I followed all the steps, still can't do port forwarding on any other IP assigned beside the IP associated with the first router. Would this have anything to do with the features assigned to the main IP that the modem has? Maybe once I set all my port forwarding rules on the first router no other IPs would have that feature because the modem IP would prevent that?

I also bought a multiple WAN router in order to do port forwarding on WAN1 and WAN2. It won't open any ports on any of the 2 Wan IPs. I guess the modem is trained to do that only on the IP associated with the Mac address of the first router. If I connect that back to the modem, it'll get the same IP and the rules I created are ok, my ports are open.

I'm thinking if it's something that needs to be modified in the IP table on Shaw's end?

@Spartan01 -- ,till can't do port-forwarding on any other IP assigned beside the IP associated with the first router. 

Do not try to use the BlueCurve app to configure any of your 3 routers.

Instead, connect a computer to a LAN port on the computer, and access your router's web-interface, to define the port-forwarding. Example for http://192.168.0.1 (my router)

@Spartan01 -- I also bought a multiple WAN router in order to do port forwarding on WAN1 and WAN2.

Have you used Ethernet cables to connect the two ports on the Shaw router to the two WAN ports on your router?

Does your router show the two "public" IP-addresses that Shaw's DHCP-server has allocated to your router?

> It won't open any ports on any of the 2 Wan IPs.

Again, are you accessing the web-interface on your router, to define the port-forwarding?

> I'm thinking if it's something that needs to be modified in the IP table on Shaw's end?

I am not thinking that. The only "table" is within Shaw's DHCP-server, to ensure that EXACTLY one customer device is assigned to a specific IP-address. You don't want two customers to get the IDENTICAL IP-address.

I'm always using web interface.

I have 2 ethernet cables connected from the 2 ports from the XB6 modem to the 2 WAN ports on the router. And, yes, I can see the 2 WAN IP addresses on the router's WAN page. 

For some reason only the IP assigned to the very first router does port forwarding. Other than that none of other ones do. 

Should I factory reset the XB6, put it back on bridge modem and try the multi WAN router first? That way it will delete any previous IP assignments I guess. Thoughts on that?

@Spartan01 --  I'm always using web interface

I presume that you are using a computer connected to your router to access your router's web-interface (http://192.168.xxx.yyy), not connecting to the web-interface inside the Shaw router (via http://10.0.0.1 )

I have 2 Ethernet cables connected from the 2 ports from the XB6 modem to the 2 WAN ports on the router. 

Yes, I can see the 2 WAN IP addresses on the router's WAN page. 

So far, so good.

For some reason, only the IP assigned to the very first router does port forwarding.

Does the web-interface on that router allow you to choose between the 2 WAN IP-addresses, and then configure that IP-address, to add the port-forwarding? 

Since you only have one router, any port-forwarding that you define may apply to incoming traffic via either "public" IP-address -- "all incoming traffic from either WAN interface is port-forwarded to the private IP-address 192.168.0.123".

I sense that there may be a problem here:

1. computer sends a packet through WAN port #1 (with its IP-address) to some server on the Internet;
2. server responds to your first IP-address;
3. your computer sends another packet to the same server;
4. your router chooses to route your packet through WAN port #2 (with its different IP-address) to the server;
5. the server sees the traffic from the 2nd IP-address as NOT being associated with your previous packets sent from your 1st IP-address
6. the server treats your 2nd packet as being a different computer

Hmm. Does the router "always" use WAN port #1 when communicating to that specific server? Or, does it pick the outgoing WAN port that seems to be "better/faster" ?

Other than that none of other ones do. 

If you are back to using two routers, then use one computer connected to the first router to define the port-forwarding, and use a different computer connected to the second router to define the port-forwarding. Do you need port-forwarding on both routers? Do you have two servers -- one per router -- or just one server?

Should I factory reset the XB6, put it back on bridge modem and try the multi WAN router first? That way it will delete any previous IP assignments I guess.

How "smart" is that multi-WAN router? Does it use both connections, in a "round-robin" way, or does it "prefer" one WAN port, until it fails, and then "falls-over" to the second WAN port, to maintain Internet connectivity?

That's correct since there's nothing else you can configure inside the Shaw router since it's in bridge mode.

Do you need port-forwarding on both routers? Do you have two servers -- one per router -- or just one server?

This is scenario 1 with 2 separate routers connected to Shaw router, each router has its own network. That way I have a network with 192.168.0.x and the other one 192.168.1.x. Port forwarding works on router#1, private IP 192.168.0.x. I always check what public IP is on that network and if the port is open or closed. (whatismyip.com and port checker.co as an example). Exact same port I needed forwarded to a private IP on the second network, 192.168.1.x. 

What I noticed last night though, I tested port 22 and the DNS port on router#2 and it opened them both. Other that these 2, none, all closed.

Scenario 2 now, both public IPs connected to the multi-wan router. It uses both WAN IPs the same time,  and you can specify which LAN port to associate with which WAN IP address and what private IPs you want. Anything I try to do on this router, doesn't open. Obviously I get 2 different public IPs than the ones associated with the 2 separate routers from scenario 1.

So, we have 3 public IP in total here. Router#1, router#2 and Shaw router. What if the Shaw router's public IP needs a specific configuration on Shaw's end, a re-set or something. It's strange that only the IP associated with router#1 does the job. Is the Shaw router's IP configured as a "gateway" for the other 2?
