We have a DrayTek Vigor 2830n plus which supports 3 simultaneous WAN connections (ADSL, broadband and USB 3G)
We are using two wan connections:
WAN1 is an ADSL which connects to the internet with single dynamic IP
WAN2 is connected to a Cisco 877 router which acts as a gateway to few subnets like (192.168.5.0/24). The Vigor WAN2 static IP is 192.168.101.2 while the Cisco 877 IP is 192.168.101.1
I have setup the LAN IP in Vigor to 192.168.0.250/24 and the routed subnet IP is 192.168.0.201/24
I have also setup load balancing to send traffic destining to addresses between 192.168.1.0 and 192.168.40.255 through WAN2
Now devices in the LAN subnet (192.168.0.0/24) can access devices through Cisco gateway (like 192.168.5.2). The problem is, devices like 192.168.5.2 can't access my LAN devices.
Can any DrayTek expert advice how to solve this?
