Add a default route...

route outside 0.0.0.0 0.0.0.0

Hi Acomiskey,

Hope fine.

I am having a problem in my Pix FW to block a particular network to go to the internet. Here is the scenerio.

My FW has 3 interfaces: Outside(Sce 0), Inside (Sec100) and DMZ(Sce50). Whole inside block (let say 10.x.x.x) is being NATed (Here using DynamicNAT/PAT) to the Outside Interface while going towards Internet. NAT 0 is using between Inside and DMZ Servers to communicate. Here is the configuration.

nat-control

global (Outside) 1 interface

nat (Inside) 1 access-list nat

access-list Nat_ACL extended permit ip 10.0.0.0 255.0.0.0 any log

Now what the problem is - I want to block a specific network 10.10.10.0/24 to go to the the Internet. I tried to change the Nat_ACL ACL here by denying the 10.10.10.0/24 to any and then allow/permit 10.x.x.x to any. But it didn't work.

Any suggestion or ideas or any other way how can I block this 10.10.10.0/24 to go to the Internet. Ur help would be highly appreciable.

Hi,

I don't see any nat & acces list for DMZ traffic, also again check your static command.

Hi Adnan,

All you have to do is assigning an ACL (Not NAT Acl) to inside interface as following

access-list inside_access_in deny tcp 10.10.10.0 255.255.255.0 0.0.0.0 0.0.0.0 eq www

access-list inside_access_in permit ip any any

access-group inside_access_in in interface inside

Regards
