I have a Cisco router with 2-ethernet ports and 1-serial port in use.
The serial port a frame relay to my ISP for my internet access.
The first ethernet port is configured with one of my public ip's going to a pix firewall.
I want to use the second ether port with a 10.x.x.x/24 subnet to just allow internet access. Basically this port will go to a dedicated switch running a dhcp wireless router, thus creating kind of a DMZ of sorts.
The ip route 0.0.0.0 0.0.0.0 x.x.x.x where x.x.x.x is the public IP to my ISP is in place.
The wireless and switch work, allowing me to ping the ethernet port, the ISP public ip on the serial port, and my public ip on my first ethernet port. However, I can not ping any public addresses, like google, yahoo, etc.
I thought that the ip route 0.0.0.0 0.0.0.0 x.x.x.x (where x.x.x.x is the public ip to my isp) basically routed all public traffic that hit the router out of that serial interface.
Am I correct?
Can someone let me know if this is possible?
The goal is to allow the 10.x.x.x/24 network off of the secondary ethernet port internet access. Thanks to anyone for any help or guidance.
