Hi there.

I'm having a lot of trouble getting ports 27000-27037 open. See attached images.

I am having this trouble.

The game's tech support people told me to make sure I have opened the ports steam recommends me to keep open.

So I tried this

But I still get this message when I test the port! Infuriating.

I'm sure I'm missing something obvious. Can someone please help me out?

Thanks in advance!

I think CanYouSeeMe.org might only check TCP ports, while most of your ports needed are UDP. So not a good test.

I assume your workstation is definitely 192.168.1.2?

Are you using any Antivirus with a built in firewall? If so, try disabling it or a short while.

Got Windows firewall turn on? If so, try disabling it or a short while.

Hi. Thanks for the quick reply.

Any way you'd suggest to test UDP ports?

My desktop is definitely 192.168.1.2. I have it set as a reserved address on the router's DHCP page.

No antivirus with firewall. Windows firewall turned off to try to sort this out.

Cheers.

UDP is connectionless, so not easy to test.

Did you NAT UDP/4380 as well (the last one in the list)?

Hi,

I just added another rule for UDP 4380. Using this port tester each of these rules don't seem to be actually opening the ports. I feel like I must be loading the rules wrong in the router or similar.

I talked to Spark and they said they don't block any ports on their end, which seems unlikely to be true but what do I know.

Cheer.

Does your game support uPNP? If so, I would delete your port forwards and use that instead. Everything is automatic when using uPNP. You could also consider giving your router a reboot in case it has got into a sick state.

Just a quick thought but are you on ADSL or VDSL? If you are on VDSL you have port firwarding the ADSL connection ports on the router. I found that out a while ago with the Huawei that you have to specify the connection for port forwarding.

Firstly UDP is stateless. Secondly uPNP really is your solution, and thirdly doing a port scan like you're doing isn't necessarily going to give the results you think it should. If a stateless UDP port doesn't respond there isn't really any way of a simple test like you're going knowing whether it's open or not.

They block port 25 on some connections as a spam prevention measure, but this should have no impact for you.

As Steve says, try enabling uPNP on the router.

They don't, and there is no reason for any ISP to block any ports other than the port 25 filtering that many may use.

Any chance someone else in your househould is using a Steam game on another machine/device, so that uPNP has already forwarded the ports to their machine, making them unavailable for your machine?

Bang on the money.

Not sure how this worked, but it did. I checked the router for uPNP (it was already on), removed all my port mapping rules, rebooted router and also desktop for good measure, and since then I haven't had a single "Connection Interrupted" error ingame.

Thanks for the help y'all!
