XGS2210-52 VLAN to internet

Hi everyone;
i have an issue with intra vlan routing; this is my scenario:
USG110 (P1-2:wan, P4:vlan1 192.168.1.251)
XGS2210-52 (vlan1  interface ip 192.168.1.250; vlan2 int. ip 192.168.2.250; vlan3 int. ip 192.168.3.250... etc...)
default GW 192.168.1.251.

Each client on vlans 2/3/etc... is configured with respective vlan interface ip as gateway.
Intra vlan traffic is ok, but i can't ping the external GW 192.168.1.251.

If USG is used as gateway by clients (adding Vlans ip 192.168.2/3.251 on P4 port and configuring related policies) everything works fine.

But i don't want to use USG as vlan router... (it's a bottleneck when i move TB among vlans).

Additional configuration are required on XGS / USG ?

Thanks in advance

    Hi @Lorenzo_CRC_Sistemi

    Welcome to Zyxel community!

    Your configuration on XGS2210 is just fine.
    The problem is there are no static route rules on your USG to "route" traffic back to clients.

    Please go to web interface of USG: Network -> Routing -> Static Route
    Assign the gateway IP 192.168.1.250 for destination IP 192.168.2.0/24 and 192.168.3.0/24, etc.

    Please be aware that there might be some default interface 192.168.2.1, .3.1, .4.1 on USG. 
    You must change them to other IP to avoid confusion on static route.

    In this way the backward traffic will be forwarded from 192.1.168.1.251 to 192.168.1.250, and then the XGS2210 handles "internal routing" to a specific VLAN interface, and to clients.

    Hopefully it helps.
