Can I set this new subnet IP on the existing WAN interface as an Alias? Usage of this new additional subnet is for static NAT on a host. If yes, how to configure default gateway address of this new subnetting?</P> Thu, 14 Apr 2022 06:22:32 GMT https://community.checkpoint.com/t5/Firewall-and-Security-Management/Alias-can-be-a-different-subnet-IP-address-from-real-interface/m-p/146252#M23204 Baasanjargal_Ts 2022-04-14T06:22:32Z https://community.checkpoint.com/t5/Firewall-and-Security-Management/Alias-can-be-a-different-subnet-IP-address-from-real-interface/m-p/146334#M23205 <P>It is enough for the ISP to route this subnet to your existing WAN IP as a next-hop and then you can configure the NAT. No alias interface is required here.</P> Fri, 15 Apr 2022 01:22:11 GMT https://community.checkpoint.com/t5/Firewall-and-Security-Management/Alias-can-be-a-different-subnet-IP-address-from-real-interface/m-p/146334#M23205 Chris_Atkinson 2022-04-15T01:22:11Z https://community.checkpoint.com/t5/Firewall-and-Security-Management/Alias-can-be-a-different-subnet-IP-address-from-real-interface/m-p/146551#M23279 <P>ok, thanks&nbsp;</P> Wed, 20 Apr 2022 07:31:52 GMT https://community.checkpoint.com/t5/Firewall-and-Security-Management/Alias-can-be-a-different-subnet-IP-address-from-real-interface/m-p/146551#M23279 Baasanjargal_Ts 2022-04-20T07:31:52Z
