cisco firewall ASA 5510 when upgrading to a new T3 line through our ISP Qwest. Qwest informed us we no longer needed our firewall, and we provided configuration for the firewall to qwest. They said they have a firewall on their own network and to call them should i need any configuration changes.
My question is, did i make a mistake removing my Cisco firewall and going to qwest, does this leave me open or vulnerable to attacks? We have over 50 clients and 4 servers on our network. Thanks, any advise would be greatly appreciated.
