I am having a problem with two of my Cisco 1600 routers. They are<br>

connected to each other via a private T1 connection and have the<br>

following configuration<br>

<br>

Router1:<br>

e0=192.168.1.1 mask 255.255.255.0<br>

s0=Admin. Down<br>

s1=CSU/DSU WIC 192.168.3.1 mask 255.255.255.0<br>

eigrp is enabled with networks:<br>

192.168.1.0<br>

192.168.2.0<br>

192.168.3.0<br>

<br>

Router2:<br>

e0=192.168.2.1 mask 255.255.255.0<br>

s0=Admin. Down<br>

s1=CSU/DSU WIC 192.168.3.2 mask 255.255.255.0<br>

eigrp is enabled with networks:<br>

192.168.1.0<br>

192.168.2.0<br>

192.168.3.0<br>

Default Gateway: 0.0.0.0 0.0.0.0 192.168.3.1<br>

<br>

<br>

This configuration has worked fine for connecting this remote office<br>

the the home office but now I am trying to connect this office to the<br>

internet and here is my problem. From a terminal screen in ROUTER1 I<br>

can ping 192.168.2.10 (server at the remote office) but I can not ping<br>

192.168.1.10 (Server at Home Office) from ROUTER2. What puzzles me is<br>

that I can ping 192.168.1.1 from ROUTER2. I can connect to ROUTER1<br>

and ping 192.168.1.10 so I know that it can see it but for some reason<br>

192.168.1.10 can not be reached from within ROUTER2. As for the<br>

network I can be at any workstation at the remote office and ping<br>

192.168.1.10 all day long but not from within the ROUTER2 itself. I<br>

believe that this is what is causing my internet connection problem.<br>

Any and all help would be GREATLY appreciated as I have been knocking<br>

myself out for over a week on this problem. I know it's probably<br>

something silly I'm doing.<br>

<br>

Steve,<br><br>&nbsp;&nbsp;&nbsp;&nbsp;Can you post your running config?&nbsp;&nbsp;Just curious about this problem.<br><br>Thanks<br><br>Jason
 
What does the routing table on the server 192.168.1.10 look like?&nbsp;&nbsp;Does it know how to get to the network 192.168.3.0/24?&nbsp;&nbsp;If I understand your description correctly, I'll bet it doesn't.&nbsp;&nbsp;I doubt this is your internet problem. <br><br>You don't give any indication as to where the Internet connection is located.&nbsp;&nbsp;Where is that connection?&nbsp;&nbsp;What do the routing tables on all three routers (the two in your previous post and the Internet router) look like?
 
The 2 other responses have valid questions too your application. A show of your running config would be needed for review . How are you trying to get the internet working ? Through a frame-relay to an ISP ! These questions would need to be answered for any help could be given .&nbsp;&nbsp;
 
Have you tried an extended ping ? Instead of a standard command line ping...ie<br>Router#ping<br>Protocol [ip]:<br>Target IP address: 1.1.1.1<br>Repeat count [5]:<br>Datagram size [100]:<br>Timeout in seconds [2]:<br>Extended commands [n]: y<br>Source address or interface: 2.1.1.1<br>Type of service [0]:<br>Set DF bit in IP header? [no]:<br>Validate reply data? [no]:<br>Data pattern [0xABCD]:<br>Loose, Strict, Record, Timestamp, Verbose[none]:<br>Sweep range of sizes [n]:<br>Type escape sequence to abort.<br>Sending 5, 100-byte ICMP Echos to 1.1.1.1, timeout is 2 seconds:<br><br>Also where have you got the network of 192.168.2.0 configured in EIGRP ? Not a diretly connected network ? I assume that 192.168.1.10 has route back to router2. What is probaly does not have is any knowledge of the interconnted network between the router1 and router2 ie 192.168.3.0 subnetwork. <br><br>When you ping from router2 to 192.168.1.10 you will use the source address of 192.168.3.2 instead of the LAN(ET0) Address.<br><br>Run an extended ping and input the source address of 192.168.2.1 and it will work or input a static route into 192.168.1.10 for network 192.168.3.0 via 192.168.1.1<br><br>That will sort ya<br><br>Regard<br><br><br>&nbsp;<br>
