CBAC with FTP on a different port

I have successfully configured ftp on the default port with an inbound acl for a specified range of ports for passive ftp.

So the acl look like this

permit tcp any any eq 21

permit tcp any gt 1023 any range 61000 62500

i then tried to change the ftp port to 35000 by configuring " ip port-map ftp port tcp 35000 and then changed the acl to allow port 35000 inbound.

That doesn't work as the passive port range gets denied inbound for some reason. Has anybody else got ftp to work on a different port?

Hi .. have you tried without specifying TCP .. also just for testing allow any inbound to that port just to make sure the mapping is actually hapenning ..

permit tcp any any eq ftp

ip port-map ftp port 35000

Yes, it converts it if you don't specify.
