FTPS and Sonicwall
![Paul_Celin75](https://us.v-cdn.net/6031761/uploads/defaultavatar/n29VP08P5C5ND.jpg)
Hello,
I setup a rule to connect to a ftps server outside of my custommer network and I keep receiving the following error message:
TCP FIN packet dropped, out-of-oder command packed dropped
My rule is as followed:
WAN To Lan, only the the IP address of the ftps server is allowed to communicate through some ports (submitted by the FTPS server host) to computer.
Any help from you will be appreciated.
Thanks in advance.
Paul.

Hello @Paul_Celin75,
Welcome to SonicWall Community.
So, the FTPS server is behind the SonicWall and a computer from outside is unable to talk to it?
Could you please make sure that the port forwarding is done correctly as per the KB article below
Also, the packet that is being dropped, is it the SYN packet or just some other packet? Also, are you able to successfully connect to the FTPS server internally?
Is the connection made in active or passive mode?
Thanks!

Hello @SHIPRASAHU93,
Thanks for your prompt reply.
The server FTPS is outside of the sonicwall network. The computer we are using to access it is behind the sonicwall. The connexion is made in passive mode.
Thanks again.

Hello @Paul_Celin75,
In that case the Any, Any, Any LAN to WAN rule should allow this traffic.
Thanks!

Hi @SHIPRASAHU93,
I added the ports range used by the ftps server in the access rules from LAN to WAN.
Thanks.
