Substitute digits (0-9) for the letters to make the following addition true.

MAINTAIN + INTERNET = FIREWALL

Replace the letters with the appropriate number to make the addition work. Keep in mind that neither the first or last number of each word is a 0 (zero) and if x=4 then all x's are 4 and so on.
