Company A - RS-2500 - WAN IP: 60.250.158.66, LAN IP: 192.168.10.x

Company B -

1.

PPPoA Modem Router - WAN IP: PPPoA with DDNS service enabled

2.

RS-2500 - WAN IP: 192.168.20.254, LAN IP: 192.168.30.x

This example takes two RS-2500s as work platform. The Company B of RS-2500 is

installed behind a PPPoA modem router and the WAN interface is set to private IP address.

So, the RS-2500 in Company B can create an IPSec VPN tunnel to RS-2500 in Company A.
