Cisco 837 ADSL router configuration help needed!!

azzaams

Hello guys;

I have a cisco 837 router trying to get it configured to work with my dsl provider. It connects and getting dsl sync I am having routing problem or firewall problem traffic is not getting routed. If any one can provide some basic config that will work , I greatly appreciate it. Here is the scenario;

inside network : 10.1.4.0
Router address : 10.1.4.1

Static ip (ISP eg) 205.50.50.40
Gateway : 205.50.50.10
dns 1 : 205.50.40.10
dns 2 : 205.50.30.10

vpi/vci : 0/35

www port forwarding to : 10.1.4.4

1. I have tried with some sample config found on the net. It connects to isp, I can see the incoming traffic is getting denied by one of the acl rule (in the hyperterminal)

2. When I try to test the connection in SDM it fails at 'checking exiting interface' when sdm trying to ping the dsn server it fails there saying problem with exiting interface ?


I can play around with firewall and acl rules once it is working. So I need some sample config or advice.

Thanks in Advance

From the router can you ping the outside world? You should be able to telnet/ssh into your router and then issue a ping command from the router.

- I tried pinging through the hyperterminal and it does not ping
- I tried pinging through SDM it does not.
However there was a point where I was able to ping outside through hyperterminal, not through any internal host. So I was playing around with it and now even I cannot ping outside through hyperterminal, unfortunately I did not backup the config at the time I was able to ping.

One more thing when I ping through any internal host, I can see in the hyperterminal log says denied by one of the rule.
Many thanks for your reply.
