Hello,
I have a Debian-Woody-3.0 Router with 3 NIC's.
Kernelversion 2.4.18
+------------+ +-------------+
| | | |
|192.168.1.1 | | 192.168.2.1 |
| DSL-Router | | ISDN-Router |
+------------+ +-------------+
| |
| |
+---------+ +----------+
| |
| |
+----------------------------------+
| eth0 eth2 |
| Debian-Woody |
| eth1 |
+----------------------------------+
|
|
+----------------+
| 192.168.3.0/24 |
| localnet |
+----------------+
Mail-Traffic over ISDN-Router
WWW-Traffic over DSL-Router
But why?
### Here are my interfaces:
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet static
address 192.168.1.10
netmask 255.255.255.0
network 192.168.1.0
broadcast 192.168.1.255
gateway 192.168.1.1
auto eth1
iface eth1 inet static
address 192.168.2.20
netmask 255.255.255.0
network 192.168.2.0
broadcast 192.168.2.255
# gateway 192.168.2.1
auto eth2
iface eth2 inet static
address 192.168.3.30
netmask 255.255.255.0
network 192.168.3.0
broadcast 192.168.3.255
# gateway 192.168.3.1
Is this correct?
### my route:
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use
Iface
192.168.3.0 0.0.0.0 255.255.255.0 U 0 0 0 eth2
192.168.2.0 0.0.0.0 255.255.255.0 U 0 0 0 eth1
192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0
0.0.0.0 192.168.1.1 0.0.0.0 UG 0 0 0 eth0
and now my firewall-script:
#!bin/bash
# firewall-script
echo 1 > /proc/sys/net/ipv4/ip_forward
?????????????????????????????????????????
iptables -t nat -A POSTROUTING -j SNAT --to 192.168.1.10
so can I surf and get mail, but over eth0
Have anyone an idea?
Kernelmodules are loaded.
