FTP Server Configuration through TMG Edge Firewall

(imported topic written by send304591)

Hello Everyone,

I am having some issues allowing access to my ftp server from outside.

However, accessing from inside network works fine.

I have forefront 2010 edge firewall (My network layout is Internet------->TMG ForeFront------->Windows Web Server 2008R2 - This server has two NICs - one is connected to Inside LAN and another one is connected to TMG network)Network Topology. I run through the setup wizard create new server publishing rule.

I am using the FTP Server protocol

My Firewall Policy (Non-Web Server Publish)

Traffic: FTP Server

From: External

To: Server IP (10.10.10.30)

Selected “Requests appear to come from the Forefront TMG computerâ€

Network: Perimeter

FTP Access Rule

Protocols: FTP

From: External

To: Server Name – (FTP Server IP Address 10.10.10.30)

Users: All Users

FTP Server: Windows Web Server 2008R2

When I try to ftp from LAN it works. However, when I try to ftp from external address I

get following log report in my TMG Logs Report Screen

Denied Connection TMGServer 4/11/20xx 10:26:28 PM

Log type: Firewall service

Status: The policy rules do not allow the user request.

Rule: Default rule

Source: Perimeter (xxx.xx.xxx.xx:2801)

Destination: Local Host (xxx.xx.xx.xx:21)

Protocol: FTP

If you can help me to figure out this problem I would really appreciate.

Thanks and regards,

AJ
