Usually no policy would be needed for that, since it would not be crossing the firewall, BUT, just to be 100% sure, if traffic fails, you can examine the logs, just to make sure.</P> <P>Also, lets take basic example, this will prove the point without any doubt. Say host IP is 10.10.10.10, you can initiate traffic and while doing so, run tcpdump -enni any host 10.10.10.10 from expert mode and if you dont see anything, then its not even hitting the firewall at all.</P> <P>Andy</P> Fri, 18 Aug 2023 12:34:40 GMT https://community.checkpoint.com/t5/Firewall-and-Security-Management/Intra-vlan-communication/m-p/189872#M34994 the_rock 2023-08-18T12:34:40Z https://community.checkpoint.com/t5/Firewall-and-Security-Management/Intra-vlan-communication/m-p/189910#M35011 <P>Its 3400 series anyways it was not issue of firewall.</P><P>&nbsp;</P><P>cheers!</P> Sat, 19 Aug 2023 03:09:49 GMT https://community.checkpoint.com/t5/Firewall-and-Security-Management/Intra-vlan-communication/m-p/189910#M35011 pavan_kalal 2023-08-19T03:09:49Z https://community.checkpoint.com/t5/Firewall-and-Security-Management/Intra-vlan-communication/m-p/189925#M35015 <P>Good job! <span class="lia-unicode-emoji" title=":thumbs_up:">👍</span>✔</P> Sat, 19 Aug 2023 16:27:50 GMT https://community.checkpoint.com/t5/Firewall-and-Security-Management/Intra-vlan-communication/m-p/189925#M35015 the_rock 2023-08-19T16:27:50Z https://community.checkpoint.com/t5/Firewall-and-Security-Management/Intra-vlan-communication/m-p/189934#M35016 <P>Thanks to everyone and checkmate, for such wonderful platform where one can post his/her qeury -doubts and get instant real time solution.&nbsp;</P><P>cheers.. !</P><P>&nbsp;</P><P>&nbsp;</P> Sun, 20 Aug 2023 10:41:55 GMT https://community.checkpoint.com/t5/Firewall-and-Security-Management/Intra-vlan-communication/m-p/189934#M35016 pavan_kalal 2023-08-20T10:41:55Z https://community.checkpoint.com/t5/Firewall-and-Security-Management/Intra-vlan-communication/m-p/189935#M35017 <P>Glad we can help mate <span class="lia-unicode-emoji" title=":folded_hands:">🙏</span></P> Sun, 20 Aug 2023 11:28:33 GMT https://community.checkpoint.com/t5/Firewall-and-Security-Management/Intra-vlan-communication/m-p/189935#M35017 the_rock 2023-08-20T11:28:33Z https://community.checkpoint.com/t5/Firewall-and-Security-Management/Intra-vlan-communication/m-p/189938#M35018 <P>Hey&nbsp;<a href="https://community.checkpoint.com/t5/user/viewprofilepage/user-id/18403">@pavan_kalal</a>&nbsp;</P> <P>I attached a file I put together for some troubleshooting steps to take in relation to generic issues.
