Hi all

It seems the order of precedence for IP address assignments for ASA and IOS.

Configuring an Easy VPN Server to Obtain an IP Address from a DHCP Server

When the Easy VPN server selects the method for address assignment, it does
so in the following order of precedence:

*1. *Selects the Framed IP address

*2. *Uses the IP address from the authentication server (group/user)

*3. *Uses the global IKE address pools

*4. *Uses DHCP

Configuring an IP Address Assignment Method

The security appliance can use one or more of the following methods for
assigning IP addresses to remote access clients. If you configure more than
one address assignment method, the security appliance searches each of the
options until it finds an IP address. By default, all methods are enabled.
To view the current configuration, enter the *show running-config all
vpn-addr-assign *command.

•aaa*—*Retrieves addresses from an external authentication server on a
per-user basis. If you are using an authentication server that has IP
addresses configured, we recommend using this method.

•dhcp*—*Obtains IP addresses from a DHCP server. If you want to use DHCP,
you must configure a DHCP server. You must also define the range of IP
addresses that the DHCP server can use.

•*local**—*Use an internal address pool. Internally configured address pools
are the easiest method of address pool assignment to configure. If you
choose local, you must also use the *ip-local-pool* command to define the
range of IP addresses to use.

To specify a method for assigning IP addresses to remote access clients,
enter the vpn-addr-assign command in global configuration mode. The syntax
is vpn-addr-assign {aaa | dhcp | local}.



With regards
