How do you go about sizing a firewall for a given client? Right now I have a client that's only 5 users, and they $1,000 for a firewall would be pushing it.
The only fancy thing they need is the ability to let exchange and terminal server ports to be mapped to the internal IP addresses. Would something like a cablemodem/dsl router be sufficient in a case like this? If it depends, what does it depend on? Thanks in advance.
