Join 2 Networks

Howdy, I have a cisco 1720 router, windows 2003 PDC, 2 2950 cisco switches 1 cisco PIX.

Network1. The PDC acts as DHCP and has to authenticate all users and gives ip 192.168.0.x.

Network2. Has PIX 192.168.10.x with applications behind it.

I would like to join the 2 networks all clients on network 1 to communicate with network 2 without changing the current topology. I have tried vlans with no success. Please assist

Since the PIX is the default gateway for network 2, I guess you would need an extra interface on the PIX to connect to the 1720.

I do not believe the PIX will send packets packet backout the same interface they arrived on.

Set up routing on the PIX and the 1720 accordingly.

For network 2, what is the model of the PIX and what software version is it running.

IFor network 2 , is there a layer 2 switch connected to the PIX ?

If not then what do the devices having IP address 192.168.10.x connect to ?

Are both network 1 and 2 in the same location ?

For network 1, are both 2950's interconnected , then one of them connected to 1720 ?

Post output of show version for the 1720

Yes, give us your topology configuration w/ip addresses so we can get a better idea of how your network is currently set up.

The current topology is Network 1 I have 60 machines they get get IPs from a DHCP 192.168.0.x they all connect to 2 48 port cisco switch 2950XL and 1 1720 cisco router has two interfaces 1 to the internet the other to local LAN Network 2 has 4 servers with IPs 10.0.0.x a switch and cisco PIX firewall, the pix has 2 network interfaces 1 is GW for the servers and

192.168.10.x for the external network. Incase i want to access servers on network 2 I have to change the ips 192.168.0.x to 192.168.10.x with a GW of PIX outside interface. I want to join both networks. I do not want to keep on changing the addresses. As requested below is a show ver for 1720
