3.In the IKE SA Parameters section of the screen, locate the DPD fields, and complete the fields as explained the following table:

Table 83. Dead Peer Detection settings

Setting	Description
IKE SA Parameters
Enable Dead Peer	Select the Yes radio button to enable DPD. When the UTM detects an IKE
Detection	connection failure, it deletes the IPSec and IKE SA and forces a reestablishment
	of the connection. You need to specify the detection period in the Detection
	Period field and the maximum number of times that the UTM attempts to
	reconnect in the Reconnect after failure count field.
	Detection Period	The period in seconds between consecutive
		DPD R-U-THERE messages, which are sent only when the
		IPSec traffic is idle. The default setting is 10 seconds.
	Reconnect after	The maximum number of DPD failures before the UTM tears
	failure count	down the connection and then attempts to reconnect to the
		peer. The default setting is 3 failures.

Configure NetBIOS Bridging with IPSec VPN

Windows networks use the Network Basic Input/Output System (NetBIOS) for several basic network services such as naming and neighborhood device discovery. Because VPN routers do not usually pass NetBIOS traffic, these network services do not function for hosts on opposite ends of a VPN connection. To solve this problem, you can configure the UTM to bridge NetBIOS traffic over the VPN tunnel.

To enable NetBIOS bridging on a configured VPN tunnel:

1.Select VPN > IPSec VPN > VPN Policies. The VPN Policies screen displays (see Figure 181 on page 301).

2.In the List of VPN Policies table, click the Edit table button to the right of the VPN policy that you want to edit. The Edit VPN Policy screen displays. (The following figure shows only the top part of a UTM50 screen with the General section).
