2 ethernet controller on the same network

[krissprolls]

Hi all !

This year, i use two ethernet controller on the same network for the first time,

The only settings that is possible to ajust is the ip adress, subnet and mask.

However, the two controller have in factory config the same mac adress, and multicast ip.

So, it's impossible to connect the two controller at the same time in the show (access problem) even if the ip / mac / milticast adress is different. "Cannot open "ipcard"

I do something wrong or it's impossible to add multiple ethernet controller ?

Thanks in advance

Chris
