Hi Pete, Thanks we are making head way. Here are the results. I even was able to give my test pc a 103 ip with the gw as 192.168.10.3 and I'm able to ping 104.1 and 104.2. Okay now that we have that work I now have a 192.168.148.0 and a 192.168.192.0 network that I need to be able to ping the 104 network. Can you please help me with that.

Mark,

Finally having some success, isn't it? :)

Regarding the 192.168.192.0/24 network, there are some discrepances. It is directly connected on your 3800 router. However, the static routing entry on your 2800 router for this network points towards a completely incorrect next-hop IP address. Therefore, enter these two commands on your 2800 router in the global configuration mode:

no ip route 192.168.192.0 255.255.255.0 192.168.103.10

ip route 192.168.192.0 255.255.255.0 192.168.104.1

I assume that the PCs in the network 192.168.192.0/24 can ping the 192.168.104.1 but can't ping the 192.168.104.2. This problem should be corrected by the two commands shown above.

Regarding the network 192.168.148.0/24, I do not know where it is connected. You have a static routing entry on the 2800 router for this network but I can not confirm if it is correct or not. The 3800 router does not have any information about that network. Without further info, I am not able to guide you further.

Best regards,

Peter

Hi Peter, I have confirmed I have set my test pc up using a 192.168.192.84 and a gw of 192.168.192.57 and yes I can ping the 104.1 but not the 104.2. I will make the ip route change on R2 na d lookm into the 148 network and let you know. Thanks so much for helpping me and sticking with me on this.

markwieseler · ‎08-05-2009

Hi pete, I have made the route change and now I can ping 104.2. Thanks

markwieseler · ‎08-05-2009

Sorry I meant to say Peter. Thanks

markwieseler · ‎08-05-2009

Hi Peter, I have been looking for the 192.168.148.0 network. I see its coming from our SonicWall with a ip of 192.168.148.1 and then going into a switch. Please correct me if I'm wrong but I thing what I need to do is take a network cable and go from the switch to fe1/1 on R1 na then change the route on R2. Thanks

Hello Mark,

I am not completely sure if you are suggesting a topology change - making changes in your network physical cabling. That's not our task here. Right now, we should try to make the network run as is.

I am missing the topology of your network. I have been able to guess some part of it by looking at the configurations of your two routers but for the remaining part, I have too little information. That SonicWall is a completely new information to me and even if I know that it exists, again I do not know where it is located, whether it works as a bridging or routing firewall, where exactly it is connected and so on. Is it perhaps possible to make a detailed graphical depiction of your existing network topology, say, in Visio or XFig/Dia? That would help me further.

Mark, allow me a personal question - how long are you with IP networks and how do you personally assess your skills in IP networking? This will help me understand your situation better.

Best regards,

Peter

"ip route 192.168.104.0 255.255.255.0 192.168.104.1"

You should try to put your next hop and not your local interface IP address.

markwieseler · ‎08-03-2009

Are you talking about the router that has a ip of 192.168.104.1 or the router that has the ip of 192.168.104.2
