I'm looking to host a few workloads for friends. I have an ASA5510 and a 3500 switch. We plan to have a few VLANs behind the switch, all sharing the single internet connection. I was thinking of trunking a port from the ASA to the 3500, configuring sub-interfaces on the ASA for each VLAN and having the switch point to the ASA for default traffic.
My question is, with regards to the routing side, do I assign an IP to the SVI for each VLAN on the switch (i.e. int VLAN20, ip address 192.168.20.1 255.255.255.0) and have a the next hop pointing to the ASA's sub-interface for that VLAN? I guess that would mean i'd need a default route for each VLAN?
What are the suggestions?
