Access determines whether the Mesh Point will
Allow
(the
default) or
Deny
access to an authentication server whose
X.509 certificate matches the criteria specified in the ACL entry.
View the entries in the ACL using
show:
# show ipsec -acl

50 allow Test1
99 allow Test3
4 IPsec ACLs configured
Use the -counter switch to show the number of IPsec ACLs
configured.
To delete IPsec ACL entries:
NOTE: Deleting all
ACL entries dis-
ables the Mesh Point’s
IPsec ACL function.
# del ipsec-acl -all|-name

Deleted ACL entries no longer appear when you run show

4.4.6 L2TP/IPsec Connections
NOTE:
Incoming
L2TP traffic
requires administrative
access. If the adminis-
trative IP address ACL
(disabled by default) is
enabled, it must include
L2TP peer IP addresses.
See Section 2.2.5 for
more detail. Traffic is
affected by the per-
interface packet filters.
If configured, per-inter-
face packet filters must
include filters to permit
L2TP traffic to and from
the FMP. See Section
4.6.3 for more detail.
When a Suite-B license is installed and IPsec is enabled,
Layer 2 Tunnel Protocol (L2TP) functionality can be used to
establish an L2TP/IPsec tunnel from a client (L2TP Access
Concentrator, or LAC) to a server (L2TP Network Server, or
LNS). L2TP can be used to establish a virtual network, which
enables a remote host or other remote network to access an
enterprise network securely.
Based on a request from a remote device (LAC), an IPsec SA
will be established, the remote user will be authenticated, and
the L2TP tunnel session established. The tunnel session will
remain active until it is deleted by an administrator, or the IPsec
SA is deleted or expires.
Currently the ES210 Mesh Point can only serve as an L2TP
LAC, and the ES2440, ES820, and ES520 Mesh Points can
only operate in LNS mode. A given device can operate in either
LAC or LNS mode, but not both.
Mesh Points do not support L2TP/IPsec on radio BSS
interfaces enabled for wireless bridging (
EnableWds[Y]
,
described in Section 3.4.2). When L2TP is enabled, do not
apply an SPD entry (as described in Section 4.4.2, below) to a
wireless bridging interface.
The L2TP LNS uses the configured RADIUS server(s) on a
system, on which EAP-TLS must be enabled.
