 - VPP dataplane must be configured.
-- VPP {doc}`IPsec settings </vpp/configuration/dataplane/ipsec>` should be configured as needed.
-- IPSec should be configured in the VPN configuration section, see {doc}`/configuration/vpn/ipsec/index`.
-- Both source and destination of the IPSec traffic must be reachable via VPP interfaces, so it can perform both encryption and decryption of the traffic.

 Improper IPsec configuration can lead to various issues, including:
 - **Unidirectional traffic flow or acceleration**
 
-  If kernel has a conflicting route for the remote subnet, such route may take precedence over the policy route created for the IPsec tunnel in VPP. This may lead to unidirectional traffic flow or acceleration only in one direction. This has no security impact because traffic will still be encrypted by the kernel, but it may lead to performance degradation. To avoid this, ensure that no conflicting routes exist in the kernel routing table.

 - **Conflicting with kernel routes**
 
-  If the kernel routes synchronization option is enabled, VPP will install all the routes from kernel.

 - **Unsupported algorithms**
 
-  If you have configured ESP profiles with algorithms not supported by VPP and the traffic for such peers flows through VPP interfaces, such traffic will be dropped. You can check system logs for messages from VPP with `linux-cp/ipsec: Invalid/Unsupported crypto algo` or `linux-cp/ipsec: Invalid/Unsupported integ algo` line to identify such cases.

 - **Connection is established but no traffic flows**
 
-  Even if you use compatible algorithms, there can be other reasons why traffic is not flowing. One of most frequent is blocking traffic between peers - that is especially common in public clouds. Make sure that TCP/UDP ports 500 and 4500 and ESP protocol are allowed between the peers. Alternatively, consider enforcing UDP encapsulation on both sides of the tunnel:
