Hi great people,

I have a VPN IPSEC between two beautiful Zyxel firewalls. I have a connection, so that is great! The only problem is, I can't ping to each other. I checked everything but I can't find the issue. Anyone here that can guide me to the right direction or can help me through TeamViewer?

Thanks a lot!

Regards

    Do you mean you cannot ping to Device(Peer USG interface IP) or Remote site lan side host?

    I can't ping to the remote site lan. For example the firewall on the remote site or the printer.

    It looks like the packet is blocked by security policy rule, can you disable both site firewall rule temporarily for testing and try it again?

    The problem was that there was an inactive vpn gateway on the top. After removing it, it worked.
    It's weird, because it was showing inactive. I thought that this will not apply on the rules.

    Zyxel Support helped me on this. Thanks to them!
