Hi,There is a very long story behind this, but ultimately what I need to achieve is the following:I have an 831 router sat on a LAN. It receives its eth1 (outside) address by DHCP. I also want to pick up a second DHCP address that can be used for hid...
Hi,Although I've managed to set up an 837 router to do what I need (VPN/NAT/PAT), I'm a bit confused by the interfaces. My understanding is that the layer 1 settings such as speed / duplex are done on the fastethernet 1-4 interfaces, and the layer 3 ...

It might be worth clearing the 4500's ARP table the next time it stops working to see if that makes any difference... also it would be interesting to see if you cleared the CAM table whether that would help & see if your host MAC is actually in the t...

Hi,There is no vlan database in an 837:Router#vlan database ^% Invalid input detected at '^' marker.Router#show vlan ^% Invalid input detected at '^' marker.Router#conf tEnter configuration commands, one per line. End with CNTL/Z....
