Hello,
i have had a terribe day today, why? because i have been so 4 or 5
hours trying to do work this and i have not finished it. I feel very
pleased if anything can help me. I have two isp connections:
eth0:
dhcp
ip1: 82.198.*.*
gw1: 82.198.*.*
and a router adsl in ip 192.168.0.253:
eth1:
static
ip2: 192.168.0.254
gw1: 192.168.0.253
the same machine has 3 more networks cards but i am using only 4 at this
time:
eth0: internet connection 1
eth1: network range 1 (192.168.0.0/24) and adsl internet connection 2
eth2: network range 2 (192.168.2.0/24)
eth3: network range 3 (192.168.3.0/24)
well i have created two tables in rt_tables like this:
----------------------
#
# reserved values
#
255 local
254 main
253 default
0 unspec
#
# local
#
#1 inr.ruhep
200 aulas
201 oficinas
---------------------
and i have been trying to route from source to any or another table.
ip rule add from 192.168.2.0/24 table aulas
ip rule add from 192.168.3.0/24 table aulas
ip route add default via 192.168.0.253 dev eth1 table aulas
ip route add 192.168.0.0/24 dev eth1 proto kernel scope link src
192.168.0.254 table aulas
ip route add 192.168.2.0/24 dev eth2 proto kernel scope link src
192.168.2.254 table aulas
ip route add 192.168.3.0/24 dev eth3 proto kernel scope link src
192.168.3.254 table aulas
ip rule add fwmark 4 table aulas (this is for dport 80 marked with
iptables go from adsl too)
#oficinas
ip rule add from 192.168.0.0/24 table oficinas
ip route add default via 82.198.*.* dev eth0 table oficinas
ip route add 192.168.0.0/24 dev eth1 proto kernel scope link src
192.168.0.254 table oficinas
ip route add 192.168.2.0/24 dev eth2 proto kernel scope link src
192.168.2.254 table oficinas
ip route add 192.168.3.0/24 dev eth3 proto kernel scope link src
192.168.3.254 table oficinas
ip route add 82.198.*.*/25 dev eth0 proto kernel scope link src
82.198.*.* table oficinas
$IPTABLES -t nat -A POSTROUTING -s 192.168.0.0/24 -d ! 192.168.0.0/16 -j
MASQUERADE
$IPTABLES -t nat -A POSTROUTING -s 192.168.2.0/24 -d ! 192.168.0.0/16 -j
MASQUERADE
$IPTABLES -t nat -A POSTROUTING -s 192.168.3.0/24 -d ! 192.168.0.0/16 -j
MASQUERADE
well i know the iptables can become more specific with snat but i have
tried too. The rules works because if i delete the local range routes i
havent get response from lan packets too so it is classified correctly
but only works the gateway that its in default route in the main table,
if i delete the default main no one range works, if i use the eth0
default only table oficinas works and if i use default eth1 only aulas
table works. I have tried with nexthop adding the two gateways in
default but it doesnt works well either. Can anyone help me please?
Software Versions:
Distro: Debian Testing
Kernel: 2.4.32
iptables: 2.3.3
iproute2-ss051007
Thanks in advance.
