Hello folks,
I am planning on replacing old MS ISA server with Sophos UTM and i need advice on few things.
ISA has public dns server running on external ip address, with records for
published smtp and web servers located in internal network.
Can this be done with Sophos UTM, can it be a "real" dns server? And if yes, how?
ISA has one internal adapter, with ip address 192.168.10.1/24
and internal network range of 192.168.10.0-192.168.12.255.
I can not grasp how this network range thing works, but it works..
ISA internal adapter is connected to VLAN 10 on Cisco L3 switch.
Switch has total of 3 VLANs (10,11,12).
VLAN interfaces have ip addresses:
VLAN10 192.168.10.2/24
VLAN11 192.168.11.1/24
VLAN12 192.168.12.1/24
Switch uses ISAs ip 192.168.10.1 as gateway of last resort.
Question is, would it be better to use 3 interfaces on utm and connect each to different VLAN, or to do VLAN tagging on utm, maybe on lag interface?
Or is there a third way to do it?
Kind regards,
MarkoS
