topic Secondary IP outside interface PIX in Network Security https://community.cisco.com/t5/network-security/secondary-ip-outside-interface-pix/m-p/427275#M530692 <P>I have PIX 515 with a static address on the outside interface. I also have multiple sites with IPSEC connections to that pix. I want to provide some WAN redundancy with a second ISP. This requires me to have a second static address on the outside interface, is this possible? There appears to be no "secondary" address as in router IOS.</P> Fri, 21 Feb 2020 08:31:36 GMT rasoftware 2020-02-21T08:31:36Z Secondary IP outside interface PIX https://community.cisco.com/t5/network-security/secondary-ip-outside-interface-pix/m-p/427275#M530692 <P>I have PIX 515 with a static address on the outside interface.
