Hello.

I am fairly new to zywall. I am trying to enable LAN2 interface on USG 20. LAN1 works great and it is on 192.168.51.x. My intention is to enable LAN2 and separate it from LAN1 as it is going to be a guest internet (wifi). I have enabled the interface, change the subnet to 192.168.2.x, assigned DNS and DHCP pool. While the DHCP does it's job and assignes IP addresses to clients, there is no Internet. Any help is appreciated. Thank you.

    Do you have a firewall policy setup to allow LAN2 to WAN?

    In Network > Routing you may need to make a rule for LAN2 to SNAT to WAN.

    Incoming = Interface

    member = LAN2

    Next hop

    Type = Interface

    Interface = WAN

    Address Translation

    Source Network Address Translation = outgoing-interface

    Hi @cpg_juraj  

    How about test result after added policy route rule?

    Do LAN2 clients are able access to internet?
