Editing the VTI network pool

When a route-based VPN topology is being created, the SMC server selects the IP addresses of IPsec VTIs from a private sub-network defined by default.

This sub-network is a reserve of available addresses and must be included in (or equal to) one of these three sub-networks:


The sub-network suggested by default is

This default network pool is the same across all topologies. If necessary, you can edit the global pool, or a pool specific to a topology.

If you edit a topology’s network pool of IPsec interfaces after the topology is created and deployed, you should verify the configuration of the interfaces already created on your firewalls, if SMC does not manage the network configuration.
