I have a client who runs a peer-to-peer network (he refuses to use servers...long story, don't ask). He is very anal about security and is in the process of upgrading parts of his network. I am now tasked with finding a firewall that meets, at a minimum, the following requirements:
Inbound/Outbound E-mail Scanning (SMTP/POP3), w/rules for attachment handling and other business requirements.
Internet websites blacklist/whitelist, granular settings by user/node/IP address. AD/DS is not and will not be used in this network.
Internet connectivity failover.
Dual power supplies, preferably hot-swappable.
Site-to-site VPN capability.
Graphical User Interface (GUI) for management. Does not want cloud management capability, if it does can it be turned off?
Thank you in advance for your recommendations/comments/snippets!!!
