Join 2 Networks

Oct 12, 2007 5 Replies

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.

Both networks have a default network 10.1 and 0.1 can i use Vlans to join the 2 networks if so how.

Thank you

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
