Issue

Servers are trying to access 2 DNS servers via the inside interface.

There is no outside interface, default route is via inside interface.

I thought it needed a nat (c_dmz) command but I got the following error message

PIX(config)# nat (c_dmz) 0 0.0.0.0 0.0.0.0 0 0

nat 0 0.0.0.0 will be identity translated for outbound

WARNING: Binding inside nat statement to outermost interface.

WARNING: Keyword "outside" is probably missing.

Any idea where I am going wrong?

"nat (c_dmz) 0 0.0.0.0 0.0.0.0 0 0" command only works for outbound connection, ie: from high to low security level.

Since you would like to pass traffic from c_dmz (security level 0) to inside (security level 100), ie: from low to high security level, then you would need the following command:

static (inside,c_dmz) 195.244.192.166 195.244.192.166 netmask 255.255.255.255

static (inside,c_dmz) 195.244.192.16 195.244.192.16 netmask 255.255.255.255

Hope that helps.
