DNS from ISP

Here's the deal:
 
 
        PC host------e0---R1---e1----------------> ISP's DHCP
Server-------DNS server's 4.4.4.4 4.4.4.5/16
 
 
 
interface Ethernet0
 ip address 139.2.25.3 255.255.255.0
 ip nat inside
 
interface Ethernet1
 ip address dhcp
 ip nat outside
 
 
ip nat inside source list 2 interface Ethernet1 overload
 
ip route 0.0.0.0 0.0.0.0 Ethernet1
 
access-list 2 permit 139.2.25.0 0.0.0.255
 
 
 
Problem:
 
On the PC host;
 
Static IP 139.2.25.254 /24
Default gateway - Ethernet 0's IP
Static DNS of ISP's DNS servers(2)
 
 
I debug ip nat translations detail:
 
05:53:38: NAT: i: udp (139.2.25.254, 5843) -> (4.4.4.4, 53) [56071]
05:53:38: NAT: s=139.2.25.254->4.46.28.254 , d=4.4.4.4 [56071]
 
No reply and no resolution.
 
Question:
 
Why doesn't the DNS make it back, and what's the solution?
 
I have other machines that are full DHCP clients, and that is how I
derived the DNS server addresses.
I can ping the ISP's df-gateway and DHCP server from PC host.
 
Thanks in advance!
