Hi Lonnie OK, so that's not the explanation of why my RDP session would not connect. Basic networking question follows:
This Astlinux box is not the gateway for our Windows boxes. Does this mean that, even if I set a port-forward up right on the Astlinux box (which I think I did), there is no way to get the Windows box to send it's reply via the Astlinux box, rather than via the normal gateway (which in this instance was down, which is the problem I am trying to solve)? Thanks for all the help Tom -----Original Message----- From: Lonnie Abelbeck [mailto:[email protected]] Sent: 10 December 2012 15:47 To: AstLinux Users Mailing List Cc: Tom Chadwin Subject: Re: [Astlinux-users] NAT rule Hi Tom, The Firewall tab's "NAT EXT:" entry specifies which external IP the rule applies to, by default it is 0/0 which is any external IP. You probably only have one external IP address. So, something like this would work for RDP -- NAT EXT-LAN Protocol: TCP Src: 0/0 Port: 3389 Dst: 192.168.100.10 Port: 3389 NAT EXT: 0/0 { Restart Firewall } - _x_ Confirm -- For the advanced, special case where your external interface has more than one static IP address defined via the Advanced variable EXTIP_ALIAS (user.conf): EXTIP_ALIAS="1.2.3.11" In this case, in addition to the static external IP address defined in the Network tab (assume 1.2.3.10), the 1.2.3.11 address will also be 'aliased' to the same external interface. For this case when NAT'ing, you can use: -- NAT EXT: 1.2.3.10 -- or -- NAT EXT: 1.2.3.11 -- or -- NAT EXT: 0/0 -- to specify if the NAT rule should apply to only 1.2.3.10, or only 1.2.3.11 or both 0/0.
