I am trying to configure a Cisco PIX 500 firewall to work on a LAN. I configured it the best way I could according to information I have found. I have 2 public IP addresses available which are xx.xx.xx.162 & xx.xx.xx.163 and I would like to use PAT since there is only 1 Public IP available.
xx.xx.xx.161 is the gateway and it is a DSL router with bulit in firewall...I disabled the firewall so that it will not interfere. My LAN is on a 192.168.0.0/24 network behind the PIX.
nameif ethernet0 outside security0
nameif ethernet1 inside security100
ip address outside xx.xx.xx.162 255.255.255.248
ip address inside 192.168.0.1 255.255.255.0
global (outside) 1 xx.xx.xx.163
nat (inside) 1 0.0.0.0 0.0.0.0 0 0
route outside 0.0.0.0 0.0.0.0 xx.xx.xx.161 1
I cannot understand as to why the LAN cannot access the internet. Is there something more I have to configure as far as the NAT/PAT goes? Access list perhaps? not sure. Thank you in advance.
