Windows 2003 Server VPN w/GIT help game broadasting

Postby fettabob » Tue Mar 22, 2005 6:46 pm

Ok my friend and I have used VPN w/XP to my 2003 server for awhile now but the problem we have is that games that need for him to see the broadcast of the server in the lobby never happens. He usually plugs in the LAN ip address of the game server in the internet connection. Some games dont have this option. How can I setup GIT with
2003 Server VPN + XP vpn client

Me Internet - Linksys - 2003 Server - Hosted PC w/game -

him - Internet - Linksys - VPN XP client - Game that needs to see LAN broadcast on my side

any suggestions?

GIT does not need VPN to work, in fact, you are just asking for trouble making things more complicated by even using VPN. Disable VPN and use just GIT and it will probably be easier to configure GIT and get it working.

So now Im a little confused. I use VPN so I dont have to open a ton of ports on my linksys. So the question is if I use GIT and no VPN do I have to open a different port?

You can use GIT to create a virtual network (its not private, there is no encryption). You only need to open port 213 on your router, nothing else. As long as you set up both physical networks to be on the same virtual network with out any IP address conflicts, it will be as if the two networks are one.

so my lan ip internal is 223.140.1.xxx
his is 192.168.1.xxx

he or I would have to change our internal setup to match up? Also one of us after that would have to change our router ip from say mine is
223.140.1.1 to 223.140.1.2 or his change to another one besides my gw then correct?

Well you would have to both use 192.168.1.x because 223.140.1.x is not a reserved private IP range, in fact, I don't think its a valid range at all, its still reverved by the IANA for future use. So it doesn't seem as if you are using NAT, even though you might be.
Ther is no rule saying your router/gateway IP has to end with .1 Some ISPs commonly set the gateway to .254, so it is no big deal to change it.

Ok I changed my side to be 192.168.1.1 for the router. his is 192.168.1.3
for the router. He seems to be connected but I cannot ping him nor can he ping me. MS XP firewall is off
Ideas?

Ideas? how about: More information?
Is ICMP being forwarded?
Is ARP being forwarded
Are there other IP address conflicts between any device on either side?
Are you using the same subnet?
Are you connecting using port 213 UDP on each side?
Is port 213 UDP forwarded from the external IP to the computer running GIT?
Are you using the alter source IP option? You shouldn't be.
Are you forwarding unicast traffic?

The generic TCP/UDP wizard will help you get started for this type of virtual nonprivate network setup.

Ok
ICMP forwarded is checked
ARP
all ips are accounted for on both sides (ran a ip scan on both sides and found no conflicts
and both are 192.168.1.xxx
my router lan 192.168.1.1
his router lan 192.168.1.3
sub is 255.255.255.0 on both
we both are forwarding 214 on both sides
and not using source ip option
and unicast dont forward is unchecked.
also any diff if he has a linksys WRT54G and I have a RV082 linksys?
