Hi,

I've just received a CISCO PIX 506E Firewall and I wanted to add it into my existing home network.

Here is my current setup:

1) DSL Modem (WAN Port) to PIX (Ethernet0 Port)
2) PIX (Ethernet1 Port) to Linksys Switch (Port 1)
3) Linksys Switch (Port 2) to PC

This setup is currently working and I can get an internet connection on my PC but my first problem is that if I try to ping for example I get a request timed out on my PC although I can actually see the google page in a browser.

My second problem is that I'm trying to incorporate a Linksys Wireless-N Broadband Router in this setup.
I've tried many wiring combinations and nothing seems to work. How should I be connecting it to my existing setup and is there something I need to setup on the PIX?

Would appreciate someone's help over this.
 
You need to allow Icmp back into the firewall

access-list outside-in permit icmp any any echo
access-list outside-in permit icmp any any echo reply

access-list outside-in in interface outside


You dont need a wireless router in that setup, you need a wireless access point.
 
Unfortunately, it didn't work and I think there are some errors in your syntax. Here is my config:

There's absolutely no other way I can incorporate a router in my configuration? What if I remove my switch from it?
 
Sorry

access-list outside-in in interface outside


Should have been


access-group outside-in in interface outside
 
How are you trying to connecte the new router?
Do you have a topology?
 
I have a PIX as my edge device and still have a linksys and a netgear wireless router in place to handle the wireless. All i did was not use the wan ports on them and turn DHCP off. Now they are just like access points.
