Someone asked me and I realized that I never knew it.

On which port does fortigate start the usage for SNAT ports? I mean, what is the first and last ports usued by fortios on snat port translation?

Thank you all in advance.

i don't know for sure and didnt find a kb or such.

i did check some systems and found some low 10000 ones like 12908. nothing below 10k though. seems like a possible limit there.

@boneyard thank you for the feedback.
