Standard FTP in private network

Hi!

I'm trying to config ASL 3.202 so that I can run a FTP server in my private network to be accessable from the "outside".

FTP server IP:   192.168.1.1
ASL internal IP: 192.168.1.254
ASL external IP: 130.83.19.167
masq private LAN on WAN-Interface

First I added a packet filter rule:
All/All -> WAN_Interface/FTP : allow

Then I added a S-/DNAT rule:
All -> WAN_Interface SRCTransl.:none DSTTransl.: FTPserverIP

But (as I assuemed) I doesn't work.   [:(]
Do I have to allow FTP-Control separatley and add another S-/DNAT Rule?   [:S]

Tkx in advance.
Greetings
Chris

your packet filter rule is wrong, it has to be Any->ftp->FTP Server->allow, DNAT is done before the packet filtering, the packet filter sees the translated address.

check the default gateway of the ftp server, has to be the internal interface of the Astaro.

The GW is configured correctly.

f3@Rl3SS,

what is being filtered!

Hmmmm ...
none of the FTP connections I tried to establish are filteres. So ... packet filtering seems to work correctly ...

Hi,

u set:
Then I added a S-/DNAT rule:
All -> WAN_Interface SRCTransl.:none DSTTransl.: FTPserverIP

I think, this is wrong!? try this: S/DNAT 2FTP

match parameters | src trans | dst trans
any --> WAN_Interface_/FTP --> none ----> ftpserver

rule filter must set to
any | ftp | ftpserver | allow

it runs!(?)
bye

I allready noticed that failure and fixed it. But it still does not work. [:(]

PS: I got the same problem with all forwarded ports. UT Server, CUSeeMe, etc. ...

Try setting a NAT rule ANY/ANY > ftp server IP
Try setting packet rule for ANY packets to anywhere to go through.

People should use PASV mode to connect to the ftpd.

It should work, I've set this up, I'd show you the config but our ISP for that box just collapsed !
