I am probably missing something very simple , but after much Coke and snacks
I cannot figure this out.
System : FreeBSD 4.5 Stable
xl1 xl2 xl3 xl4

xl0
(Internal Nic) 10.0.11.x 255.255.255.0
Ok , this FreeBSD bx has been working like a charm doing NAT from the
internal net to the external (using xl1). I installed the xl2,xl3, and xl4
nics with the following objectives. I want to redirect ports or addresses( I
cannot get any ot them to work) from the external interfaces ( ie xl2) to an
IP on the internal network ( say 10.0.11.253).
Questions
1) Can I define multiple interfaces in the natd.conf file? ( ie interface
xl1 xl2 xl3) What is the format?
2) Do I define the redirect_port/redirect_address in the natd? ( I assume
so) and in the firewall script( /sbin/ipfw add fwd tcp (external) from any
to (internal)
(If you have a simple natd.conf and firewall script that you know works with
port/address forwarding that would be great)
I simply want to get packets from an external NIC , forwarded to an internal
IP with responses forwarded back thru the external NIC. One real example is
the need to get VNC ( ports 5900-5902) from a external IP to connect to an
internal machine , and have that internal machines packets routed so that
the VNC session works.
Any help is greatly appreciated.
