topic The VPN client cannot connect to the device CP1575 in SASE and Remote Access https://community.checkpoint.com/t5/SASE-and-Remote-Access/The-VPN-client-cannot-connect-to-the-device-CP1575/m-p/265855#M1380 <P>Hello!<BR />I replaced my CP1450 device with a CP1575.<BR />Now all VPN clients (Win &amp; Android) can't connect to it: TCP-port 4433 is closed on the new device. Even with an explicit rule, the port doesn't respond. Perhaps OS R81.10.17 uses a different port than 4433?<BR />Thanks.</P> Sun, 21 Dec 2025 12:39:24 GMT PavelSpiridonov 2025-12-21T12:39:24Z The VPN client cannot connect to the device CP1575 https://community.checkpoint.com/t5/SASE-and-Remote-Access/The-VPN-client-cannot-connect-to-the-device-CP1575/m-p/265855#M1380 <P>Hello!<BR />I replaced my CP1450 device with a CP1575.<BR />Now all VPN clients (Win &amp; Android) can't connect to it: TCP-port 4433 is closed on the new device.
