I have a Cisco ASA5505 with Security plus license, and there are 3 VLAN configured on the ASA5505.
VLAN3 guest wireless VLAN
Ethernet0/0 access VLAN 2 connected to ISP with static IP address
Ethernet0/1 is trunk port connected to Cisco 2960G. It works great, and inside can access to outside, VPN client from outside can remote access to inside. All my devices are connected to 2960G, and for sure my inside LAN traffic will tied down to 100Mb because the ASA5505 interface is 100Mb. I am thinking to get the Cisco 2821 router and place it between the ASA5505 and 2960G and have 2821 route the traffic at 1Gb connection for inside LAN. I know static route and NAT need to be configure on 2821 as well as configuration change on ASA5505. I do not want to upgrade the ASA5505 to ASA5510 because too much power for home user . Is it possible? If yes could you please shed me the light to make it work? I greatly appreciate your help.
