Yes but when I will have many vlans behind the machine and many clients, the natd translation table might get full eventually if I only use 1 external IP address. I want to use same IP address in different VLANs because I have customers with same IP addresses which has seperate gateway machines. I will just combine all the gateway machines in one machine. Thats my plan.
