topic ASA Active/Standby using physical devices and virtual firewalls in Network Security https://community.cisco.com/t5/network-security/asa-active-standby-using-physical-devices-and-virtual-firewalls/m-p/4755314#M1096795 <P>Hello.</P><P>I have a network with three Cisco 5516 firewalls that have not been virtualized. We now want to introduce redundancy by implementing Active/Standby pairs for the firewalls. Can we use one 5525 ASA and virtualize it so that the standby firewalls are implemented as three virtual contexts in the 5525? in other words, can an active/standy pair be between a physical firewall and a logical firewall?</P><P>Regards.</P><P>&nbsp;</P><P>&nbsp;</P> Mon, 16 Jan 2023 10:44:17 GMT vitumbiko nkhwazi 2023-01-16T10:44:17Z ASA Active/Standby using physical devices and virtual firewalls https://community.cisco.com/t5/network-security/asa-active-standby-using-physical-devices-and-virtual-firewalls/m-p/4755314#M1096795 <P>Hello.</P><P>I have a network with three Cisco 5516 firewalls that have not been virtualized.
