Need an authentication solution on Cisco ASA 5500

[Jerry 03]

Hello,

In one of my networking classes we working on designing a small data center. First here is the preliminary design:

As you can see in the diagram the networks will be seperated into 4 different VLANs. On the Cisco ASA SSL VPN will be configured so certain end users who login will only be allowed access to certain VLANs based on who they are. We will be running a RADIUS server that the VPN will use.

So an example scenario: end user student in Building 13 Network (VLAN 13) log into the VPN, we only want to give them access to VLAN 15 and no other VLAN. end user instructor on the WLAN network (VLAN 16) log into the VPN and we want to give them access to only management (VLAN 17), Production (VLAN 14) and no other VLAN.

How can this type of authentication/access control be done? Would it be done on the ASA or Layer 3 switch (ACLs)?

the ASA can do ACLs and will probably handle what you need...but i suck at ACLs. suck hard.

maybe have a radius admin group
and the asa can do DHCP, maybe it can assign a subnet/vlan based on radius group? then an acl can restrict traffic from that vpn-admin-subnet to vlan 14 and 17? or the subnets for those vlans basically?

we have an asa/acl wizard at work. i use to think i knew what i was looking at and could at least interpret them while i suck at configuring them, but...i sort of suck at interpreting them sometimes, too.

With SSL VPN, you grant access (via web browser) to devices (usually servers) based on protocol (HTTP/RDP for Windows etc). The connection is safe and secure up until that pint. What you need to be wary of is where the SSL VPN users can hop onto from that device.

Unless you are talking about AnyConnect? That's a different ball-game...

i understand what SSL VPN is and will be using that. We want to prevent users from getting into VLANs they shouldnt be in. like students getting into VLAN 17 the management VLAN.

xSauronx,

that sounds like a very interesting solution, I will do more research into it and see if its possible to implement, thanks.
