Fortigate 100a site-to-site VPN

Hello,help me please.

How to set up the VPN tunnel on fortigate 100a?

hi,

that depends on the version of FortiOS that you're using.

The procedure itself is well documented in the "FortiOS Handbook", chapter "VPN".

One advice: if possible (FOS > 4.x), use "Interface Mode" when creating phase1. Much easier to set up and debug.

i use fortios v4.0,build0694

I want to create a vpn tunnel between fortigate 100a(Firmware Version v4.0,build0694) and fortigate 80c (Firmware Version v5.2.10,build742)

On the 100A, can you check the "Interface mode" option in VPN>IPsec>Phase1?
