Help configure a 2620xm

[tony]

Hi I have a cisco 2620xm and have added a adsl-wic1 nw-2w and want to use it as a home modem router.

I have got as far as I have setup ATM0/0 and all is good as i can ping outside of my home network.

I have also setup dhcp and it works fine and i can ping inside the my network.

I cant get ATM0/0 and fa0/0 to talk through each other.

I am only new at this cisco ios gig so please be patiant with me.

Here is my running config if some can help me and see what i am missing..

Thanks Tony..

Hi,

Can you change this:

access-list 1 permit 0.0.0.253 255.255.255.0

to this:

access-list 1 permit 192.168.0.0 0.0.0.255

and test again?

Hi Reza

Thanks for the reply.

It got very late last night before i gave up.

i managed to change

dns-server  192.231.203.132 192.231.203.2 to dns-server 192.168.0.5 192.168.0.6  which is wrong and i dont know how to change it back.

I added the line you said and  I dont how to remove the org line.

here is my running config again and also the startup txt.

sorry mate Iam no cisco ccna, just a motor mechanic that plays with pcs and networks as a hobby.

Thanks Tony Donn.

Hello Tony,

If you want delete some command from cisco, you have to negate it with "no" keyword. As Reza said, you have to change ACL 1 and also you have mismatched gateway IP address in DHCP configuration with Fa0/0 IP address.

This config should do the trick for you, copy&paste it and check if everything is working.

enable

conf t

no access-list 1 permit 0.0.0.253 255.255.255.0

ip dhcp pool 192.168.0.0/24

no default-router 192.168.0.1

no dns-server 192.168.0.5 192.168.0.6

dns-server  192.231.203.132 192.231.203.2

default-router 192.168.0.253

Best Regards

Hi Reza and Blau..

I ended up write erase and started again with reza recommandation on that line and it works..

thanks heaps guys and here is my final config that works for me..

Now I have it working as a basic modem router.

I have a a h323 gatekeeper that has endpoints reg to it that can call each other no probs it also passes calls that have 11 digits and start with 61 to a gateway that isnt there yet so the call fails.

I want to use the 2620xm as a gateway for my gatekeeper to pass calls to the PSTN via SIP account, and i think i have my work cut out for me so any help would be great.

it has NW-2W and ATM-AIM Voice 30.

Thanks again guys and you have made me very happy i have been hacking at this for weeks, many late knights..

Tony Donn..

VPI/VCI: 8/34

ATM Class: UBR

Accept Frame Type: ALL
