VPN Configuration
NAT Mode
NAT mode should be used in site-to-site VPNs, where bi-
directional initiation of traffic between networks using private IP
addresses is required.
The Figure below shows two instances of a site-to-site VPN
gateways in NAT mode.
Figure 12 NAT Mode
Solution A: IP30 Satellite to VPN-1 (Site-to-Site
VPN)
Hosts on Network 1 establish the TCP/IP connection to the external
IP address of the IP30 Satellite site-to-site VPN gateway. The IP30
Satellite device is configured through the IP30 GUI Security page
to port forward the inbound traffic to the defined host.
Solution B: Satellite to Satellite (Site-to-Site VPN)
IP30 Satellite supports the creation of site-to-site VPN connections
between two or more IP30 Satellite devices. Hosts on either
network can directly initiate traffic to hosts on the peer network.
The IP30 Satellite is configured through the IP30 GUI Security
page to port forward the inbound traffic to the defined host.
