Hi
I have the following setup below. A FreeBSD 4.9
machine with 3 nics fxp0, fxp1 and ed0. Fxp0 is
connected to my DSL connection, fxp1 is connected to
my Cable connection and ed0 is my internal network.
xx.xx.12.1 yy.yy.34.1
--------- ------
| DSL | |Cable|

.12.2 | |.34.2

| FW |
| Default route |
| xx.xx.12.1 |

|ed0
|192.168.200.1

What I'm trying to do:
Need to have inbound web traffic (from both
connections) foward to the same internal web server.
Problem:
When a web connection is made to xx.xx.12.2:80(DSL),
its nated to 192.168.200.10:80(websrv) and then back
to the client(all is well at this point).
The problem occars when a connection is made to
yy.yy.34.2:80(cable), it's nated with the second
instance of nat to 192.168.200.10:80(websrv) but when
it trys to respond back to the client the default
route forces it back thru the first connection.
Does anyone have a good example of a fwd & divert
rules that would help with this issue?
Thanks in advance
Jason Highland
