Jul 27th, 2008

HI, I would like to get expert consult whether ADSL line (do not have fix IP)can work together 3560 (as L3 routing) to establish an office LAN with few difference Vlan?

Currently my physical connection is

Phone line->ADSL modem->ADSL Router-> Cisco 3560-> PC

I have this problem too.

The ADSL is terminated in the ADSL router so the switch should serve its function as a L3 device hosting multiple Vlans on that office.
