Will a VPN Connection Be Re-established After Its Configuration Is Modified?
A VPN connection consists of local subnets, customer subnets, customer gateway, pre-shared keys (PSKs), IKE negotiation policy, and IPsec negotiation policy. A VPN connection is modified if any of the following happens:
- If the local and customer subnets are modified, the connection ID will remain unchanged. If not all subnets are updated, the established tunnel between subnets will not be re-established.
- If the IP address of the customer gateway is changed, the connection ID will remain unchanged, but the VPN connection will be re-established.
- If only the PSKs are changed, the connection ID and status will remain unchanged. The PSK will be checked again during renegotiation. If the PSKs do not match, the renegotiation fails.
- If a negotiation policy is modified (PSK verification is required), the connection ID will be changed and the connection needs to be re-established.
