We are running Open BSD 3.8 as a firewall router. The router has two
internal networks to handle; a DMZ with "real"
ip adresses and a NAT network to which our workstations are connected.
The problem I have is that its not possible to
connect to the server on the DMZ (ip 22.214.171.124, netmask
255.255.255.252) from the outside (but from the inside).
I guess that I somehow has to make the external interface listen to the
same adress as the server (they are on the same net), but if I add
an alias to the external interface it doesn't (of course) route packages
to the DMZ. How do I make OpenBSD route packages to the server
(and the DMZ subnet)?
Our ISP has given us a net that has the following data:
Net segment: 126.96.36.199 /28
net address: 188.8.131.52
gw address: 184.108.40.206
free ip ip: 220.127.116.11-126
broadcast address: 18.104.22.168
the server has the following interfaces configured:
### interfaces ####
inet 22.214.171.124 255.255.255.240 NONE
inet 192.168.97.254 255.255.255.0 NONE
inet 126.96.36.199 255.255.255.252 NONE
Thanks in advance
