PIX DMZ Server cannot access the Internet

[jeffmck]

We have a PIX version 6.1 firewall through which our inside network can access the outside perfectly. The DMZ server however cannot. The only reason for having it access the outside or Internet is for upgrades and simple browsing (although this can be accomplished through terminal services). The internal nets are 10.1.1.0 and 10.2.1.0 and the DMZ server is on 10.3.1.0. Everything else but its outside access is working fine. Any ideas?

Are you using websense?

 

[ianbla]

have you an access-list allowing 80/443 traffic into the DMZ interface

This is what I have

access-list 121 permit tcp host 10.3.1.5 any eq www
access-list 121 permit tcp host 10.3.1.5 any eq 443
.....
.....
.....
.....
.....

access-group 121 in interface dmz

 

[jeffmck]

I am including a current copy of the PIX configuration - I tried using your sugestions but perhaps I applied them improperly. Where would I include the access list statements to allow the dmz server Internet access in our situation?

Result of PIX command: "show config"

It looks like your running websense or similar, but you didn't specify the filter commands

url-server (inside) host 10.1.1.17 timeout 5 protocol TCP version 1
url-cache dst 128KB

Are you running any web filtering software? If not, then remove the url-server and url-cache lines.

Also, I noticed that your access-list "dmz1_inside" isn't doing anything. I would recommend removing it, since it's just taking up cpu and you aren't filtering anything with it.
