Hi,

I have successfully configured my zywall to allow ssl vpn users connect remotely.
I granted access to two users and they both connect properly individually.
Problem is that while a user is connected, the other one can't connect (it gets disconnected immediately).
As far as I know usg 20 allows up to 5 ssl users for free.
Is there any kind of limitation on simultaneous access? Or do I have to change something in my configuration?
Thanks!

    Which USG20 that you have? USG20 or USG20-VPN?
    If your model is USG20, then Max. concurrent SSL VPN users is 1.
    You can reference to datasheet of USG20.

    Hi @Zyxel_Stanley
    thank you for your answer, I'm currently using usg20 (non-vpn) so you are right.
    I also have another issue on ssl vpn, I'm able to connect and reach the internal ip address of the zywall but I can't see any other device on the remote lan.
    I assume a policy route is necessary but it's not clear to me how it has to be configured. Could you help me please?

    Please note that I can ping the vpn gateway ip address properly (192.168.200.1). The ssl range I assign is on the same class of the vpn gateway (192.168.200.10-20) while the remote lan is on 192.168.30.0/24.
    Please advice

    Hi @Pabloit

    The function you required should be NetBIOS protocol.

    The NetBIOS over SSL VPN tunnel doesn't supported on USG20.

    Hi @Pabloit

    If you would like to pass Netbios traffic over SSL VPN tunnel, you can consider upgrade to USG20-VPN.
