Cisco 501 Pix

Subject: Cisco 501 Pix
Date: 10 Jun 2007 18:26:28 -0000
Trying to setup a Cicso 501 Pix at home with a RoadRunner cablemodem 
connection.  I have a linksys wireless 2.4ghz gateway between the Pix and the 
cablemodem.  All connections through the linksys (pcs) work fine connecting to 
the internet.  The pix gets an ip address from the linksys fine, but it does 
not go out to the internet.  The ip addresses and domain name on the file below 
are not the actual ones, but the ones in the actual pix are valid from the 
network I need to connect to.  The linksys assigns an ip address of 
192.168.1.101 to the pix.  A pc connected to the pix will get an appropriate ip 
address from it e.g. 10.248.133.10.  Any idea why it does not go out to the 
internet?  I cannot ping the dhcp server (from the 2nd line here):

dhcpd address 10.248.133.10-10.248.133.19 inside
dhcpd dns 142.112.102.142 10.248.33.5


Pix configuration:
