Multiple public IP's on my connection RRS feed

  • Question

  • My firewall supports having multiple Public IP addresses.  I have the primary IP address set on the Firewall, and the default ports redirect to a web server.  I have my firewall to redirect the second public IP address to my WHS, which works just fine if I try to access my WHS by IP address.  When I try to use the DNS name I setup at homeserver.com the dns entry is always set to the public IP of the firewall, not the secondary public IP address.  I there a way to force the xxx.homeserver.com DNS entry to a specific IP address?

  • No, you can't force a particular IP address from your server. So, unless your router allows you to configure requests from a specific internal IP to go out on a specific external IP, probably the router will use your primary IP as the origination point for everything (including your server). You'll find information on that in your router's configuration documents, if it can be done at all.
    I'm not on the WHS team, I just post a lot. :)

  • I added an outbound rule for all ports.  for my private ip for my home server I now always use the second public IP.  That did the trick.  The key is using a decent firewall.  I purchased the netgear 338, and it allows multiple public IP addresses.  Thanks Ken.
