· This article seems to be the reference for IPsec Site-to-Site (route-based) VPN between FortiGate and Cisco Router. This helped me greatly to get a VPN tunnel up between my 2 devices (Fortigate 60C and Cisco 881W). I can ping from the Fortigate LAN to the Cisco LAN however I cannot ping from the Cisco to the Fortigate.
Configuring the FortiGate tunnel phases. In the FortiOS GUI, navigate to VPN >. IPsec > Auto Key (IKE) and select Create Phase 1. Name the tunnel, statically assign the IP . Address of the remote gateway, and set the Local Interface to wan1. Select Preshared Key. for Authentication Method and enter the same preshared key you chose when configuring the Cisco IPsec
IPSec VPN between a FortiGate and a Cisco ASA with multiple subnets. When a Cisco ASA unit has multiple subnets configured, multiple phase 2's must be created on the FortiGate…
· Earlier, I wrote an article showing how to do a VTI (Virtual Tunnel Interface) from a Cisco ASA to a Fortigate Firewall. Today, I will cover a route-based VPN with a Cisco Router instead of a Cisco ASA using VTIs. Where as the ASA only supports BGP with its VTI implementation, the router is a bit more flexible and allows for OSPF.
There is not any configured NAT in the Cisco router or Fortigate Firewall and the only access list is defined on the cisco R1 is 101 access list, which is: Access-list:101 permit ip 10.0.0.0 0.0.0.255 10.10.10.0 0.0.0.255. the result of the command u mentioned is: R1#sh crypto ipsec sa peer 192.168.43.75. interface: FastEthernet0/0
FortiGate Antivirus Firewall to Cisco Router IPSec VPN Interoperability Technical Note Document Version: Version 1 Publication Date: 18 December 2003 Description: Describes the CLI commands used to set up site-to-site and hub-and-spoke IPSec VPN tunnels between FortiGate firewalls a nd Cisco routers. Provides configuration examples for four ...
This configuration example is a basic VPN setup between a FortiGate unit and a Cisco router, using a Virtual Tunnel Interface (VTI) on the Cisco router. The IPsec configuration is only using a Pre-Shared Key for security. XAUTH or Certificates should be considered for an added level of security. Only the relevant configuration has been included.
· We, me and FTNT TAC guy, concluded enabling "mode-cfg" is the only option to terminate IKEv2 IPSec VPN from Cisco router w/ static-VTI(SVTI). This would allow FortiGate to reply with "0.0.0.0" to those IP requests and the negotiation would succeed since Cisco would ignore that part.
· Customer had a question about creating a route-based VPN between a Cisco ASA and a Fortigate. Traditionally, the ASA has been a policy-based VPN which in my case, is extremely outdated. With Route-Based VPNs, you have far more functionality such as dynamic routing. In the case of ASA, it only supports BGP across the VPN whereas Fortigate can do BGP and OSPF. In this article, I will …
