    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.
