How to configure FVS318N to transmit NAT'ed LAN IP in FTP tranfers in stead of Firewalls WAN-IP.
I'm having this problem. Remote site is connected to the internet in a fixet, multiple IP-adress MPLS setup. The LAN side is presently protected by a Zyxel Zywall, but for a variety of reasons I want to replace the Zyxel, and for that I chose a NETGEAR FVS318N. Manual: http://www.downloads.netgear.com/files/GDC/FVS318N/FVS318N_RM_26Apr2013.pdf From the LAN-side a device is transferring files to our FTP server, and this has been working as expected with the Zyxel firewall. The files for transfer are being renamed on the receiving FTP-server, after a succesful transmission. Now after the introduction af the FSV318 the rename operation is never completed, and the connection is timing out. I have configured the appropiate incoming firewall rules as well as the NAT translations between LAN- and WAN-IP adresses, and they have been tested to be correct. Routing mode on the NETGEAR FVS318N is set to NAT (p. 29 in the manual) 1. Select Network Configuration > WAN Settings, radio 'NAT' is selected. Neither VPN, Wireless or DHCP are active. Now I belive I have found what causes the error, by looking in the FTP-server's logfile: ----- start NETGEAR ----- Wed Sep 23 21:47:10 2015 300 111.111.111.101 77 /data/upload.file_1442964300.sea a _ i r olh ftp 0 * c Wed Sep 23 21:53:11 2015 301 111.111.111.101 41 /data/upload.file_1442964600.met a _ i r olh ftp 0 * c Wed Sep 23 21:59:12 2015 300 111.111.111.101 41 /data/upload.file_1442964900.met a _ i r olh ftp 0 * c Wed Sep 23 22:05:12 2015 301 111.111.111.101 77 /data/upload.file_1442964900.sea a _ i r olh ftp 0 * c ----- end NETGEAR –------ ----- start ZYXEL ------- Wed Sep 23 22:12:11 2015 1 111.111.111.102 41 /data/upload.file_1442965200.met a _ i r olh ftp 0 * c Wed Sep 23 22:12:18 2015 1 111.111.111.102 41 /data/upload.file_1442965500.met a _ i r olh ftp 0 * c Wed Sep 23 22:18:11 2015 1 111.111.111.102 77 /data/upload.file_1442965200.sea a _ i r olh ftp 0 * c Wed Sep 23 22:18:17 2015 1 111.111.111.102 41 /data/upload.file_1442965800.met a _ i r olh ftp 0 * c ----- end ZYXEL --------- NETGEAR-WAN-IP: 111.111.111.101 LAN-DEVICE-NAT-WAN-IP: 111.111.111.102 LAN-DEVICE-LAN-IP: 192.168.001.102 Incoming firewall rule is mapping 111.111.111.102 to 192.168.001.102, and is verified to work. In the FTP-server logfile it can be seen that when the NETGEAR is used, it (the NETGEAR) transmits its WAN-IP in stead of the NAT'ed WAN-IP of the transmitting LAN device. Since the FTP-client expects an answer to its own IP, it times out, because the response is sent to the WAN-IP of the NETGEAR. Both passive and active ftp has been tested, neither overcomes the problem. So the question is: How do is the NETGEAR FVS318N configured to transmit the NAT'ed WAN-IP of the transmitting LAN device in stead of the WAN-IP of the NETGEAR for FTP transfers?
