Re: [FW-1] FW1 v4.1 on NT 4, Single external IP
Yes in the followin configuration:
Internet 129.1.1.1

.

/ FW-1 \

+-----------+
| 192.168.1.1
| 192.168.1.2
+-----------+
| Router |
+-----------+
| 10.1.1.1

FTP HTTP servers
10.1.1.2 10.1.1.3
You do a route add -p 129.1.1.1 mask 255.255.255.255 192.168.1.2
and the router will dispatch it to 10.1.1.2 or 10.1.1.3 because the
FW-1 send the packet to 10.1.1.2 or 10.1.3 depending on port (21 or 80)
NO in the followin configuration:
Internet 129.1.1.1

It's because you need to use the Windows NT routing and you can't use the
following syntax:
route add -p 129.1.1.1:21 mask 255.255.255.255 10.1.1.2
route add -p 129.1.1.1:80 mask 255.255.255.255 10.1.1.3
You can route on a port basic, just IP address basic...
