WebProxy and HOTSPOT

Hi guys,

We have two ISPs as follows:
ISP1: Gateway:192.168.1.1/24
ISP2: Gateway:10.20.16.1/24 (with parent proxy 10.12.0.32:80)

And we have two LANs as follows:
LAN1: 10.10.10.0
LAN2: 100.100.100.0

We are thinking about using mikrotik RB2011iL as a web proxy for LAN2 and a HOTSPOT Server for LAN1 at the same time. Is that possible?

Can you guys help me with that?

Guys?
