Shaw uses CG-NAT? Cannot connect to my servers!

[scypheroth]

So i have multiple server pc's in my home that i use to host media content and game servers...recently i have been getting complaints that my friends and colleges cannot connect to my servers. I look into it and my IPv4 address is NOT the same as my Routers IPv4 address and my port forwarding IS NOT taking due to this...my shaw modem is set to Bridge mode and i do all my port forwarding on my alternate router. 

All indications are pointing to Shaw using CG-NAT on there systems wich is resulting in my issues, is there any way to get my ip address set to a static ip OR disable the CG-NAT on my account. If this cannot be done im going to need to switch service providers as i cannot have no access to my servers.

AND NO its not my router as i have formatted it MULTIPLE times and set it up MULTIPLE times and also bough ta totally new router asides from this one to troubleshoot with and it was the same on that router.

As you can see my shaw modem and router IPv4 addresses are NOT the same this is resulting in my port forwarding not taking. and NO the factory shaw modem isnt a option as it dosnt have enough ports to accommodate my needs and lacks external USB support.

@scypheroth , I can only answer part of your question.  A static ip can only be obtained with a Rogers/Shaw business account and not a personal home account.  Sorry not much help otherwise, but maybe someone else will chime in.

@scypheroth -- I see your screen-capture:

When you request a packet from the Internet, it is sent to that ".1" router, somewhere in your neighbourhood.

That router forwards the packet to your Shaw cable-modem with the ".74" IP-address. If your neighbour is also a Shaw customer, their cable-modem/router might be dynamically assigned a ".75" IP-address.

However, I think that Shaw has provisioned your account with the capability of having 2 IP-addresses, namely the ".74" for the Shaw cable-modem, and the ".123" for your ASUS router.  

I presume that the "uplink" port on the ASUS is Ethernet-connected to one of the "LAN" ports on the cable-modem. Incoming traffic for ".123" goes "through" the cable-modem, out that LAN port, and into the WAN port on the ASUS.

Note that your ASUS has communicated with a Shaw DHCP-server, and that server assigned the ".123" IP-address.  So, you have Internet connectivity from the ASUS (and from all the devices connected (wired or WiFi) to your ASUS.

So, if your colleagues somewhere on the Internet want to connect to your "game-server", they need to send to the ".123" IP-address, and your ASUS must "forward" those incoming packets to one of the "private network" devices connected to your ASUS.  Is this happening? Can your colleagues use the PING command to try to get PING-responses from that ".123" IP-address?  If so, can they connect to your "game-server"?

Note that your ASUS must be configured to "forward" incoming packets to the "private" IP-address (maybe something like "192.168.xxx.yyy"), instead of "dropping" those incoming packets. Check the configuration. Check the "private" IP-address of your game-server.

If you have the latest XiOne/Xi6 TV boxes, your cable-modem is still providing WiFi networking to your TV box(es), even when "bridged".  Those boxes connect to the ".74" IP-address, and in/out to the Internet.
