Sorry guys if this has made it before to the list, I just subscribed.
Here is my situation:
ISP Gateway: 111.111.111.253
My gateway : 111.111.111.254
subnets routed from ISP to 111.111.111.254 : 222.222.222.144/29,
333.333.333.192/27 and 444.444.444.128/26
I have three internal networks that I don't want them to see each other
but I want a way of seeing them all: 192.168.3.0/24, 192.168.4.0/24 and
192.168.253.0/24
all these internal networks are running either web, mail or other kind
of services that needs to have one to one nat with a public address.
now I'm running as follows:
first linux box:
eth0: 111.111.111.254
eth1: 222.222.222.145, 333.333.333.193 and 444.444.444.129
no protection at all, don't know how to do it
second liunux box:
eth0: all the above public IP addresses
eth1: 192.168.3.1, 192.168.4.1, 192.168.253.1
shorewall is doing all the natting and dnatting ..etc.
this setup is working fine except not able to protect the first box.
The question is: Is there a way in shorewall setup to do all with one
box, or if not, how to protect the first box and keep the traffic
flowing?
Thanks for any advises in advance.
