18.14.1 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 18.6.2 on page 369). 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.
