Title: DFL-860E configuration problems with WAN2 and NAT
Post by: avgoustinosc on April 16, 2015, 09:13:46 AM

Dear All, we just installed at a client a DFL-860E with latest firmware with the following simple setup.

WAN1 with ISP-A
WAN2 with ISP-B
Site-to-Site VPN with a remote site

Internet on end users works perfectly, VPN is OK.

The problem is the following: We need to create a NAT rule for WAN2 so every request that comes on WAN2 with port 3299, will be redirected to ip address 192.168.1.115.
Issue 1: I cannot ping the public IP address of WAN2 even though i can ping the public IP address of WAN1.
Issue 2: I cannot find how i can "enable" WAN2 in order to be able to ping it from outside and also be able to use load balancing. ( i already tried priority from the manual).
Issue 3: How do i do a NAT so every request that comes on port 3299 on WAN2 will go to IP 192.168.1.115?

Any help on the above will be appreciated.

Thanks.

• What Hardware version is your DFL? Look at sticker under the router case.
• Link>What Firmware (http://forums.dlink.com/index.php?topic=47512.0) version is currently loaded? Found on the DFLs web page under status.
• What region are you located?

Internet Service Provider and Modem Configurations

• What ISP Service do you have? Cable or DSL?
• What ISP Modem Mfr. and model # do you have?

If the ISP modem has a built in router, it's best to bridge the modem. Having 2 routers on the same line can cause connection problems: Link>Double NAT (http://www.practicallynetworked.com/networking/fixing_double_nat.htm) and How NAT Works (http://computer.howstuffworks.com/nat.htm). Call the ISP and ask to see if the ISP modem can be bridged. To tell if the modem is bridged or not, look at the routers web page, Status/Device Info/Wan Section, if there is a 192.168.0.# address in the WAN IP address field, then the modem is not bridged. If the modem can't be bridged then see if the modem has a DMZ option and input the IP address the router gets from the modem and put that into the modems DMZ.
