FortiGate as SSL VPN Client
Hello,we having trouble with throughput the SSL VPN on WindowsLatency from the client to the Fortigate is about 20ms and bandwidth in Fortigate site is 1Gbps and client site is 100MbbpsFirst, when connecting locally over the internal gigabit network (with near-zero latency), performance easily exceeds about 60Mbps for download on the client. I verified through trace routes, the route table, and Task Manager that tested traffic was indeed flowing through SSL VPN. This tells me that the underlying hardware is capable. However, when testing from off-site (at least 100Mbps and 20ms latency), the performance changes. From the client' s perspective, the download rate through SSL VPN is about 13Mbps and the upload is the problem in that it cannot exceed about 2-3Mbps.It seems that the increased latency is the contributing factor. Given that the SSL VPN uses TCP, my guess is that there' s an issue with TCP window scaling of the SSL VPN connection itself, especially when the client is sending data to the Fortigate.I tried disable all UTM, change IP on wan. wan has no errors, MTU 1500, speed 1GbitFD (fix).Important: If I configured IPsec VPN and test it, throughput from the corporate LAN to the client is over 80Mbps on both sides. And also traffic to the internet (through the Fortigate, no split-tunnel) reaches maximum client line (about 90Mbps).Has anyone else been able to achieve better performance on either Windows SSL VPN clients? Our clients need good throughput in both directions from corporate LAN and Internet-based sources where latency far from zero...My testing has included Windows 7 and Windows 10 Transfer tests included iperf (tcp and udp modes), SMB, FTP, Speedtest.net (and similar tools hosted by the ISP).

Similarly, the Site B FortiGate unit is configured to send packets with destinations on the 10.10.1.0 network through the VPN tunnel to the Site A VPN gateway.In the site-to-site, or gateway-to-gateway VPN shown below, the FortiGate units have static (fixed) IP addresses and either unit can initiate communication.You can also create a VPN tunnel between an individual PC running FortiClient and a FortiGate unit, as shown below. This is commonly referred to as Client-to-Gateway IPsec VPN.VPN tunnel between a FortiClient PC and a FortiGate unitOn the PC, the FortiClient application acts as the local VPN gateway. Packets destined for the office network are encrypted, encapsulated into IPsec packets, and sent through the VPN tunnel to the FortiGate unit. Packets for other destinations are routed to the Internet as usual. IPsec packets arriving through the tunnel are decrypted to recover the original IP packets.Clients, servers, and peersA FortiGate unit in a VPN can have one of the following roles:Server — responds to a request to establish a VPN tunnel.Client — contacts a remote VPN gateway and requests a VPN tunnel.Peer — brings up a VPN tunnel or responds to a request to do so.The site-to-site VPN shown above is a peer-to-peer relationship. Either FortiGate unit VPN gateway can establish the tunnel and initiate communications. The FortiClient-to-FortiGate VPN shown below is a client-server relationship.

SSL VPN Choosing a mode of operation and applying the proper levels of security depends on your specific environment and requirements. In tunnel mode, the SSL VPN client encrypts all traffic from the remote client computer and sends it to the FortiGate through an SSL VPN tunnel over the HTTPS link between the user and the FortiGate. It supports a wide range of applications, and provides a transparent user experience when properly configured. FortiClient might enable a DTLS tunnel that allows the SSL VPN to encrypt traffic using TLS, and uses UDP as the transport layer instead of TCP. This avoids retransmission issues that can occur with TCP-inTCP that result in lower throughput. For information on troubleshooting slow SSL VPN throughput, see Troubleshooting common issues in the FortiOS Administration Guide. Web mode provides clientless network access using a web browser with built-in SSL encryption. It is easier to set up than tunnel mode and does not require that an application be installed on the endpoint, but it has limited application support and requires more resources on the FortiGate. For more information, see SSL VPN best practices in the FortiOS Administration Guide. Starting in 7.6.0, FortiGate models with 2GB of memory no longer support SSL VPN. Fortinet Inc. recommends to use IPsec VPN or other non-VPN secure remote access solutions such as ZTNA and FortiSASE. See SSL VPN to IPsec VPN migration and Non-VPN remote access for more details..

Be a VPN server if it has a dynamically-assigned IP address. VPN clients need to be configured with a static IP address for the server. A FortiGate unit acts as a server only when the remote VPN gateway has a dynamic IP address or is a client-only device or application, such as FortiClient.As a VPN server, a FortiGate unit can also offer automatic configuration for FortiClient PCs. The user needs to know only the IP address of the FortiGate VPN server and a valid user name/password. FortiClient downloads the VPN configuration settings from the FortiGate VPN server. For information about configuring a FortiGate unit as a VPN server, see the FortiClient Administration Guide.EncryptionEncryption mathematically transforms data to appear as meaningless random numbers. The original data is called plaintext and the encrypted data is called ciphertext. The opposite process, called decryption, performs the inverse operation to recover the original plaintext from the ciphertext.The process by which the plaintext is transformed to ciphertext and back again is called an algorithm. All algorithms use a small piece of information, a key, in the arithmetic process of converted plaintext to ciphertext, or vice-versa. IPsec uses symmetrical algorithms, in which the same key is used to both encrypt and decrypt the data. The security of an encryption algorithm is determined by the length of the key that it uses. FortiGate IPsec VPNs offer the following encryption algorithms, in descending order of security:AES–GCM Galois/Counter Mode (GCM), a block cipher mode of operation providing both confidentiality and An exe installer. That's fine, what I've found from the newer exe is that it downloads an MSI to a temp folder, but either way as long as I have an installer I should be good to go. I can't download from the support site since we don't have a contract. We've inherited the old product from a new client unfortunately so need to find a direct 'open' download.If anyone has access, can download, and post a PCloudTransfer link here for me to download it that would be greatly appreciated. Amazing! Thank you so much! Hi @EZadok ,I am glad I could be of assistance to you. If it is helpful, please mark it as a solution.

Using the menu "VPN Location Map" does show me a nice overview of the currently connected VPN connections (IPSEC, SSL VPN).However, the locations of the fortigate are most of the time somewhere in the Gulf of Guniea (0°S, 0°E). The physical location of all our fortigates is configured in FortiCloud (product details) with the address (street, ZIP, town, etc.). I did not find a way to set the device location in the fortigate GUI, nor via CLI. I checked with dia "geoip geoip-query " on each fortigate it's own location and it shows a somewhat accurate location (sometimes off by a lot, based on the ISP).So, I have several questions:How does the fortigate determine it's own location used for the VPN location map? From the location configuration in FortiCloud? (difficult, if not impossible)Via geo-ip query? (most likely)If yes, which IP is used in a milti VDOM environment with several WAN IP's per VDOM?Note: If I use "dia geoip geoip-query , I get the correct location (Berne, Switzerland), yet in the VPM Location Map, the fortigate is located somewhere in Germany.Two examples:fortigate1physical location: Berne, Switzerlandlocation on VPN map: somewhere in southern Germanydia geoip geoip-query: Berne, Switzerlandlocation fortigate 2 (IPSEC) in VPN Location Map: Thun, Switzerlandfortigate2physical location Thun, Switzerlandlocation on VPN map: Gulf of Guineadia geoip geoip-query: Berne, Switzerlandlocation fortigate 1 (IPSEC) in VPN Location Map: Berne, SwitzerlandHow is the location of VPN endpoints (SSL VPN, IPSEC VPN) determined?Looking at the maps on several fortigates with active VPN's, it seems that geo-ip.

And the FortiGate unit on the office private network.Encapsulation makes this possible. IPsec packets pass from one end of the tunnel to the other and contain data packets that are exchanged between the local user and the remote private network. Encryption of the data packets ensures that any third-party who intercepts the IPsec packets can not access the data.Encoded data going through a VPN tunnelYou can create a VPN tunnel between:A PC equipped with the FortiClient application and a FortiGate unitTwo FortiGate unitsThird-party VPN software and a FortiGate unitFor more information on third-party VPN software, refer to the Fortinet Knowledge Base for more information.Tunnel templatesSeveral tunnel templates are available in the IPsec VPN Wizard that cover a variety of different types of IPsec VPN.
