-t nat -A PREROUTING
You forgot "nat" after -t. Is that a typo or is this the actual rule you
are using ?

You just added a PREROUTING rule, and now you're checking if a POSTROUTING
rule is correct...
Furthermore : POSTROUTING doesn't have DNAT (it has SNAT) so the result of
"iptables -t nat -L" are probably not copy-and-pasted.

Again : -t nat

Don't know if it will solve your problem but :
- use "-t nat", not just "-t"
- check the chain you're adding a rule to (if it's PREROUTING, check
PREROUTING, not POSTROUTING)
