Connecting Mikrotik Router with users in vlans "cisco switches"

hello all,

I already have 34 VLANs that created on “Cisco Catalyst 3750” Switch, and distrbute by multi “Cisco Catalyst 2960” .

for bandwidth control: I got a MikroTik Router ccr1036
I connect mikrotik to active directory of windows server by radius server for authentication in hotspot.

notice " Accessing the Internet through a proxy in a browser, becuase for university network uses getway that be juniper firewall for multible rule and policy "

My problem is:
1- every users have same mac address " this mac for cisco 3750 L3" Which directs the VLAN to servers and firewalls .

2- so I don’t know how to use the current route the VLANs (CISCO Switch) with Mikrotik Router. or Connecting Mikrotik Router with Cisco Catalyst 3750 .

Or how to be use mikrotik router for distirbute internet by proxy.
any one have idea or solution.
plz help.

Thanks every one .

Anyway, thanks everyone…

After effort and analysis, I found the solution, and of course it is not far from the idea of ​​a proxy.

I connected the Mikrotik to a sub-switch “2960”, which is considered layer 2, and I connected it to the main switch “3750” and the VLANs were read, and from set the IP of each vlan according to its private IP and setup a hotspot for each of them through the port of Switch 3570 which is the trunk through one of Mikrotik’s ports, trunking with the switch 3750 port and allowed all vlans to cross, and authentication via Radius with the active directory of Windows Server also through a Radius port on Mikrotik in the same switch server and Windows server by same Range IP. and then every hotspot server for every vlan has a hotspot with an IP from the same range IP of vlan.
and bandwidth control by queues to ip .

thanks God, the work was done successfully and the read is of each computer according to their own Mac address.

and of course the Connection to any hotspot of vlan, via proxy ..
