is port forwarding enabled?

Thanks and I apologize as well, but the way customer service explained it to me is that the modems they use was not built with those options and a router gives you access to those options and on the times it doesn’t, it kind of tricks the modem. 
he told me that everything I need to set up, do it with the router… I was skeptical as well but it looks like it opens the ps4 ports for playing and a couple of them it wouldn’t due to security.

Just to double check, your Tmobile Gateway is the 5G one that looks like a short black squareish tower? (slightly rounded square edges) model KVD21?

It’s black tower says Arcadyan  gateway on the bill

It seems to me that the T-Mobile gateway (I have the 5G black square box model KVD21) does not allow for any kind of dhcp modifications but most importantly does not allow for Port forwarding.

I have several ports from the outside world that I need to forward to one of my internal PCs. It does not seem like the gateway automatically forwards these ports on to my local router (using ethernet WAN to connect to my router).

To me this is a massive oversight in T-Mobile's home internet rollout. Advanced users need the flexibility to set up their home network however they need to. At the very least I would have hoped that the gateway could just forward on all the traffic to my router and at my router handle it.

If T-Mobile doesn't come out with a solution soon, then I am thinking it's a deal breaker and I have to cancel their service and go back to cable :(

 

I agree.  What were they thinking no port forwarding?   NO DHCP reservations either.
