Linux Internet NAT problems with Cisco

Hello all, I recently installed Mandrake 10.1 on my two systems at my house. Both have internal IP addresses and have static NAT translation from my cisco 1605-r. My systems have been having some strange problems, the BIND server both installed by rpm then by source, 9.x and 8.x cannot resolve outside of my local network even after putting listen requests on eth0 and eth0:1

Besides that, the one system is having problems with the apache webserver with resolving request it looks like.

This is what I have, pretty identical on both systems.

Cisco 1605-R entry:

ip nat inside source static 10.0.0.100 208.15.25.67
ip nat inside source static 10.0.0.109 208.15.25.109

Linux Interfaces:

eth0 Link encap:Ethernet HWaddr 00:03:47:C2:07:CB

Linux Routes:

Code:


Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
208.15.25.0     0.0.0.0         255.255.255.128 U     0      0        0 eth0
10.0.0.0        0.0.0.0         255.0.0.0       U     0      0        0 eth0
0.0.0.0         10.0.0.1        0.0.0.0         UG    0      0        0 eth0

any ideas?
