Hi Sai, Yes, from Internet --> pfSense ----> Netscreen ----> Lan, DMZ,
For DMZ internal server, it is still ok to use static route. the traffic can be routed in only using one layer port mapping from PFSENSE instead of two layer of port mapping, however, for LAN, static route is not recommended because of port mapping is still preference for security concern, please correct me if i am wrong My main concern is , i do have one OPENVPN server (IPCOP)sitting after the netscreen firewall which is using port mapping method, the authentication is taken place after going through the netscreen with allow port 1194, let me explain my existing senario and workflow, from Internet --> pfSense ----> Netscreen ----> Cisco core switch 4507R------>VLAN server farm( IPCOP OPEN VPN), it is how my remote user like senior manager, CEO get access to company resource. below is the option for your review, Solution 1) Actually, i am thinking to replace my netscreen firewall to IPCOP( we called it IPCOP A), and migrate the exisiting OPEN VPN policy from the box to IPCOP A, that would be centralize as whole, with the new workflow, from Internet --> pfSense ----> IPCOP A plus OPEN VPN---------> LAN in multi vlan Solution 2) Alternatively, pfSense ----> Netscreen ----> Cisco core switch--------> VLAN server farm( OPENVPN), but it is require two layer of port mapping. Solution 3) Pfsense-------> Pfsense with OPENVPN-------> LAN in multi vlan if i pick the solution 2, that would be easier for the implementation, i still can sustain the netscreen and OPENVPN box and just concentrate on PFSENSE in front end and port mapping, but, what is the impact of two layer of port mapping, the reason is, migrating OPEN VPN policy and replacing a firewall is a nightmare. now, i am struggling to the implementation of PFSENSE because of the impact reflected to the whole network infracstructure, please advice me if i am wrong, Please let me know if i am confusing you, i can explain it in more detail, Thank you.
