I need some help.
I have a freebsd 5.0 box running IPNAT and IPF as a firewall. I currently have five
static IPS with my ISP. With my ISP I must register the MAC address of the adapter to
obtain an IP. Thus I have a FreeBSD box with six nics in it ( all 3c905C).
The basic config is as follows:
*****************************
* *
* Internet *
******************************
|
|
|
3Com DSL Bridge
|
|
|
3Com 10MB Office Connect Hub
| | | | |
| | | | |
| | | | |
| | | | |
| | | | |
xl1 xl2 xl3 xl4 xl5
********************************************************
* *
* FreeBSD 5.0 IPNAT/IPFW *
*********************************************************
|
|
|
xl0
|
|
3Com 3300 XM Switch
I can get one external NIC up and running. But when I get a second one up and running
I get a kernel message stating
that the second NIC (xl2) is trying to use the same IP as XL1. They are set to
different IP's in the rc.conf. I assume that this is because they can see each other
on the hub that splits the 3Com bridge out.
Is there any arguments or settings that I could use to resolve this? An ipconfig
setting? Or even a kernel option. I would recompile the kernel in a second if it would
help.
You can assume that xl1 has an ip of 142.179.196.134 and xl2 has an ip of
142.179.196.135 both with a subnet of 255.255.248.0.
Thanks in advance
