GIT Configuration

hello,

i am trying to configure nfsu2 for git. everything works is perfect. i can setup a server. and all other users able to see the server. but when we try to enter the lobby nothing happens. "entering lobby" text stays for long.

i thought something is not working properly so started to log the connections. when i investigate the unforwarded log file i encountered following lines.

Mon Mar 14 23:08:40 2005] network: hw:00:ff:c3:b5:a0:d6 EthernetII IPv4 TCP to:10.8.0.1:1402 from:10.8.0.2:9900 'wrong port number'
[Mon Mar 14 23:08:41 2005] network: hw:00:ff:c2:b5:a0:d6 EthernetII IPv4 TCP to:10.8.0.2:9900 from:10.8.0.1:1402 'destination is unicast'

the machine has 10.8.0.1 numbered ip is server, and 10.8.0.2 numbered is client. when a packet goes from 10.8.0.1 from port 1402 to 10.8.0.2 port 9900 it produces destination is unicast error. i know that 9900 is the port need for speed used on lobby connections. so that explains why we lock while entering the lobby screen. does anyone know how i solve this problem???

It should be quite clear that you have the option checked that is called "Don't forward unicast" and you also are not forwarding port 9900 it looks like.
These are not errors, just indications of what traffic you are or are not forwarding. Of course, check the date stamp - Mar 14, if you changed options since then, you may want to delete GIT's logs and start over.

Thanks ark i have unchecked the option you have told but this time i receive following lines on unforwarded log file

Mon Mar 20 21:08:40 2005] network: hw:00:ff:c3:b5:a0:d6 EthernetII IPv4 TCP to:10.8.0.1:213 from:10.8.0.2:213 'wrong port number'
Mon Mar 20 21:08:40 2005] network: hw:00:ff:c3:b5:a0:d6 EthernetII IPv4 TCP to:10.8.0.2:213 from:10.8.0.1:213 'wrong port number'

What shall i do for this case????

Is there any wizard git file which will make my life easier for NFSU2 game??????

You should probably ignore, or not log that, unless you intend to create an infinite loop of tunneling GITs own traffic from por 213.

This occurs when i try to connect the lobby on NFSU2 game. Both server and client is capable of seeng themselves. Server can connect the game lobby but client cannot.

That could be ignorable but in that case GIT is not working. Something could be wrong on the configurations. Let me ask my question from another viewpoint. What could be the configuration for following environment.

2 machines connected with OpenVPN (Client and Server able to ping each other)
Server has ip of 10.8.0.1
Client has ip of 10.8.0.2
For connecting, forwarded port could be 9999 for broadcasting, 9900 for connection.

My configurations,
10.8.0.1 is forwarded to 10.8.0.2 over port 213 using UDP layer. 10.8.0.2 is forwarded to 10.8.0.1 over port 213 using UDP layer.
9900 and 9999 numbered ports are forwarded
Ethernet II, Forward ARP, ZLib Compression,TCP,UDP,ICMP, Don't Send Routable and Also Match Source Port options are selected.

Assuming the client and server have the same subnet mask and no other computers on either side are conflicting with any IPs between the two networks in the 10.8.0.x range - are you sure the game only needs port 9999 and 9900? Are you sure VPN is not conflicting by also forwarding ports? You absolutely do not need VPN for what GIT can do. Perhaps the VPN is sending GITs traffic on port 213 as well and causing duplicate packets. The first thing I would try is to just get rid of the VPN.

hello ark,

i have tried to forward all ports between 241-65535. not only 9999 and 9900 so that didn't work either.

i will check it again but i initiate vpn only between two computers so it is not possible to have ip confliction.

i would like not to use vpn but i am connecting internet over ADSL. In advanced configuration tab "Look at which frames on which device" combobox i cannot see my DSL device, truly it should not be there caus it is not ethernet adapter ;). in that case i am to use vpn...

From your reply you did not suspected if the configuration is true. That shows you think everything seems correct on configuration side. Maybe my vpn causes interruption (or whatever it is called).

Let me check the which ports vpn is using. Is there any other way to make git work with ADSL type connection...

There are several ways to get GIT to be able to see packets on your ADSL modem. The best is to simply actually use an ethernet card, and not use any PPPoE software. Have a physical ADSL router/modem combo handle the PPPoE, it will be a lot less headaches in general for your internet connection that way. Most new ADSL installs tend to give out router/modem combos that work just like cable modems (cable or phone in, 1 port ethernet out). Some of those that support ethernet also have a USB port, and if you use that instead of the ethernet port, you are just making things more difficult in general for internet related things.

Another method is to install a virtual network adapter, which there are several threads about already here. This is basically what a VPN does, on top of other things. Virtual network adapters are supported by Windows 2000 and Windows XP without any 3rd party software, you can just go install them as a network device, but you still need to configure them manually (enter your 10.x.x.x IP, etc). You don't need or want to configure a virtual adapter with the same IPs as your actual ADSL modem. You just make up an IP range and use it (well, pick from the reserverd ones 10.x.x.x or 192.168.x.x or 172.16-31.x.x)

yes ark the second thing is actually what i did. i have my vpn worked. but still got the same lines on unforwarded log file

Mon Mar 20 21:08:40 2005] network: hw:00:ff:c3:b5:a0:d6 EthernetII IPv4 TCP to:10.8.0.1:213 from:10.8.0.2:213 'wrong port number'
Mon Mar 20 21:08:40 2005] network: hw:00:ff:c3:b5:a0:d6 EthernetII IPv4 TCP to:10.8.0.2:213 from:10.8.0.1:213 'wrong port number'

what may cause for that...

Again, the cause for anything that shows up in unforwarded.log is that you did not set the options to forward that traffic. All network traffic is either going to show up in forwarded.log or unforwarded.log, depending on what you want to forward and what options you set. Please stop thinking it is an "error" or something.

i dont think it is error. but i think it is something that prevents some network packets to be distributed between machines. so which options shall i check or remove to make things work

my configurations
2 machines connected with OpenVPN (Client and Server able to ping each other)
Server has ip of 10.8.0.1
Client has ip of 10.8.0.2

10.8.0.1 is forwarded to 10.8.0.2 over port 213 using UDP layer. 10.8.0.2 is forwarded to 10.8.0.1 over port 213 using UDP layer.
9900 and 9999 numbered ports are forwarded
Ethernet II, Forward ARP, ZLib Compression,TCP,UDP,ICMP, Don't Send Routable and Also Match Source Port options are selected.

i would like to indicate that i am trying to play need for speed underground 2
