The Graveyard - Products No Longer Supported > DIR-655

dir-655 allowing game traffic when it should not be doing so

TQuach:
I agree with Master Hamster.  Kinda what I was trying to get to.. good wording.

buach:
that is not the setup i am accustomed to from past routers.

to use vnc - even when the connection is initiated by me, i had to open port 5900.

to use bit torrent you need to open ports (although i think this is a listening port so the connection is initiated by others (incoming in other words).

and far cry has never worked for me on any other router without me opening the correct ports.

Fatman:
To use a VNC client requires no ports opened.

Bittorrent is a bit of an odd ball as everyone is a server.

I know not of Far Cry.  I however checked Ubisoft's FAQ on the issue which claims you need ports to run the client.

It also mentions that the ports are usually opened up by the OS, sounds like they implement UPnP on the game itself to me.

And if I am not mistaken you do not need to have UPnP enabled in Windows to enable software to open up ports with it, at least if I was writing the software I would just send the requests regardless of whether the computer is seen as a active UPnP host or not.

Is UPnP disabled in your router as well as Windows?

yes upnp is definitely disabled in the router and windows. I have never liked upnp.

i see you are from dlink so i'd like to ask you this. is the dir-655 meant to allow all traffic / packets that are initiated by the local machine to get out to the net (of course i understand that once this initial request has been made the router will allow the returning packets through). is it behaving as its meant to when it allows far cry access to the net on these ports without me having to open them first??? if you could give me a definitive answer on this it would be helpful.

my previous experience of routers is that on non standard ports, even if the connection is initiated on the local machine, the router stops them getting to the net until you open the ports.

Just in case it is of interest, here is a list pasted from internet sessions while far cry multiplayer is running (these are all correct far cry ports).

Fatman:
Yes all traffic outbound of the router is supposed to be allowed by default.  The problem is that in most games the server or other player you are connecting to will then try to contact you over a different and unrelated port, this is why port forwards are necessary for some games.  However it looks like the required ports (assuming the log above allows you to get online perfectly) are all outbound.
