I purchased this Load Balancer to solve the issue of having two networks in my office. It has successfully done this but I cannot access my local servers that I have port forwarded. I also have two routers, one extender and a small dumb switch. I have cascaded one router by setting it not to have DHCP running.

Both WANs are fibre but from different ISPs. I have plugged in these in WAN ports in the device and set all needed setting for two WANs. From this TL_R470T+, I have connected another router(I have configured this router simply disabling DHCP and giving it internet through its LAN port instead of WAN port) from one of the LAN ports, this supply WiFi for users in office. From the main LAN port, I have connected a cable into my server. The one left LAN port, am planning to connect a small switch from where I can plugin another router.

The connection works well but I cannot access my local server port forwarded.

NAT is off in second router and I can ping the server locally


 
You say you have port forwarded to your server. I have not used the load balancer router you have. How did you solve the problem of which ISP the server is using. Your server has 2 different external IP addresses depending on which ISP is being used. In theory you could forward both but then how does the traffic know to go back to the proper ISP from the server. Is this something you must configure or does the router have some "magic" way to solve this.

I have one server but I have created 10 virtual servers from it using VMSPHERE software. Each has its own IP. Please see attached image for reference.

Hi, The router supports two ISP , infact can support upto 4. However I have set the two I have. When setting port forwarding, it allows you to select which WAN you want to use for that. See its status page: (The two wans are down because I have not connected them now as i screenshot, when connected all is fine)https://drive.google.com/open?id=0B8DM6V7R0C4wdFBSREczbjVQXzA
and the port forwarded

There are so many places that this can have issues. First be sure that you are allowed by your ISP to even receive traffic on certain ports. Many ports like 25 and 80 are blocked by ISP. Way too many people THINK they can set up a server and then that server gets compromised and used to attack others. The ISP just do not want to deal with this and block these ports.

Next you need to see how far the traffic is making it into the site. You need to run something like wireshark on your server and see if you even get the packets. It would be nice if the router has some similar feature. You might be able to put in firewall rules and see if there are log entries. You might be able to put in "allow" rules just to get log entries. Deny ones generally are logged but that does not help as much other than to actually see the traffic.

Last how are you testing this. You must test from a actual outside device. Trying to go to the outside ip address from a inside device does not work on many routers.

Thanks guys for your response. Previously I had these setting in a router (D-LINK ROUTER) that connected to WAN 1 and everything was working fine. Could these setting that worked then and still works if I reconnect back fail in another router?

I am sorry I haven't yet stated my objective in this new architecture. I wanted users connected in WAN1 and WAN2 to communicate and access the servers and printers. I opted to purchase this router, which is a load-balancing router to integrate the two.

I was testing on my phone that is not connected to this internal network.
