Question, can two firewalls from different communities "talk to each other"?&nbsp; In the other words are IPSec settings important locally (within domain) or in exchanging traffic between 2 communities as well ?</P><P>thank you</P> Wed, 01 Jul 2020 18:03:39 GMT marcinw 2020-07-01T18:03:39Z https://community.checkpoint.com/t5/General-Topics/2-communities-with-different-IPSec-settings-and-traffic-between/m-p/90338#M18066 <P>Hi</P><P>There are 2 communities 1st mesh and 2nd Star , they have different IPSec settings that are being used in both domains to create IPSec VPn tunnels.
