The network guy tells me that the sonicwall is set up to not allow pinging so I can't test it that way. I'm with you bacherjr, if he really has 1:1 nat set up the sonicwall shouldn't care what ports the samsung wants to use. One more question, since we are trying to use 1:1 nat, with the sonicwall forwarding a public address to a private address, should I set up mmc's 830 and 831 with the public address the same as the private address, and public w/private turned on or something else?
