But I'm not sure, it was already set up like this.</P> Fri, 03 Feb 2023 12:45:32 GMT https://community.checkpoint.com/t5/Firewall-and-Security-Management/Problem-creating-the-interfaces-for-a-vpn-on-an-FW-1800-splunk/m-p/170268#M30861 Luis1980 2023-02-03T12:45:32Z Re: Problem creating the interfaces for a vpn on an FW 1800 splunk https://community.checkpoint.com/t5/Firewall-and-Security-Management/Problem-creating-the-interfaces-for-a-vpn-on-an-FW-1800-splunk/m-p/170298#M30867 <P>If you need a different IP address for VPN purposes, you need to configure it here (versus create an alias interface):</P> <P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="image.png" style="width: 999px;"><img src="https://community.checkpoint.com/t5/image/serverpage/image-id/19443i44E7D2BAF60F1815/image-size/large?v=v2&amp;px=999" role="button" title="image.png" alt="image.png" /></span></P> <P>Otherwise, please provide more details about your existing configuration and the desired configuration.</P> Fri, 03 Feb 2023 19:27:39 GMT https://community.checkpoint.com/t5/Firewall-and-Security-Management/Problem-creating-the-interfaces-for-a-vpn-on-an-FW-1800-splunk/m-p/170298#M30867 PhoneBoy 2023-02-03T19:27:39Z
