PIX 501 problem........ 1

[la6oca]

Hi folks. I just got a pix 501, 3 des - 10 user a few days ago. And i wonder what i am doing wrong.
With a basic setup, only alowing traffic out - it works great. But if i alow some traffic inside to port 21,23,25, 80 etc it is blocking everything. Olso the traffic out.
clear xlate does not help.

Its only 4 hosts on my home network, running adsl and pppoe

Any tips ??

HI.

Seems like the static commands are the problem:
static (inside,outside) 10.10.0.8 10.10.0.8 netmask 255.255.255.255 0 0
static (inside,outside) 10.10.0.36 10.10.0.36 netmask 255.255.255.255 0 0
static (inside,outside) 10.10.0.5 10.10.0.5 netmask 255.255.255.255 0 0

You should use in your case port forwarding instead, on the global ip of the interface.
Read here more about the "static" command:

http://www.cisco.com/univercd/cc/td/doc/product/iaabu/pix/pix_62/cmdref/qref.htm

and then please come back here with the corrected working configuration for other people to learn, or with further questions if it is still not working.

Thanks Yizhar, your tips did it.

I made that previour config via PDM 2.0 saw i thought it was correct. But i olso looked at those static lines in config you pointed out, and found them rare.
