Hi Peter ,
Can you elaborate a bit more regarding , why i need to be lucky to make this
set-up work?
I have decided to go for 1 IP address per SIPp instance. So as i want to
have 2 SIPp instances , i want to have 2 virtual IP's configure on the
network interface card. This 2 SIPp instances needs to generate 100,000
users each.
As stated in my first mail , i have connected both the PC's with Cat 5
cable. I hope this set-up works.
Btw , how did you solve this issue in your case , as you said being outside
of SIPp.?
Regards ,
Sougata
