<\/strong><\/p>\r\n

Connect to the Windows 2003 Server with Remote Desktop Login to the Server.
Go to Start -> Control Panel -> Network Connections -> Local Area Connection

Click on “Properties,” then navigate to “Internet Protocol (TCP\/IP)” and click on “Properties.” From there, access the “Advanced” settings and click on the “Options” tab.

Highlight TCP\/IP filtering and then click properties
Check the box labeled \u201cEnable TCP\/IP Filtering (All adapters)\u201d At this point, you should select the TCP\/UDP\/IP Ports and Protocols necessary to operate the server. You will select \u201cPermit Only\u201d and list the ports or protocols you will permit to pass through the filter.<\/p>\r\n\r\n\r\n\r\n

For example:<\/strong><\/p>\r\n\r\n\r\n\r\n

TCP Ports
20 – FTP
21 – FTP
25 – SMTP
53 – DNS
80 – HTTP
110 – POP3
443 – HTTPS
3389 – RDP – Remote Desktop Connection
!!!!IF YOU DON\u2019T DO THIS, YOU WILL NOT BE ABLE TO GET BACK INTO THE SERVER!!!!
8080 – Urchin Webserver
19638 – Ensim
8098 – TCP port for default-installed Web management<\/p>\r\n\r\n\r\n\r\n

UDP Ports
53 – DNS<\/p>\r\n\r\n\r\n\r\n

IP Protocols
1 – ICMP (Optional – Used for ping and other administrative packets)
6 – TCP
17 – UDP<\/p>\r\n\r\n\r\n\r\n

Select OK, OK, OK, OK, then Yes to REBOOT<\/p>\r\n\r\n\r\n\r\n

CAUTION
Failure to follow this correctly could require manual intervention to enable you to reconnect to the system.<\/p>\r\n\r\n\r\n\r\n

NOTE<\/p>\r\n\r\n\r\n\r\n

Ensim creates anonymous ftp connections for each domain and uses a nonstandard port number for each site starting at around 10003. If you will be supporting anonymous ftp on name-based sites with these numbers, you will need to enable the TCP ports used by each site that will use anonymous ftp on name-based sites.<\/p>\r\n\r\n\r\n\r\n

Advice to people that have enabled the Embedded 2k3 STD Firewall is to take it down if they want to add additional IPs to their boxes as the TCP-IP config does not behave correctly. After you close it, add the 2 extra ips, restart and enable the firewall again<\/p>\r\n\r\n\r\n\r\n

Get the adapter\/computer to recognize the extra IP<\/p>\r\n\r\n\r\n\r\n

Login to remote desktop<\/p>\r\n\r\n\r\n\r\n

    \r\n
  1. Start – Settings – Control Panel – double click on Network Connections<\/li>\r\n
  2. Right click on Local Area Connection and choose Properties<\/li>\r\n
  3. Scroll down to Internet Protocol (TCP\/IP) select it, and click Properties<\/li>\r\n
  4. Click the Advanced tab at the bottom right<\/li>\r\n
  5. You will see your current IP address. Click ADD and add the two IP addresses with the correct Subnet Mask provided to them by RS.<\/li>\r\n
  6. Click OK on all windows, and the network service should restart. If not, reboot. They should be assigned after that.<\/li>\r\n<\/ol>\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n
