How do I create a site-to-site IPSec tunnel between Untangle and another device?

IPSec on Untangle should work with any compatible endpoint, but unfortunately Untangle doesn't have the resources to test against all known IPSec devices. Untangle recommends documenting the Phase1/Phase2 settings of the 3rd-party IPSec device then matching those settings on Untangle, which can be entered under the Manual Configuration available in all tunnel configurations. Untangle support has successfully deployed IPSec connections to various models from the following 3rd-party manufacturers:

• Cisco
• Endian
• eSoft
• Firebox
• Fortinet
• Juniper
• M0n0wall
• pfSense
• Sonicwall
• Watchguard
• and many others

To assist with deployment, please feel free to use the attached PDF file to gather the configurations needed from the remote VPN device.
