This switch is behind a Cisco PIX with rules to allow my laptop with a static ip of 131.136.249.140 with some mask and default gateway as mentioned above to access the web. I have a fiber optic cable from the fiber optic tray to a media converter and the ethernet cable from the media converter to the above-mentioned switch. If I plug the ethernet cable from the media converter to the back of my laptop, I am able to go the internet without any problem. However, If I plug the ethernet cable from the media converter to the Cisco switch 2950 and connect my laptop through the switch, I am not able to go to the internet and nslookup does not resolve properly also. Please have a look at the switch configuration. I will appreciate any ideas to solve this problem.
Thanks in advance,
Benchmark.
