So we need to create a policy to allow traffic to go back and forth between the LAN and VPN zones. 5.2.4.Create policy to allow traffic between 2 zones LAN and VPN.īy default, the firewall will block all traffic between zones. Now the circle icon in the Active column turns green, which means that the connection has been successfully turned on. However, this connection is still not enabled, to turn it on, click the circle icon in the Active column and click OK. Gateway address: Enter Palo Alto firewall’s WAN IP as 192.168.2.115.Īfter clicking Save, the IPSec connection will be created as shown below.In Gateway settings we configure the following parameters: Repeat preshared key: re-enter Preshared key.
Authentication type: select Preshared key. Policy: select VPN_S2S_PaloAlto from drop-down list. In Encryption we configure with the following parameters: In General we configure with the following parameters: To create go to CONFIGURE > VPN > IPSec connections > click Add. To create IPSec policies go to CONFIGURE > VPN > IPSec policies > Click Add.Ĭreate an IPSec policy with the following parameters.Ĭlick Save. IP address*: 172.16.16.0 Subnet /24īecause this is an IPSec VPN connection between two different devices, we need to create a common IPSec policy for both devices. Similar to the above steps, we will create a profile for the Remote subnet according to the following parameters: 
To create, go to SYSTEM > Hosts and Services > IP Host > click Add.Ĭreate a profile for the Local subnet with the following parameters: We will create profiles for Local and Remote subnet. 5.2.Sophos Firewall 2 5.2.1.Create profiles for Local and Remote subnet The last step is to review the previously selected options, if you have selected the correct one, click Save and finish to complete. In External source networks or devices, keep the Any option and click Next. In Service, click Add new item and select IPSec S2S VPN profile. In Public IP address check Select public ip address or WAN interface and select #Port 2 – 192.168.2.111 from the drop-down list.
In the Internal server IP address we tick Select IP host and select Sophos Firewall 2 – 10.145.41.50 from the drop-down list. Īfter clicking on Server access assistant a configuration panel pops up. To NAT we go to PROTECT > Rules and policies > Add firewall rule > Server access assistant.
IP address*: Enter Sophos Firewall 2’s WAN IP as 10,145.41.50.ĥ.1.3.Implement NAT IP WAN of Sophos Firewall 2 with IPSec service to the internet. To create go to SYSTEM > Hosts and services > IP Host > Click Add. To create, go to SYSTEM > Hosts and services > Services > click Add.ĥ.1.2.Create a profile for Sophos Firewall’s WAN IP 2. We need to create profiles for these 2 services. The IPSec VPN Site to site connection will use the UDP 500 and UDP 4500 ports. Enable PING and HTTPS services on VPN zone. Create policy to allow traffic between 2 zones LAN and VPN. Create profiles for Local and Remote subnet. Implement NAT IP WAN of Sophos Firewall 2 with IPSec service to internet. Create Profile for Sophos Firewall 2’s WAN IP. Create a profile for the IPSec service. The LAN is configured at ethernet1/2 port with IP 172.16.16.16/24 and has DHCP configured to allocate IPs to connected devices.īased on the above diagram, we will configure IPSec VPN Site to site between Sophos Firewall 2 device at Head Office site and Palo Alto Firewall 3 device at Branch Office site so that both LANs of 2 sites can communicate with each other. The internet connection is connected at ethernet port1/1 of Palo Alto firewall device with IP 192.168.2.115. Sophos Firewall 2’s LAN is configured at Port 1 with IP 10.146.41.1/24 and has DHCP configured. At Sophos Firewall 2 WAN port will be Port 2 and it will be connected to Port 1 of Sophos Firewall 1, Port 2 on Sophos Firewall 2 is set static IP as 10,145.41.50/24. The LAN network of the Sophos Firewall 1 device is configured at Port 1 with IP 10.145.41.1/24 and has DHCP configured to allocate to devices connected to it. The internet connection is connected at Port 2 of Sophos Firewall 1 device with IP 192.168.2.111. At the head office site we will have an external and internal firewall model with 2 devices Sophos Firewall 1 is the external firewall and Sophos Firewall 2 is the internal firewall. #Palo alto networks vpn udp how to
In this article, techbast will show you how to configure IPSec VPN Site to site between Sophos Firewall device and Palo Alto with Sophos device behind another Sophos Firewall device.
