Dear all,
I am trying to setup three PCs and do some simple filter+nat jobs. I'm a
green hand on netfilter and linux and seem to always get something wrong. I
apologize that my current problem has not reached the range of netfilter;
instead, it's about network configuration. But I believe people on this list
are very experienced on it. The situation is specified below:
1.PC1 has one NIC with a global IP connected to a Switch;
2.PC2 has two NICs, eth0 with a global IP connected to the Switch and eth1
with an internal IP (192.168.0.1/24) directly connected to PC3's eth1;
3.PC3 has two NICs, eth0 with a global IP connected to the Switch and eth1
with an internal IP (192.168.0.2/24) directly connected to PC2's eth1.
Internet
| +--------+----+
+------+<-->+PC2/eth0|eth1+
+--------+ + + +--------+--+-+
+PC1/eth0+<-->+Switch+ |
+--------+ + + +--------+--+-+
+------+<-->+PC3/eth0|eth1+
+--------+----+
I am trying to send packets from PC1 to PC3, via PC1/eth0(global
IP)-->PC2/eth0(global IP)-->PC2/eth1(192.168.0.1)-->PC3/eth1(192.168.0.2).
Actually, PC3/eth0 is not in used in the case.
Problems:
Currently I fail to ping from PC3 to PC2/eth1(192.168.0.1). Actually I don't
know which NIC PC3 is using to send the ping packets. I try disconnecting
PC3/eth0, but it still does not work. Could anyone throw some light on it
and warn me what I should pay attention to? Many many thanks!
Regards,
Jee
