Cisco 881 configuration

[adrianbrosz]

Hi,

I have a problem configuring Cisco 881. The network is very simple - on one side router from internet provider, on other side ~50 computers behind NAT.

The link to service provider is properly configured (I can test it form router tools, ping etc., it is visible from Internet), the problem is that none of computers in local network can "see" Internet, and the VOIP system ports are not forwarded to VOIP server.

It seems to be a problem with firewall or ACLs, but I don't use ACLs and firewall is (from my point of view ;-) properly configured.

I would be very grateful if someone look into attached configuration and find errors....

Greetings,

Adrian

Hi,

Is NAT working correctly?  ---> sh ip nat translation when pinging from a host to internet

Are there hits on the good ACL entry  ---> sh access-list after clearing counters

Why are you doing outside NAT? Can you get rid of it and try again.

Is the firewall blocking traffic ---> ip inspect log drop-pkt in global config and enable console logging

Regards.

Alain.

Hi,

there was a problem with NAT - I've deleted "outside NAT", made some changes and it worked :-)

Thanks for your tips.
