Multi WAN of same ISP - 200D (v5.4.4)

Hi all,

Please help me the following case as picture on FTG 200D. I have 2 internet line of same ISP (same gateway) and this is what I want for my network:

- 192.168.1.x -> WAN 1 (static ip)

- 10.1.1.x -> WAN 2 (static ip)

- Route 2 network layer above

As succeeded, 2 networks see each other, in/out through WAN 1 is OK, but I just can make out through WAN 2. The problem is that I cannot ping ip of WAN 2 from outside and cannot access 10.1.1.x through WAN 2 from outside.

Please help me config this in GUI.

Thanks,

Hoai An
