23.3 Interconnection of two private networks via the Internet (VPN tunnel)

295

Note: VPN tunnels keeps their connection (by sending special packets in regular time intervals)

even if no data is transmitted. This feature protects tunnels from disconnection by other

ﬁrewalls or network devices between ends of tunnels.

Traﬃc Policy Settings for VPN

Once the VPN tunnel is created, it is necessary to allow traﬃc between the LAN and the network

connected by the tunnel and to allow outgoing connection for the Kerio VPN service (from

the ﬁrewall to the Internet). If basic traﬃc rules are already created by the wizard (refer to

chapter 23.2), simply add a corresponding VPN tunnel into the Local Traﬃc rule and the Kerio

VPN service to the Firewall traﬃc. The resulting traﬃc rules are shown at ﬁgure 23.11.

Note:

1. To keep examples in this guide as simple as possible, it is supposed that the Firewall traﬃc

rule allows to access any service at the ﬁrewall (see ﬁgure 23.12). Under these conditions,

it is not necessary to add the Kerio VPN service to the rule.
