NAT problems
Hello,
I've got a problem with my network setup that I can't solve.
It looks like IP tables in kernel 2.4 solves it but I dont have the time
(and courage) to do that right now.
My firewall have these NICs:
eth0 192.168.2.254/24 is connected to my IP-provider using private ip
eth1 a.x.y.z1/27 is connected to my server segment using "real" ip
eth2 a.x.y.z2/27 is connected to my workstation segment using "real" ip
and now I must add a fourth net:
eth3 192.168.10.1/24 ond I want to NAT those adresses when they access
internet (through eth0)
The problem is that when I add the rule for masqurading it translates
all 192.168.10.1/24 to eth0's 192.168.2.254 before routed to my ip
provider, and that adress is a private one and will not work!
How do I solve this in kernel 2.2?
In kernel 2.4 it looks like it's possible to do something like:
iptables -t nat -A POSTROUTING -i eth3 -j SNAT - -to a.x.y.z1
but 2.4 is not an option right now.
Regards
Tobias
