VPN Cisco - Fortigate

[jsepulvedasalgado]

Hi, everyone.

I am trying to set an VPN between an Cisco C870 router and a Fortigate firewall.

I configured both devices following the info of the link bellow:

https://kb.fortinet.com/kb/viewAttachment.do?attachID=FortiGate_to_Cisco_Routers_VPN_Interop_Tech_Note_22_Dec_2003.pdf&documentID=10229

But the VPN is not established.

Did anyone have configured VPN between thoose devices before?

According the link info, Do you see any missing details?

Thanks you in advanced.
