No internet on LAN2 - Zywall USG 20

cpg_juraj

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?

cpg_juraj

Yes of course. That was my intention but I got to testing just last night. All worked great. Thank you PeterUK
