    Is there a way to create secondary IP addresses on an external interface?

      Hi,

       

      I'm wondering if there is a way on the Sidewinders to setup a secondary IP address on an external interface.

       

      I just recently got a new set of public IP address from my ISP for me to host some web servers but the IP addresses are not consecutive to the ones I previously had, therefore I don't want to have two external interfaces on my firewall.

       

      Example:

      A.B.C.97  with mask 255.255.255.248  (Original Public IP range given from ISP)

       

      A.B.C.177 with mask 255.255.255.240 (New Public IP range)

       

       

      Currently I'm trying to band-aid the interface by telling it that my primary external interface is A.B.C.178 /24 (which covers both IP ranges) but this gives me a bigger broadcast and may eventually cause me other problems.

       

      Any suggestions?

       

      Thanks.

       

      P.D. I'm running the sidewinders with version 7.0.1.02 on High Availability mode just in case.
