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.=20 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.
