I have a partially working SSLVPN setup between 2 fortinets.
The tunnel itself comes up fine.
What I'd like to be able to do, is route packets from/through the main router, to a subnet that is BEHIND the client.
eg:
desktop -> MainFGT <-VPNSSL <- subFGT = officesubnet
and I want "desktop" and "officesubnet" to be able to communicate.
packet capture on MainFGT says that packets for "officesubnet" enter the virtual
SSL-VPN(ssl.root) interface...
but they dont seem to emerge on the "subFGT" router.
I've tried adding a static route for the subnet to the IP address that subFGT gets assigned for the tunnel..
but the route table always zeros out the Gateway IP to 0.0.0.0
Can anyone help me out with this?

I guess a simple solution would be to change VPN type to a classic Site-to-site tunnel, but I assume that's not possible in your case?
exactly. ipsec is blocked, we have to use sslvpn
Hi @pbrown134 ,
Are you using FortiGate as SSLVPN client, if yes , can you just check and confirm did you configured as below article?
https://docs.fortinet.com/document/fortigate/7.0.0/new-features/508779/fortigate-as-ssl-vpn-client
If this is not the case, can you share relevant routing logs and sniffer and debug flow logs?
routing.. "logs"?

(yes, fortigate as client as i said in my initial post)
Also, that article only refers to setting up the base connectivity. It does not help with routing through the ssl-vpn client, to a network that is specifically behind the client.
I remember we had the same conversation a month or two before. It's not designed to do routing through without NAT. That's why it's NATed in the policy.
If IPsec is blocked you might want to try IPsec over GRE. It might not look inside of the GRE tunnel to block it.

Trying to do business through UAE.
They look for anything that looks like vpn traffic and block it.
So, it HAS to be sslvpn
@Toshi_Esumi Could you help me find the particular prior post you mentioned, please?
It was just "it's not designed to work like you described". So it wouldn't help you.
