Hello all,

I have problem with USG 1100 and VPN SSL.

We are allow for RDP for users via VPN SSL. But it's slow and unstable. 

We didn't registered high usage of CPU/RAM etc. all is in normal usage.

Do you know what could be wrong?

We have up to date firmware on Zyxel and Secuextender.

Regards,
Rafał

    Same here.
    My internal network dissapearing from SSL VPN and only UTM reboot helps.

    Can you share more information about SSL VPN session unstable?
    What is your firmware version?

    USG 310
    Firmware version: V4.33(AAPJ.0) / 2019-01-09 09:39:20
    After connection made with secuextender can't ping connected network servers and workstations.
    Remote workers complain on slow connection often. Its good for remote putty console with server but not for working with file transfer or remote desktop on 150/150 stable fiber connection.
    When reboot my device everything starting to work. It happens after few weeks without USG reboot.

    Can't make VPN working without reboot disconnecting all users.

    I have the same problem with them I'm using a ZYWALL 110 with V4.33(AAAA.0) Firmware.
    Speed is slower than 200kb/s most of the time.

    I am on the same firmware version on a USG 110, and also experience slow VPN throughput. Is there a patch available? Checking for an update under Firmware Manager, shows no updates available.
