Setting up a learning lab with errors

Hi all,

Hope everyone is doing well. I am currently setting up a home lab environment and have run into a bit of an issue and I am trying to wrap my head around it. Basically the setup is NetworkPlaying.png and I can ping from the wireless laptop to the interface 0/1 on the 1841 but not to 192.168.1.1 or any of the servers on the 192.168.1.0/24 subnet. I am also trying to pass internet traffic to this subnet with no success. So I have beat my head against the wall and that didn't help(just left a nasty oil spot on the wall....) Here is the config for the 1841:

version 12.3

service timestamps debug datetime msec

service timestamps log datetime msec

no service password-encryption

!

hostname Parasite

!

boot-start-marker

boot-end-marker

!

!

no aaa new-model

!

resource policy

!

memory-size iomem 15

mmi polling-interval 60

no mmi auto-configure

no mmi pvc

mmi snmp-timeout 180

ip subnet-zero

ip cef

!

!

no ip dhcp use vrf connected

ip dhcp excluded-address 10.1.10.1 10.1.10.99

!

ip dhcp pool WireLessPool

   network 10.1.10.0 255.255.255.0

   default-router 10.1.10.1 255.255.255.0

   domain-name LarrysLab.local

control-plane

!

alias exec s show ip int br

alias exec sr show run

!

line con 0

logging synchronous

line aux 0

line vty 0 4

end

I am probably screwing this all up, but it's a learning day and I will destroy this many times before the day is out. Thanks for your help.

Reza,

I have changed the register and rebooted, now I cannot ping 4.2.2.2?

-Larry

ok how about this test again

Parasite#ping 192.168.1.1 source 10.1.10.1

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 192.168.1.1, timeout is 2 seconds:

Packet sent with a source address of 10.1.10.1

.....

Success rate is 0 percent (0/5)

If good, how about pinging a server from the wireless laptop?

Reza,

ok, I changed the interface 0/1 to dhcp and now I can ping 4.2.2.2 but still cannot ping 192.168.1.1 source 10.1.10.1

-Larry

Larry,

how about from the laptop?

Can the servers ping 192.168.1.1?

Do the servers have default gateway?

Hey Reza,

The servers have a default gateway of 192.168.1.1 and they can ping it and communicate with the internet just fine, the laptop(10.1.10.101/24) cannot ping 192.168.1.1/24 or communicate with the internet.

Thanks Reza.

-Larry

Can you add a default route to the router

ip route 0.0.0.0 0.0.0.0 192.168.1.1 (linksys)

can the servers also ping 192.168.1.100 (1841 interface)?

Route added

The servers can ping the interface 192.168.1.100.

Here are a few test after adding the requested route.

Parasite#ping 4.2.2.2

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 4.2.2.2, timeout is 2 seconds:

!!!!!

Success rate is 100 percent (5/5), round-trip min/avg/max = 8/11/16 ms

Parasite#ping 4.2.2.2 source 10.1.10.1

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 4.2.2.2, timeout is 2 seconds:

Packet sent with a source address of 10.1.10.1

.....

Success rate is 0 percent (0/5)

Parasite#sh ip route

Codes: C - connected, S - static, R - RIP, M - mobile, B - BGP

       D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area

       N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2

       E1 - OSPF external type 1, E2 - OSPF external type 2

       i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2

       ia - IS-IS inter area, * - candidate default, U - per-user static route

       o - ODR, P - periodic downloaded static route

Gateway of last resort is 192.168.1.1 to network 0.0.0.0

     10.0.0.0/24 is subnetted, 1 subnets

C       10.1.10.0 is directly connected, FastEthernet0/0

C    192.168.1.0/24 is directly connected, FastEthernet0/1

S*   0.0.0.0/0 [1/0] via 192.168.1.1

Thanks,

Larry

Ok so...

Parasite#ping 4.2.2.2 source 10.1.10.1

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 4.2.2.2, timeout is 2 seconds:

Packet sent with a source address of 10.1.10.1

.!!!!

Success rate is 80 percent (4/5), round-trip min/avg/max = 8/10/12 ms

No I can ping from the subnet 192.168.1.0 to 10.1.10.0. THIS was due to a misconfiguration in the main router coming off of the internet and it not having the correct static routing setup. My mistake and sorry we wasted time troubleshooting the wrong device.

Now, if I could only get the internet working on the laptop(10.1.10.101)

Thanks for all your help and time so far with this Reza.
