Help configuring IP routing Cisco 1720

We have a 1720 with serial port and one ethernet card. Used to provide frame relay internet access to internal networks. I Would like to provide routing to additional subnets ie Can anyone help with configuring a 1720 router to provide addtional ip address ranges to the existing range for the serial port eg existing address to 155 ( range - 143 . I Would like to use the additional IP addresses to connect Qty 2 PIX501 firewall routers to connect the new subnets and provide individual and seperate internal networks

eg 192.168.(0 - 2) .0.

Re: Help configuring IP routing Cisco 1720

so, you still have 1 router with 1 serial and 1 ethernet.

You're going to attach 2 firewall to the ethernet LAN and have different internal address behing the firewall. Is it correct ?

If so, you can just use static routes.

On the router enter the following commands :

ip route pix-1-ip-address

ip route pix-2-ip-address
