Open port a on Sagem f@st 3504?

[wilbefast]

Euh

I've been having problems hosting games, in the sense that I can only do it through relays. Recently a player said "nub host hasn't opened port" before leaving in a huff, so I've been trying to figure out what they meant. I found myself here:

http://springrts.com/wiki/Getting_Started

Only the page you're suggested to check doesn't have my router on it, so it doesn't really help. The router I have is a Sagem f@st 3504.

Before I go any further, can anyone explain to me a bit more about how one opens a port, and the risks of doing so (it's closed for a reason...).

I'm using Ubuntu 9.10 64 bit, not that that has anything to do with the router's ports... or does it

Missed that.

Is it that different from the other routers of the same brand that are listed on that page? Is it really that far a leap from common sense to click on a couple of links and enter a couple of numbers into its web interface?

Oh, and the risks of opening a single udp port which is used for only one particular piece of software on your system are negligible.

When I'm fiddling with things I don't understand I prefer to follow a tutorial/manual for software/hardware I actually have, especially if it concerns security or my connection - if I break the internet how will I get help fixing it
Also since Spring isn't on the lists either, that means I'm following instructions for hardware I don't have, for software I don't have

Humour me, I've never done this before...

Luckily the router's IP address is written on its underside, so I connected to it, went into LAN servers and added a new entry:



Not entirely sure what do to next though... I'm thinking port 8245 is going to be somewhere, but is that to or from... and the name doesn't make any difference apparently: should I put "spring"?

[Peet]

Server name is just a mnemonic for you. From and to ports are usually the same unless you already know why you want them to be different; so set them both to 8452. Protocol is UDP. Local IP is the ip of the computer you want to host spring from - if your PC is getting its IP via DHCP you will probably want to add a static entry in your router's DHCP server configuration or set it manually from the pc with ifconfig.

What peet said.

I've never heard of sagem, that's interesting.

[wilbefast]

I think they may be French: got it went I signed up with "Numericable".

Right, so the only difficulty is the static IP address... should be able to figure through google and common sense. Thanks for the help Peet :)

[Forboding Angel]

Noeeee!!!

Your local IP.

I have no idea how to access ipconfig on linux, but however you do it, that's what you should do. Also, simply turning of DHCP in your linux box should to the trick of getting a static local IP (depending on your router, you'll get away with this). If DHCP gripes, use a stupidly high or low number from the router.

For example, if your router Ip is:
192.168.1.1

Then set your static as something like 192.168.1.225

and vice versa if your router's IP is high.

The reason for doing that is so that your router has a very small chance of attempting to reassign your static IP. I've seen it happen. A lot of routers only have the option of DHCP on/off, and not an option of giving a single box a static address.

[wilbefast]

There's only one button in Lan Setup & DHCP, and it's marked "stop" - so I'll hit that and then put ~ 192.168.1.1 in Local IP Address in the other window

Don't have time to test it today unfortunately

[wilbefast]

Well, it didn't work



Then my internet suddenly went down and couldn't be revived, I tried everything to no avail, couldn't even connect to the router to reset the settings, resetting the setting manually didn't seem to work either and the tech support people wouldn't help me because I wasn't using Windows. I was this close to reinstalling XP in order to fix the connection!

Then I tried a different ethernet cable

[Peet]

You need to forward the port to your PC's ip address, not the router's local ip.

[wilbefast]

The router's IP is 192.168.1.254 - following what Forb said though I think I may have misunderstood. I thought I was setting a static IP address that needs to be done elsewhere?

Erk - I reckon relay servers might be a better idea

[Forboding Angel]

Oh lol... No, you have to turn off DHCP in your OS, give it a dns server to point to, specify an IP for your computer, etc. Most routers will let you do this and not complain (except my pos trendnet of course... Wish the damn thing would die so I could get one of the new N netgear routers.... those things are sex). My belkin however accepts it with a smile .

TBH just point the IP towards your computer's current local IP address and look for "Lease Time" in your router and set it to some setting that is ridiculously high (this is what I have done... lease time 1 year). That way, it will always try to assign the same IP to your computer (This is probably the less confusing method that works fairly well).
