Q:
Can Cisco ASA firewalls restrict Internet access to branch offices?
Networking, Network security, Network security appliances, Internet connection, Servers, Branch Office networks, Branch offices, Firewalls, Proxy, Firewall appliances, Cisco ASA, Cisco ASA 5505, Cisco ASA Hardware Firewall I have a PPP network between our three office locations. In the master location I have a DSL line connected to my Layer 2 (L2) switch via a Cisco ASA 5505 Firewall. My server (ADC/DHCP/Proxy) is connected to the L2 switch. My branch office locations obtain IP through this server. I am using a Squid Windows version for my proxy, and I'm not able to restrict the Internet connection to branch offices using Squid. How can I restrict branch office users from using the Internet connection?

======================
I addition to the above you can control which IP's and protocols have connectivity to the internet via the ASA. Maybe set it up so that only you proxy has access to browse the Internet.
