You'd have to check whether the vendor you're using to NAT SCTP supports
NAT'ing of SCTP.

SCTP NAT is not handled the same way normal PAT- or NAPT-based NAT'ing
is done.

See here for more details:

If your vendor has not hacked their SCTP implementation to support NAT
for SCTP, then you'd need to try another vendor that might have.
