I am new to cisco and I just want my computer links to internet.

[852]

Dear All,

I have a cisco 2600 router and connect two subnet.

subnet A ------cisco -------subnet B -----to internet

that is, in IP:

10.106.174.x ---10.106.174.253---10.106.159.253---10.106.159.x ===> Internet

In subnet B I can go to internet with a gateway 10.106.159.254

How can I get subnet A also go to internet using the same internet access.

should I use route-map or should I add a access-list?

Thanks a lot !!

Im a little lost here, lets try this. for testing setup a static route on the cisco to point to the internet

ip route 0.0.0.0 0.0.0.0 10.106.159.254

is the internet connection on the router?
show a config minus your passwords.

Thanks Fisher,

Let me explain it more.

The cisco 2600 have two ethernet port with IP
10.106.159.253 and 10.106.174.253, it connect to two subnet, one is 10.106.159.x, another is 10.106.174.x

at one side (159 subnet) have a internet access. Now I just want the 174 sunbet also get thourgh the router and go to internet.

have a graph:

Internet
|
|
10.106.159.254
|
|
HUBS----10.106.159.x
|
|
cisco 2600 (as above two ethernet port)
|
|
HUBS ---- 10.106.174.x

Thanks a lot

ok, have you tried to setup a gateway of last resort
default-gateway Jeter@LasVegas.com

are you running Dynamic Routing Protocol or just static routes? If you are running Dynamic you need to include the network number in your protocol.
Example
Router rip
network 172.16.0.0
and any other network that is not in this range.
if you are running static route you need to add a static route to your router.

Good luck

Thanks, but I am very very new to this. In the router I see the following, can anyone explain it to me:
I am using cisco 2600, I don't know I have rip or dynamic route protocol or not, I just first came to here on cisco.
Even I don't know how to add a static route on the cisco. Please help me.

Hello jeter,

Can you tell me what is the following meaning? It was set by pervious one, I don't know what he do,

access-list 101 permit tcp 10.106.159.0 0.0.0.255 10.106.174.0 0.0.0.255 gt 1023 established
access-list 101 permit udp host 10.106.159.1 eq netbios-dgm 10.106.174.0 0.0.0.255 eq netbios-dgm
access-list 101 permit tcp host 10.106.159.1 gt 1023 10.106.174.0 0.0.0.255 eq 139
access-list 101 permit icmp 10.106.159.0 0.0.0.255 10.106.174.0 0.0.0.255 echo-reply
access-list 101 deny ip any any log
no cdp run

Beside, I will try your suggestion. Thanks a lot.

access-list 101 permit tcp 10.106.159.0 0.0.0.255 10.106.174.0 0.0.0.255 gt 1023 established

this means the network of 10.106.159.x and 10.106.174.x will connect via a greater then port 1023 and use established TCP session

access-list 101 permit udp host 10.106.159.1 eq netbios-dgm 10.106.174.0 0.0.0.255 eq netbios-dgm

this is allowing netbios datagrams from 10.106.159.1 to anyone on network 10.106.174.x

access-list 101 permit tcp host 10.106.159.1 gt 1023 10.106.174.0 0.0.0.255 eq 139

Again.. allows the host 10.106.159.1 use a port greater then 1023 to connecto any host 10.106.174.x using port equal to 139 ; this is pretty unique entry

access-list 101 permit icmp 10.106.159.0 0.0.0.255 10.106.174.0 0.0.0.255 echo-reply

This allows any host on the 10.106.159.x to ping any host on 10.106.174.x network

access-list 101 deny ip any any log

This entry is not really needed but they are trying to log exceptions to the list.
