Short and sweet
have a minecraft server I host myself
if i'm on my network i can play on it, only others can't do it
guess: the router does not want to let others access
how do I change this (have nen cisco router and am with cable Germany / vodafone)
That's called port forwarding…
You have to specify an ext port in the router, which then pointed to your PC (IP / server port). For this, the server needs a fixed IP in the internal network. And your friends will have to specify your ext IP and the ext port you set up.
That's exactly what I've done ha the server has its own IP that is for sure
how else could I access the sevrer from my own
Well, if you host the internal network, you're accessing the internal IP. So 192.168.x. Something. This has nothing to do with the port forwarding.
From Vodafone but you have indeed another IP, which is accessible from the outside. But all requests are blocked. Only when you have set up there the port, and points to the correct IP, and the port belonging to the IP, others come through the router on the internal network.
Have you assigned the fixed IP in the router? So that the server always gets the same address assigned via DHCP? Or you have set the IP firmly in the PC? And what does your port forwarding look like? (Without announcing your public IP here)
The server config YOU have adapted synonymous? That the server ext is reachable?
Bzw, you changed something in the Server.properties? IP can leave you there… Had with me but once stated. But you probably do not have (according to config description)
That made me a friend of mine I can't do anything with debian (server operating system)
how can I get the ip that vodafone gave me?
Either on wieistmeineip.de or look in the router. It has to be somewhere, too
Have my buddy what you said on discord sent
his answer: Yes, this is just a little bit more difficult for you because you have vodafon only ne ipv6 and it runs on two routers
And somehow, one of them does not quite shut the port, even though I did a port release on both
Well, I have a Fritzbox and I'm synonymous with Vodafone. There was no problem so far… But always had an IPv4 address. Mine, I would have that too. But I've set up a DynDNS anyway, which was automatically fed by the router. The then passed on my connection, even if my IP has changed. The router has automatically re-deposited.
Two routers in a row is a challenge…
The first router must then refer to the second, and the second then to the PC, which runs as a server (which should really be connected in series and map two of their own networks… I have not tried yet.
* Sorry for the new answer… Wrong comment field taken… ^^
All right, my son
there's something called that brige mode in the vodafone customer portal
Then all the PC's but the 2nd router hang, because the cable router only assigns an IP and everything 1: 1 to the connected 2nd Routers… But that could possibly solve the problem… Did not know that until now. Well, I have never needed…
So I would have to put my server to the 2 routers?
If you put the cable router in Bridgemode yes. Because then the router can only supply one device. And that would be the 2nd router.
But if your server is already on the first router, you only have to set up the port to the server. The second router then needs no settings, which concerns the server.
That means if I do in the bridge mode on a router which is otherwise useless
No more than router, bridge = bridge, so just loop through what's up. You then no longer have IP administration. And Vodafone manages only one IP per connection. This is then distributed in the router to the underlying network, as the data is requested. In Bridgemode, however, this distribution is disabled and only one device behind it has full access. The rest is empty. This Bridgemode is there for, if one wants to operate the cable modem without routing function, because one has its own completely managed network with own rout behind it. Logically, all network devices then have to hang behind their own router, since only he still distributes and manages the accesses…
