14.17.1 Local and Remote IP Address Conflict Resolution

Normally, you do not configure your local VPN policy rule’s IP addresses to overlap with the remote VPN policy rule’s IP addresses (see Section 14.6.2 on page 319). For example, you usually would not configure both with 192.168.1.0. However, overlapping local and remote network IP addresses can occur with dynamic VPN rules or IP alias.
