Thanks, looks like I do need to setup a DNS server on the XP box. Any suggestions on a basic DNS server?

I have never set up a DNS server on an XP box, but Google seems to show a number of choices.<br />

If you can get a DNS translating firewall, that would be an easier choice. &nbsp;I think you can even do that with DD-WRT on a number of home router platforms like the Linksys WRT54G.

I have recently setup an inhouse e-mail server (Kerio) on XP Pro SP3. Network is a P2P with a Watchguard Firebox SOHO6 and Qwest DSL M1000 in bridged mode with static IP. Mx is configured correctly and appears to working fine. DNS addresses are Qwest ISP for primary and secondary.<br />
<br />
Prolem is that I can access network from outside using FQDN and IP but not from inside.<br />
<br />
However I can't connect using public IP with ping, tracert, HTTP or IMAP on the inside.<br />
Can connect using internal private IP.<br />
Have disabled firewalls and used host file to no effect.<br />
<br />
This is necessary inorder to allow laptop to connect to the e-mail server while off the internal network with changing host files or Ip settings.<br />
<br />
I'd prefer to not setup an internal DNS server (BIND, etc.), thoughts?

Unable to connect to hosted FQDN with public IP from LAN

Software firewalls, also known as host-based firewalls, provide a layer of software on one host that controls network traffic in and out of that single machine. Most operating systems now include firewall software, but many available software firewalls include central distribution, antivirus systems and disaster recovery.

Software Firewalls

Transmission Control Protocol/Internet Protocol (TCP/IP) is the set of networking protocols that define end-to-end connectivity specifying how data should be packeted, addressed, transmitted, routed and received at the destination. This functionality is organized into four abstraction layers which are used to sort all related protocols according to the scope of networking involved.

TCP/IP

The Domain Name System (DNS) is a hierarchical, globally distributed system responsible for associating the name of a computer, service or other resource into an IP address for connecting to the Internet or a private network. Most prominently, it translates domain names to the numerical IP addresses needed for the purpose of computer services and devices worldwide.
