Hi,
I have a routing problem that I want to share with you people ;)
My situation is as follows:=20
Workstation
|
Server
| |
ppp0 ppp1
As you see, i have 2 internet connections. One of them (ppp1) is dedi=
cated to some gameservers I am running. To make sure all incoming tra=
fic on this interface also leaves via this interface, I added the fol=
lowing rules:
from all to 145.y.y.y lookup ppp1
from 145.y.y.y lookup ppp1
And table ppp1 contains the following entries:
145.y.y.y dev ppp1 scope link
default via 145.y.y.0 dev ppp1
It is clear that when I connect from my Workstation to a gameserver r=
unning on ppp1, I will never receive any packets, that's why I have a=
lso added the following rules:
from 145.y.y.y to 192.168.0.0/16 lookup main
from 192.168.0.0/16 to 145.y.y.y lookup main
So this is all working well, but here comes the problem. The gameserv=
ers are communicating with some master servers to authenticate my cdk=
ey. The client (my workstation) sends a message to the master which c=
hecks my cdkey and stores the result of that with my ip. When I conne=
ct to a gameserver, the server connects also to that master and asks =
if the player has a valid cdkey by sending the players IP address. An=
d there is the problem. Because I am connecting from a LAN behind my =
server, the gameservers which runs on my server see me with a 192.168=
.x.x address, but the master server is seeing my public IP address (p=
pp0). As you understand, because of this it is impossible for me to l=
ogon on my gameservers :(
What I have tried to do, is to route traffic coming from my Workstati=
on with destination ppp1 over ppp0 to the gateway. Then the gateway w=
ould send the traffic back to ppp1 and both the master and my gameser=
vers see my public IP address. This is what I have done:
The rule
"from 192.168.0.0/16 to 145.y.y.y lookup main"
changed in
"from 192.168.0.0/16 to 145.y.y.y lookup ppp0"
and I deleted the rule
"from 145.y.y.y to 192.168.0.0/16 lookup main"
table ppp0 looks like this:
145.x.x.x dev ppp0 scope link
145.y.y.y via 145.x.x.0 dev ppp0
Unfortunately this aint working, but what am I doing wrong? Is it jus=
t impossible for a server to route traffic, with destination a interf=
ace on the server itself, to a gateway? If so, do you maybe have anot=
her idea on how I could solve this problem?=20
Thanks in advance,
Pim
