Ping troubles

andymoore88

Okay, I'm a bit of a lurker here, loads of info and you folks have helped me in the past, whether you knew it or not
I've finally gotten around to officially getting my Home lab up and running, I finally feel like I've learned enough to make use of it.

I've got three routers hooked up at the moment, R1 = 2620XM, R2 = 2611, and R3 is a 2620. I have switches that will be incorportated later.

For now, I run a cable modem to a wireless lynksis E1000. From there I run to my home network seperately from my Home Lab, I can't accidentally take down my Wife's internet connection, now can I? lol

Currently my issue is that I can ping google.com from R1, but I can't do that from R3 or R2. I have scoured these routers, but I am failing to see what the issue is.

I can ping the connecting interface between routers and the outbound interface on R1, but it stops there.

I can't get past address translation when traceroute from R3. Use google's IP address and ping fails, traceroute makes it to the inbetween interface, but stops there.

Anyone have a few moments to spare for this? I know it will be something blatantly simple and I'm fully prepared to feel emabarassed, lol.

Thanks in advance,
Andy

Have you got static / default routes set up both ways on the connecting routers?

andymoore88

I believe the routing tables are complete, yes sir.

AndyR3#sho ip ro
Codes: C - connected, S - static, I - IGRP, 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, E - EGP
i - IS-IS, 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 0.0.0.0 to network 0.0.0.0

R 192.168.1.0/24 [120/1] via 192.168.3.1, 00:00:19, Serial0/0
R 192.168.2.0/24 [120/1] via 192.168.3.1, 00:00:19, Serial0/0
C 192.168.3.0/24 is directly connected, Serial0/0
S* 0.0.0.0/0 is directly connected, Serial0/0

AndyR1#show ip ro
Codes: C - connected, S - static, R - RIP, M - mobile, B - BGP

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

C 192.168.1.0/24 is directly co92.168.2.0/24 is directly connected, Serial0/0
C 192.168.3.0/24 is directly connected, Serial0/1
S* 0.0.0.0/0 [1/0] via 192.168.1.1


192.168.1.1 is the wireless Lynksis E1000

Does your wireless router have routes to reach the 192.168.2.0/24 and 192.168.3.0/24?

If you ping from R1 sourcing from S0/1, does that work?

andymoore88

I will see if I can add static routes for the .2 and .3 networks. I bet that is the problem. I'll update soon as I can.


No, I cannot ping google.com from R1, sourcing from s0/1.

andymoore88

Well! There ya go folks, my wireless linksys had never heard of my subnets, and that was the problem. Thank you Eten! And everyone else!!!

I love this site!

Hi.. the problem is exactly what u said about your linksys router not knowing the routes to your subnet. all u need to do is to configure NAT on the router that connect your subnetworks to your home network.

JeanM

Yep, always think that routing goes both ways
