I have made a few changes and added a cisco 2811 and a cable modem. i am able to ping out from the 2811 but not the 4507. I can ping the default gateway of 172.16.110.4 but nothing beyond that.5/24 on the switch is the trunk to the router. Router:Val...

Thank you!! You solved a few issues for me. My internet has been running slow when connecting to new sites on each computer. The ARP issue would explain this. My Vlan 30 would not connect to the internet and the access list explains that. So thank yo...
