Hi, <br />
We are currently looking at implementing a PIX to ASA upgrade on our network. There are two ISL's in place (alternate provider) and will connect to the new ASA's individually. We also require a failover mechanism between both firwalls and an active connection from both to the<br />
our DR site. The option currently being looked at is to implement a third ASA. The DR site is firewalled and if third ASA is not put in place there will only be a link from the DR site to one local firewall. This will not satifsfy failover requirements as if the firewall linked to DR goes down, how will fail over take place? Are there other options available apart from third firewall, hardware must be cisco. Thanks in advance.

Alternative to buying and implementing a third Cisco ASA for failover.

Web conferencing describes various types of online collaborative services including web seminars ("webinars"), webcasts, and peer-level web meetings. In general, web conferencing is made possible by Internet technologies, particularly on TCP/IP connections. Services may allow real-time point-to-point communications as well as multicast communications from one sender to many receivers. It offers data streams of text-based messages, voice and video chat to be shared simultaneously, across geographically dispersed locations. Applications for web conferencing include meetings, training events, lectures, or presentations from a web-connected computer to other web-connected computers. Popular titles include GoToMeeting, Cisco WebEx, Microsoft Lync, TeamViewer and Skype.

Hardware-based firewalls provide more sophisticated protection for inbound and outbound traffic than the simple Windows software firewall or the basic NAT firewalls found in routers. These devices implement techniques such as stateful packet inspection, deep packet inspection, and content filtering; and may include built-in antivirus and anti-malware protection.
