I am the system administrator of this small company with 40 users. We
host our own email and web server. I only have a basic understanding
We currently use a 3com Officeconnect firewall, and I want to give the
monowall a spin, and hopefully switch to it.
My company has two ip addresses ranges from our ISP, 126.96.36.199 to
188.8.131.52 and 184.108.40.206 to 220.127.116.11.
Currently, our router has ip 18.104.22.168 and the WAN interface of
our 3com firewall has the address 22.214.171.124
The LAN interface has the ip 126.96.36.199.
The DHCP server on our LAN gives out ips in the range 188.8.131.52 to
184.108.40.206, with netmask 255.255.255.0 instead of 255.255.255.240,
excluding the actual public ips given to us by the ISP. Our email
server and our web server are given these ips.
now, when I set up the 3com firewall, I set it up to have a 1:1 NAT
from 220.127.116.11(16) -> 18.104.22.168(16)
However, when I tried the same thing on monowall it does not seem to
work. What am i doing wrong?
Do I have to configure a static route? Can this be done with 1:1
NATing the entire range of ips that i have been given, like I did with
the 3com firewall?
Thanks for your responses in advance.
