I have a question about IP translation. Suppose that I have 6 machines and each machine have about twenty touch panels (Proface) which have assigned IP adress. Unfortunately (made by manufacturer) on each line touch panels have the same IP adresses. I am not allowed to change IP adresses and network mask.
(Touch panel 1) 172.28.3.1
(Touch panel 2) 172.28.4.1
(Touch panel 1) 172.28.3.1 --> 172.29.3.1
(Touch panel 2) 172.28.4.1 --> 172.29.3.1
(Touch panel 1) 172.28.3.1 --> 172.30.3.1
(Touch panel 1) 172.28.4.1 --> 172.30.4.1
To each port of router I will connect switch which connects one machine line.
Is it possible to set it up by static NAT on one router? What kind of router can do it? Thank you in advance for helping me.
As far as the device type - depending on the number of ports you want, a good Cat switch should do it - something like a 3560X or maybe even a 2960, but you may need to go to a 4000 series to get the features - you'd need at least IP Base featureset, maybe even Enterprise to get the NAT stuff you want.
Contact Cisco (your account manager if you've got one) for recommendations as to switch type.
We are pleased to announce availability of Beta software for 16.6.3. 16.6.3 will be the second rebuild on the 16.6 release train targeted towards Catalyst 9500/9400/9300/3850/3650 switching platforms. We are looking for early feedback from custome...
