Fortigate VPN SSL

Thu Sep 07, 2023 6:49 am

Hello,

It's possible to act the mikrotik routerboard as sll vpn client for fortigate? I have several devices should use ssl vpn from fortigate to access internal resource and i think if the ssl client vpn can be handle using mikrotik so all devices no need to use fortigate vpn client again.

I don't know about SSL-VPN but, since both FortiGate and MikroTik support IPSec tunnels, you could try using that if you have the necessary access to the FortiGate device.

Interesting to see someone else with a similar problem!

As far as I know, Forti SSL VPN is proprietary (not the "standard" one, if there is such a thing). The term SSL VPN mean "encapsulating the data in a TLS session", but the details are often very different (authentication, etc).

A few years ago I can up with a "solution" to allow several hosts on a site to share a single FortiClient VPN. On the Mikrotik I create a IPIP tunnel to a minimalistic Linux VM, that runs the FortiClient Linux (CLI), acting as a router to pass the packets thru the VPN, that is conneted back to the Mikrotik.

Not a "clean" solution, but allows for a seamless use of the single VPN (when the customer dropped PPTP a few years ago).

Since I've switched to a x86 box (R86S) running ROS7, I've contemplating trying to create a container to host the FortiClient (x86 only), and get rid of the Linux VM. There are still a few details to sort, because NAT needs to be done in the container (that has the VPN interface).

So, at this time running a Linux VM sounds like the only solution. But if you already have VMs, not a bad idea, as the result is seamless (may need some DNS magic too).
