SSL-VPN Limitations
Options
We own a USG20-VPN, firmware version v4.33_ABAQ.0 and we are running a SSL_VPN, but is really slow, even with 1 or 2 concurrent users, obviously each with their different credentials.
On a "Single ssl-vpn connection" between a Gigabit-FTTH and a 20Mb/s link, the
maximum download rate is 700MB per Hour, which is approximately
1.5Mb/s: this is almost unusable.
Every alternative remote
connection works fine and faster: Chrome Remote Desktop, Teamviewer,
Anydesk and so on, so it seems a firewall's issue.
- How many concurrent users can, a USG20_VPN, manage without dropping connection or performing poorly?

Hi @TTpD
The default SSL VPN tunnel can establish for 5 tunnels, and it can extend up to 15 tunnels by license.
If you have more throughput requirement in VPN tunnel , or you can consider to deploy L2TP VPN tunnel in your environment instead.

- do you consider 1.5Mb/s a decent performance just for 2 connections? It is quite limiting considering we are not using 5 concurrent connections!
- Is maybe L2tp/Ipsec better performing?
- We do not need more connections, just good speed

I built L2TP VPN tunnel to my USG60W and test performance by speedtest.
I get download/upload= 80/40 Mbps.
The performance is better than SSL VPN tunnel.
