Can't port forward for some reason
So I'm trying to port forward my rust server (video game not programming language) on port 28015 to play with some friends but I cant seem to get it working. I've exhausted pretty much all of my options like tweaking the firewall rules and changing various other settings. I'm using a tp-link archer c54 router and a comtrend ar-5220u modem and I even went as far as port forwarding on my modem too. I started to suspect that my ISP was blocking ports so I called them and they basically just told me they don't know and to call my router company. Also when I check to see if my port is forwarded on canyouseeme.org it tells me it can't see my service on port 28015 and connection times out. I'm just confused because I did everything properly and followed guide's on portforwarding but it still won't work. Any help would be greatly appreciated thank you!

So, this sounds like it may be a double-nat situation. If your modem has the ability to port forward, you may want to put it into a "pass-through" or "transparent" mode so your archer is your main router facing the internet.
It appears that for comtrend ar-5220u, it's specifically referenced as "bridge mode". Just be aware that it'll merely be the bridge between the ADSL line and your tp-link archer, so don't go too wild with the port opening, etc.
I suspect that after you do that, it'll work just fine.
So should I port forward on my router and modem or just my router?
Just your archer router and put your modem into bridge mode. Then make sure your cable goes from a white WAN port on your modem to the router, if it has it
Oh ignore the white WAN part, just have it go from ETH 1 on the modem to the router's blue WAN port
Also I'm not seeing any "pass through" or "transparent options on my modem and I can't find any guides for my specific modem but I suspect this may have something to do with it?
It'll be bridging
but hold on
Since it's pppoe, you may need to reach out to your ISP and get your PPPOE credentials and then set your WAN port to PPPOE and input those creds
@weet has reached level 1. GG!
Basically what'll ha-
fuck off arcane
Basically what'll happen, is your router will reach out through your modem, authenticate with your ISP using PPPOE and then pull down the IP and related information
Oh ok
This is my current WAN setup
I'm already using PPPoE
Yeah but PPPoE needs to happening on the router and your modem needs to be in bridge mode
I'm not sure about that specific modem model but I had a VDSL2 modem at my last place. I put my PPPoE creds into my FortiGate and my modem in bridge mode, so it'd handle everything and the modem was basically invisible
So just make a new WAN service with the bridging box checked?
Gonna be honest, I'm not entirely sure with that modem, specifically
You may wanna give your ISP a call and talk to a tech, they may give you better direction. Tell them you want your modem in bridge mode and you want your router to pull PPPoE creds so you're not doing double NAT
Oh ok
Thanks
Yeah, any time. If they're not very helpful, you can probably figure it out with a lot of trial and error but it'll be a little tedious
He said my modem doesn't support bridged mode?
Then he's full of shit and doesn't know what he's talking about lmfao
lmao yeah
I live in the middle of nowhere lmao
Your better option might be to just get a server from Oracle on their free tier and use that
It's pretty generous
my isp sucks
oh yeah like a cloud server?
also he said my router can't pull PPPoE creds to disable double NAT
wow
Either he's incredibly lazy and doesn't wanna help you or he's just ignorant and confident in his ignorance

You'll have to get your hands a bit dirty but these limits are very generous and if you are able to go with an ARM processor for the server, you get a pretty wicked powerful machine
Or just rent one from a GSP
Alright sweet thanks
Yeah, any time! Hopefully that somewhat points you in the right direction
Hey I know this is probably getting redundant for you but I just have one more question to ask and that's do you think my port forwarding would work if I upgraded to a new modem?
Potentially, yeah. As long as it has bridge mode but you have to get an ADSL modem and there aren't a lot on the market, if I recall. You'd need to get your PPPoE creds from your ISP, too.
But at the same time, your modem can already do bridge mode, it's just a matter of how is it done specifically on that one
Shit I forgot to ask them for my PPPoE creds dangit 😅
Call them back and politely tell the tech he's a fool

💀
Another option is to set your modem as your router, firewall, etc and just have your tp-link be a wireless access point
I just hopped outta the shower but to that point above ^ that archer user guide pdf shows how to do it
cool thank you
hahaha lmao
In the rust server config, is the port set to the one you're forwarding on?
