network3a: 1 Internet Connection

Question:

II have a problem reaching Catalyst Switches the internet from my second cascaded network 10.1.1.0 on Cisco 3550.

I can reach the internet while I'm using the network 192.168.1.0, but when ever I try from 10.1.1.0 I always get request timed out.

Here is the configuration:

Linksys X300:

Not much on it 2 static routes.

ip route 10.1.1.0 255.255.255.0 192.168.1.3

ip route 41.68.42.89(public) 255.255.255.255 172.31.1.122(first hop)

Linksys E900: >> IP address only

Cisco 3550:

Enabled ip routing

default route >> ip route 0.0.0.0 0.0.0.0 192.168.1.1

Ip default-gateway 192.168.1.1

ip name-server 192.168.1.1

SVI interface vlan 10

ip add 10.1.1.3 255.255.255.0

int fa 0/24

no switchport

ip add 192.168.1.3 255.255.255.0

Tests

I can ping from 10.1.1.0 to 192.168.1.0 and vise versa

I can reach the internet from 192.168.1.0

When I ping yahoo.com from 10.1.1.0 (computer) the dns work!! I mean it translates yahoo.com to 206.190.36.45 but it gives me request timed out.

Lastly I tried to ping from the cisco 3550 to 172.31.1.122 with source ip 10.1.1.3 and it also gave me the same request timed out.

Can you please help me guys I know I'm missing something and I dont know it and it is driving me nuts.

Answer:

Are you NATing the affected subnet?
