Having problems -- I just want to open PIX to all traffic

I am having problems configuring my PIX 515/E.
Requirements:
-allow inside computers to map/view server shares on outside of pix
-allow tcp traffic on port 5450 for PI software (osisoft)

If there are suggestions for this I would appreciate any tips. Otherwise, I think I want to open all traffic and then start to limit as I understand more.

This pix is to segment controls computers on part of our network.

Thanks for any help
Andy
 
The PC's on the inside segment should be able to access any device on the outside segment without applying ACL's on the PIX.

Can the PC's access anything on the Internet (if you have Internet connectivity)?

Can the PIX ping the outside servers?

Could you post your config?
 
I am not doing nat, so on the computers behind the pix (x.x.24.0) should the gateway be the pix or the router (x.x.12.0) on the outside of the pix?

Thanks,
Andy

ok - scratch that previous post. I could not find a way to edit it. Wrong config.

Yes - I can ping servers outside the pix.
No - I cannot reach internet sites.
No - I cannot map / view server shares outside of pix

add the following statement:

global (outside) 1 interface


Remove the following statements:

no nat (inside) 0 access-list 103
no nat (inside) 0 x.x.24.0 255.255.255.0 0 0
 
inside is public. No nat or pat.

global (outside) 1 interface -- This broke ping to outside servers.

Yes. I understand now. In my haste I didn't initially ask you whether the inside IP's were private or public. I assumed private.

By, adding the global(outside) command you essential started to PAT your addresses.

Ok. Remove the global(outside). This'll fix it.

Now, you verified that you can ping the outside servers. But not the internet. Do you own the IP address space or is it part of you ISP's address space that they provided to you?

Since you can ping the servers, have you tried to map a drive?
 
Bell1996 thanks for your help.
The last piece to the puzzle was incorrect wins server info on the computer behind the pix. Once this was corrected, outgoing traffic works fine.

Thanks again,
Andy
