These three rules should be configured above all other rules (default or user defined). When
Advanced LAN Access is used, certain inbound/outbound rules need to be configured to
control incoming/outgoing packet flow for IPSec to work properly (with Advanced LAN
Access). These rules should be configured first before other rules are configured.
• Question 13: Do I need to add any special routes on the access point to get my VPN

No. However, clients could need extra routing information. Clients on the local LAN side
should either use the access point as their gateway or have a route entry tell them to use
the access point as the gateway to reach the remote subnet.
