Hands-On 1.Publish Web Server that located in LAN side 2.WAN Load Sharing 3.IPsec Hub and Spoke

Hands-On 1 Publish Web Server that located in LAN side From DFL-1600 LAN user can access both DFL-210 and DFL-860 web server using Public IP and Each LAN Users of each DFL can access their own web server using their own public IP

Hands-On 1 Set WAN IP, WAN Subnet, WAN Gateway and assign one object for Web Server

Hands-On 1 Add SAT Rule

Hands-On 1 Add Allow Rule

Hands-On 1 Add NAT for LAN traffic Rule

Hands-On 1 Enable Log for each Rule, for troubleshooting purpose

Hands-On 1 Review all IP Rule Why do we must put LAN_to_WAN rule between SAT and Allow?

Hands-On 1 PC 1 : LAN IP : WAN IP : Web Server : PC 1 open web server using Public IP :1050  :80 Firewall translate it to :1050  :80 Web Server reply it directly to PC :80  :1050 Reply packet will never arrive, because PC 1 expect reply packet come from and not from PC 1 open web server using Public IP :1050  :80 Firewall translate it and doing NAT here :35879  :80 Web Server reply it to Firewall first :80  :35879 Packet send back to PC1 and restore both address translation :80  :1050 Reply packet will arrive at PC 1 as expected

Hands-On 2 WAN Load Sharing Http Traffic goes through WAN 1 Telnet Traffic goes through WAN 2

Hands-On 2 Create object (IP, Subnet and Gateway) for both WAN

Hands-On 2 Make sure, there is no default gateway for both WAN interface

Hands-On 2 Add route for WAN1 with metric 10

Hands-On 2 Add another routing table Add route for WAN 2 with metric 0

Hands-On 2 Add routing rule for telnet traffic

Hands-On 2 Add IP Rules like this below :

Enable Log for each Rule, for troubleshooting purpose Hands-On 2

Hands-On 3 IPsec Hub and Spoke

Hands-On 3 Spoke Surabaya Local Net : /24 Remote Net : /24 (Hub Jakarta) and /24 (Spoke Bandung) Remote Gateway : (Hub Jakarta WAN) Create Address Book like this below :

Hands-On 3 Create Authentication Object, for example :

Hands-On 3 Add default gateway to WAN interface

Hands-On 3 Create IPsec for tunneling to Jakarta / Bandung

Hands-On 3 Create Interface Group like this below :

Hands-On 3 Create IP Rule for tunnel and put it on the top :
