hi! I've a firewall with 4 nic card, 2 of those nics are connected to the public and private dmz respectively. The remaining 2 nics are connected to the public internet and internal lan each.
Nic1 - Public DMZ
Nic2 - Private DMZ
Nic3 - Internet (telco router)
Nic4 - Internal LAN
If' I would to setup a vpn concentrator (for small sites to establish tunnel to it) which itself is a firewall, what's the advantage of having these vpn concentrator on the public/private dmz zone over direct connection to the internal lan? and vise versa? Thanks.
