I have an ADSL Alcatel Router 510i which is connected to the internet. Its working. When I insert the PIX520 in the middle, I cannot connect to the internet. My PIX configuration is simple. The Aclatel takes care of NAT.
here is my configuration:
access-list 100 permit icmp any any echo-reply
access-list 100 permit icmp any any time-exceeded
access-list 100 permit icmp any any unreachable
interface ethernet0 auto
interface ethernet1 auto
ip address outside x.x.x.1 255.255.255.0
ip address inside y.y.y.251 255.255.255.0
nat (inside) 1 y.y.y.0 255.0.0.0 0 0
access-group 100 in interface outside
route outside 0.0.0.0 0.0.0.0 x.x.x.2 1

Hola Fernando --
Try disabling NAT on you Alcatel Router and let the PIX handle NAT'ing for you and see what happens,
As a suggestion here are the six basic steps to get PIX up and running:
1 - nameif ethernet0 outside security0
nameif ethernet1 inside security100
2 - interface ethernet0 100full
interface ethernet1 100full
3 - ip address outside 192.168.1.2 255.255.255.0
ip address inside 10.0.1.1 255.255.255.0
4 - global (outside) 1 192.168.1.10 192.168.1.254 netmask 255.255.255.0
5 - nat (inside) 1 0.0.0.0 0.0.0.0 0 0
6 - route outside 0.0.0.0 0.0.0.0 192.168.1.1 1--->this is the metric for the next hop router
The IP addresses above are all for example only.
Hope this helps --

Hi,
First of all thank you. I tried exactl what you suggested (incl deisabling NAT on Alcatel) and still could not get it to work.
The only difference in my configuration was that I omitted the global outside command.
any other ideas?
thanks

Hi --
OK, that didn't help.. Mmm, Will it be possible for you to either pate your config of the Alcatel and also the config for the PIX. If you like you can e-mail it to me, that is if don't want to post it on this forum.
Please make sure that you exclude any 'real' IP addresses and passwords etc.
Thanks --
