As usual, I will like to seek your enlightenment on a question related to NAT.
192.168.4.4 = DiGi GPRS DNS1 server (Primary)
192.168.4.5 = DiGi GPRS DNS2 server (Secondary)
Now, we have the following so that external parties can initiate DNS queries to the above 2 GPRS DNS servers -->
static (gprs,outside) 18.104.22.168 192.168.4.4 netmask 255.255.255.255 0 0 (NAT for primary DNS server: DNS1)
static (gprs,outside) 22.214.171.124 192.168.4.5 netmask 255.255.255.255 0 0 (NAT for seconday DNS server: DNS2)
However, we had not defined any "NAT" command translation rules so that the 192.168.4.x hosts can start an outbound connection (ie DNS query) to the external parties. This is because, I thought that we need to use the "NAT" command so that, only then the internal 192.168.4.x hosts needs to be translated to global addresses (64.124.233.x) before they can initiate DNS query to the external party.
However, according to my observation, the current 192.168.4.x hosts can PING to the outside world, as the PING results to Aicent's DNS servers and other GPRS roaming partners's DNS servers are successful.
Why ? Is there something wrong with my understanding in using the "static" or "NAT" command ? Please help enlighten me on this. Thanks ! :-)
