Summary: All in all its a great unit. This thing has the capability to do so much if you wanna put 2 grand into it. I like that it comes stripped down so someone like myself can pick it up for home use and still get it at a reasonable price. If they would just make a model with a 1G external interface and IDS for around $600 id be in heaven.
Pros: Use this at home for Firewall/VPN ( a bit overkill I know)
Cons: -The DMZ is somewhat limited (you have to deny all access to one Vlan if your going to use it, not a problem since my DMZ is for my seperate guest network VLAN)
Summary: I have installed 4 of this on various sites (3 are 10 users and 1 has 50 user licenses). The 10 user license is cheaper but I would recommend this one to cover growth (trust me i learned this the hard way).If you exceed your license limit the device will drop hosts randomly and it’s a pain to trouble shoot if you overlook the license limit. The device is very stable ,site to site VPN is always up.
Pros: Its cisco.
Cons: Only 2 SSl VPN licences, i wish Cisco gave more.
Summary: As usual, Newegg gets their products delivered fast and offers great prices.
Pros: This Cisco security appliance (firewall) model is well made and fully featured to meet the needs of most small and medium business users. It can be made operational with minimal changes to the default and auto-detect options. My unit came with the most recent firmware (8.3) installed which was helpful.
Summary: Make sure you understand the challenge of setting up a product this complex and the need to purchase a support contract if you want continued support. This isn't a home product... it's designed for business use and you have to pay for the worldwide 24/7 support you receive. On the other hand, you actually get 24/7 support from people who know what they're doing.
Pros: Good, solid product. Not as fast as the large ASA devices, but plenty for a home office or small office.
Cons: According to the specs, this is the old 256MB memory version. Cisco is currently shipping this model with 512MB. The current release of the software requires 256MB _minimum_, so you may not be able to run the next version on this hardware. I ended up spending a bit more to buy this somewhere else to get the new 512MB version. (see http://www.cisco.com/en/US/prod/collateral/vpndevc/ps6032/ps6094/ps6120/product_bulletin_c25-586414.html)
Summary: Someone mentioned VLANs. You can unlock the full 20 VLAN capability and full firewall rules for any direction traffic between any VLAN with the "Security Plus" license upgrade, but it is not cheap...
Pros: I have installed several of these for clients. Will do almost everything the larger ASAs will, just smaller.
Cons: Not for the inexperienced. Has basic NAT configured so you can "just plug it in" and get internet, but if that is all you are doing you are wasting your money.
