Hi,
I'm trying to use Linux as a small router but it is probably not my day :)
this is the configuration I have:
+------+
| O |
+------+
|172.17.2.3
|
|
|172.17.2.30 Masquerade t this interface
+--------------+
| A - Linux |
+--------------+
|172.16.0.1
|
|
+------+172.16.0.2 | 172.16.0.10+------+172.30.0.1 172.30.0.10+------+
| B |--------------------------| C |--------------------------| D |
+------+ 255.255.0.0 +------+ 255.255.0.0 +------+
interface I have:
eth0 Link encap:Ethernet HWaddr 00:E0:72:A0:03:1F
inet addr:172.17.2.30 Bcast:172.17.255.255 Mask:255.255.0.0

inet addr:127.0.0.1 Mask:255.0.0.0
UP LOOPBACK RUNNING MTU:16436 Metric:1
RX packets:283 errors:0 dropped:0 overruns:0 frame:0

collisions:0 txqueuelen:0
RX bytes:82004 (80.0 kiB) TX bytes:82004 (80.0 kiB)
this is the perliminary routing table I had:
Kernel IP routing table
Destination Gateway Genmask Flags MSS Window irtt
Iface
172.16.0.0 0.0.0.0 255.255.0.0 U 40 0 0
eth1
172.17.0.0 0.0.0.0 255.255.0.0 U 40 0 0
eth0
0.0.0.0 172.17.1.10 0.0.0.0 UG 40 0 0
eth0
I add the next route:
route add -net 172.30.0.0 netmask 255.255.0.0 gw 172.16.0.10
so now I have the next routing table:
Kernel IP routing table
Destination Gateway Genmask Flags MSS Window irtt
Iface
172.30.0.0 172.16.0.10 255.255.0.0 UG 40 0 0
eth1
172.16.0.0 0.0.0.0 255.255.0.0 U 40 0 0
eth1
172.17.0.0 0.0.0.0 255.255.0.0 U 40 0 0
eth0
0.0.0.0 172.17.1.10 0.0.0.0 UG 40 0 0
eth0
Connection test using ping:
A --> O : OK
A --> B : OK
A --> C : OK
A --> D : OK
-
B --> A : OK
B --> O : OK
B --> C(172.16.0.10) : OK
B --> C(172.30.0.1) : Fail
B --> D : Fail
1. The default router for B is A.
2. All the stations except A are Win2K/Win9X
Any idea what I should do so that B can get to D?
