Configuring VPN Passthrough
VPN passthrough allows VPN traffic that originates from VPN clients to pass
through the router. For example, if you are not using a VPN that is configured on the
Cisco RV 110W, but are using a laptop to access a VPN at another site, configuring
VPN passthrough allows that connection.
To configure VPN passthrough:
STEP 1 Choose V
VPN
> V

STEP 2 Choose the type of traffic to allow to pass through the router:
•
IPsec
—Check E

•
PPTP
—Check E
Enable
to allow Point-to-Point Tunneling Protocol tunnels to
pass through the router.
•
L2TP
—Check E
Enable
to allow Layer 2 Tunneling Protocol tunnels to pass
through the router.
STEP 3 Click S

Configuring Security
The Cisco RV 110W provides several security methods, including certificate
authentication, RADIUS server support, and 802.1x port-based authentication.
Using Certificates for Authentication
The Cisco RV 110W uses digital certificates for IPsec VPN authentication and SSL
validation (for HTTPS and SSL VPN authentication). You can obtain a digital
certificate from a well-known Certificate Authority (CA) such as VeriSign, or
generate and sign your own certificate using functionality available on this
gateway. The gateway comes with a self-signed certificate, and this can be
replaced by one signed by a CA as per your networking requirements. A CA
certificate provides strong assurance of the server's identity and is a requirement
for most corporate network VPN solutions.
