Problems connecting to FTP sites, with or without fixup protocol

Hi

Im experiencing 2 diffrent problems with 2 diffrent ftp sites.

Scenario 1 - Only works without fixup protocol:

When trying to connect to: ftp-milton.ansys.com (unknown ftp server) im not getting further than to the ftp client is connected (not getting to login/pass), its the same whether its with active or passive mode, as soon as I remove the fixup protocol on ftp on the Cisco Pix 515, the ftp connection works fine.

Scernario 2 - Only works with fixup protocol:

When trying to connect to ftp.intercreation.dk (220 ProFTPD 1.2.10 Server) it works fine thru ftp client, and IE browser thru Windows XP, when trying to save or open files thru Microsoft Word 2003 (ftp option thru Word), the program hangs, and is not able to establish connection to the ftp. As soon as i put the fixup protocol ftp 21 on again, the site works. Its the same on this site, whether its active or passive mode.

So now the big problem is, im only able to get 1 of the 2 ftp sites to work at the time.. - does anyone have any solution for this ??

Here is my pix configuration:

PIX Version 6.3(5)

interface ethernet0 auto

interface ethernet1 auto

interface ethernet2 auto

interface ethernet2 vlan10 logical

interface ethernet2 vlan40 logical

nameif ethernet0 outside security0

nameif ethernet1 inside security100

nameif ethernet2 dmz-int security9

hi

Seen a similar issue here would suggest to try adding this and check for the FTP connections..

access-list inside_access_in permit tcp any any eq ftp

access-list inside_access_in permit tcp any any eq ftp-data

access-list inside_access_in permit tcp any any gt 1024
