i am using a demo 7102 procurve router in production. i bought a new one. upgraded it's firmware. copied the config over. swapped the procurve's and it dosn't NAT or send any traffic over the internet. When on the new router i can ping external and internal ip's. i called my isp and they claim that they do not keep track of mac addresses on routers. i am totally stumped! called hp support they got nothing either.
