      <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;Alias would help you here if your server was on a dmz. But since the server is also on the inside alias will not help you. I assume this is pix version 6? Version 7 would allow you to hairpin on the inside interface and use destination nat. Something like this...&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;static (inside,inside) 60.60.60.100 192.168.1.100 netmask 255.255.255.255&lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>
