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 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

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.

Hi,
can you put an IP address on interface 0/1?
interface FastEthernet0/1
ip address 192.168.1.1 255.255.255.0
duplex auto
speed auto
And see if you can ping it from the wireless laptop.

Thanks for the quick reply Reza! If I do that will it also conflict with the 192.168.1.1 address from the first linksys wireless router? I will do that but I feel as if it might be a conflict. Thanks again Reza!
04-17-2013 12:05 PM
Larry,
My apologies. I did not see that 1.1 was assigned to linksys. Make the 1841 interface 1.100 please.
04-17-2013 12:10 PM
Reza,
It has been set to manual 1.100. Lost my internet connection due to conflict with 1.1
04-17-2013 12:14 PM
Ok, so what was the IP address when you used DHCP? I thought, your diagram shows it is 1.100
If you change it back to DHCP, can you do sh ip arp and see what IP the DHCP assigned to 0/1?
04-17-2013 12:28 PM
When I used dhcp it also assigned .100

Ok, when you are logged in to the 1841, can you ping the linksys (1.1) or 101 or any of the servers in this subnet?
04-17-2013 12:35 PM
yes I can. I think it could be an ip route issue.
04-17-2013 12:39 PM
1841 is a router and by default IP routing is enable, but to be sure can you try enabling it one more time?
04-17-2013 12:43 PM
It has been enabled.
Parasite#sho ip route
Codes: C - connected, S - static, R - RIP, M - mobile, B - BGP

Gateway of last resort is not set

Here are the tests from pinging from the source of 0/0
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)
Parasite#ping 192.168.1.1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.1.1, timeout is 2 seconds:

Success rate is 100 percent (5/5), round-trip min/avg/max = 1/1/4 ms
Thanks Reza.

Larry,
Configuration register is 0x2142 (will be 0x2102 at next reload)
The config register needs to be 0x2102
Can you reboot and test again?
