Need help with Packet Tracer

[Kaabi]

I'm in the CCNA program, and I'm using Packet Tracer for practice with designing networks. I'm good at making topologies, but when I run a simulation, the packets don't work when going to user devices, like computers, printers, or servers. However, it does work when going from a switch to a router or a switch to a switch. By work, I mean the packets (which are displayed as envelopes) arrive at the destination and a check mark flashes on them. When it doesn't work, Xes go through them. I have a large network where I haven't really tried to make it work, but I made a very small network with four hosts connected to a switch, and I added IP addresses and subnet masks to all the computers and it didn't work! I didn't modify the switch though, as I couldn't find any place on the switch to make modifications. So, what do I do?

Hard to say what is going wrong without seeing the exact topolgy and what you are trying to do. Such as, are there VLANs involved? Multiple switches? VTP? Trunks? Different IP subnets? etc. If you just take a switch out of the box and connect two PCs to it and assign appropriate IP addresses then they will be able to ping each other.

The fact that you didn't even check on the switch makes me feel that there must be something doing on there. Might be VLAN configurations you don't know about.

Also why are you doing network design for CCNA? That isn't really covered so much, more basics of networking and router/switch configuration.

It's just an assignment, I have to. There is no VLAN involved, I just took one switch, hooked four computers to it, and gave the four computers xxx.xxx.xxx.1 to xxx.xxx.xxx.4, where xxx.xxx.xxx were all the same. Also, the subnet mask was 255.255.255.224 for all of them, so I don't know what's wrong.

What about default gateway for the computers? Shouldn't be needed as they are all in the same subnet.

Are you able to connect to the switch and check the config?

Other than that I can't really say much else. Looks like everything else should be fine. What are the exact IPs you are using?

I wonder if someone can help me also. I'm using packet tracer 4 and have just started working through the CCNA 3 excercise called "handsonfinal" i think its called.

Well, i'm a little stuck. I'm trying to configure a static route, but the router isn't likeing the commands. Can someone tell me how I can create a static route, based on the screenshot below?

cheers

Basically you setup static routes as follows:

Router(config)#ip route 192.168.1.1 255.255.255.0 10.10.10.10

Which would tell the router that 192.168.1.1 is reached via 10.10.10.10. You can also use an interface.
