Sophos XG and Airtel FTTH with static IP address

Hi Lijo,

Thank you for your query, upon forwarding the VPN IPsec Ports: UDP ports 500 and 4500, can you confirm from the following website whether the ports are open or not ?

the scan showing that the ports 500 and 4500 are open/filtered.

Hi Lijo, A port is marked as "open|filtered" when the port scanner cannot determine whether it is filtered or open, and A port is marked as "filtered" when the packets are sent to that port, however packet filtering (e.g., firewall) prevents the packets from reaching that port.

how to open the ports. Is the VPN connection through 500 & 4500 UDP ports.

You can validate that by contacting ISP on both the sides, as VPN uses UDP 500 & 4500 Ports.
