Ports 21 and 22 are open but the rest are not.

astronovaval — Thu, 07 Sep 2023 07:17:13 GMT

Ports 21 and 22 are open just fine. I add ports 28015, 28016 and 28083 along side 21 and 22 but the 280XX arent opening, this is for setting up a Rust Dedicated Game Server.

using FAST 5364
the ports im trying to open
28015: UDP (Rust (game)

28016: TCP (RCON)
28083: TCP (RustPlus (game app extension)
Ive reserved the IP (192.168.1.10) for the machine running the game server
running netstat find has no output and just hangs.

Hi @astronovaval

@Anonymous has asked me to help you with this. I will test these ports out later this morning and get back to you.

EDIT! port 28016 seems to be open according to canyouseeme.org, the other 2 remain closed.|

also port 27015 also closed.

I have just tested these ports & they are all open:-

28015: UDP

28016: TCP
28083: TCP

UDP ports are not compatible with port-checking websites, they only work with TCP ports. I do have another more complex way of testing them though, hence how I have proved 28015 is OK.

As some of your ports are open when you test them, then you are obviously not falling foul of NAT Loopback. Please can you send me screenshots of what you have set up on the router's PF rules, so that I can check them for you? Have you allowed the ones still not working through any firewalls on your device (not the router's firewall)?

astronovaval — Thu, 07 Sep 2023 08:45:49 GMT

Ive allowed all the ports through the firewall on the machine as well.

They all look fine. What hardware & firmware revision is your 5364?

Re: Ports 21 and 22 are open but the rest are not.

astronovaval — Thu, 07 Sep 2023 08:53:55 GMT

Hardware Version: FAST5364 3.00

Software Version: SG4K100174

Thanks, no problems there. Can you try deleting the TCP one that does not work & then adding it again? How are you testing the UDP one? The only difference with mine is that I only ever set the protocol to TCP & UDP if it will use either, if not I always specify them exactly:-

My rules

Will i have to restart my router for these changes to take effect?

the UDP one is pretty easy to test, i have my other machine that cannot connect to the server via the public ipv4 address, only via the internal local ip of the server.

Re: Ports 21 and 22 are open but the rest are not.

KeithFrench — Thu, 07 Sep 2023 09:21:14 GMT

You shouldn't have to, but I did see someone the other day where it started working after a router reboot.

Re: Ports 21 and 22 are open but the rest are not.

KeithFrench — Thu, 07 Sep 2023 09:23:12 GMT

If you are trying to connect from a local device via the router's WAN IP address, that will never work, due to NAT Loopback blocking the port on its return to the router. I thought from one of your early posts that you were only trying a port-checking website.

astronovaval — Thu, 07 Sep 2023 09:31:31 GMT

still nothing.. still showing most ports as closed

Re: Ports 21 and 22 are open but the rest are not.

astronovaval — Thu, 07 Sep 2023 09:34:46 GMT

that makes sense, if the UDP port was open, you would be able to see my server in the game's server list and have anyone connect to it. but you cannot sadly.
the main thing im worried about is the 28083 port still not being open, its a key part of the game that i'd really like to have working.

Assuming that you are not testing like your UDP ones & falling victim to NAT Loopback, then the next step is Wireshark. Is your device on 192.168.1.10 either a Windows or Linux PC? They are the two most common operating systems that support Wireshark. I can analyse the traces for you if required. If you are not familiar with Wireshark, then I can send you a guide of mine on it.

Re: Ports 21 and 22 are open but the rest are not.

astronovaval — Thu, 07 Sep 2023 09:37:47 GMT

Its running Linux Ubuntu currently, and I'm pretty unfamiliar with Wireshark.

edit: ive just installed it on the machine

Re: Ports 21 and 22 are open but the rest are not.

KeithFrench — Thu, 07 Sep 2023 09:45:39 GMT

No problem.

Give me a shortwhile to update my guide on how to install it in Linux & I will send it to you.

KeithFrench — Thu, 07 Sep 2023 10:23:31 GMT

I will PM you shortly.

You do not have PMs enabled currently within your Community Profile, I will ask TalkTalk to enable them for you.
