Methods and apparatus that enable more than one server to host a resource using a shared IP address such that a client may generally access the resource on any of the servers using the shared IP address are disclosed. According to one aspect of the present invention, a method for providing paths that allow a client to access a resource in a TCP/IP network includes obtaining an IP address, as well as associating the IP address to first and second servers. The first and second servers support the resource at the IP address, and a first path of the plurality of paths that allow the client to access the resource is between the client and the first server and a second path of the plurality of paths that allow the client to access the resource is between the client and the second server.

Multipath routing process

Techniques are described to enable two or more layer two (L2) firewall devices to be configured as a high availability (HA) cluster in an active-active configuration. A first layer two (L2) firewall and a second L2 firewall are positioned within the same L2 network. The first L2 firewall and the second L2 firewall are concurrently configured with active virtual security devices (VSDs) within the L2 network, and concurrently apply L2 firewall services to packets within the L2 network. A VSD of one of the L2 firewalls automatically switches to an active VSD status for a VSD group in place of a VSD of another L2 firewall when the other L2 firewall fails.
