I want to permit several VLAN reach internet but can't with the setup (maybe poorly!) I designed. Here goes...
I have 3 VLANs to do InterVLAN routing in a switch Layer 3 and for reach the internet with gateway. My problem is the L3 switch that don't route to a gateway and do it to another. Here are some o the configs (try to minimize not to give you all much trouble!):
set system mode router queues-mode 4 ...
interface vlan 100 name FORMACAO ip address 192.168.100.50 255.255.255.0 ip dhcp relay enable ! interface vlan 110 name OPERACOES ip address 192.168.110.50 255.255.255.0 ip dhcp relay enable ! interface vlan 120 name SERVIDORES ip address 192.168.200.50 255.255.255.0
The default gateway 172.30.1.254 is on "gigabitethernet1/1/18" and if I change to "ip default-gateway 192.168.200.254" all works fine (port "gigabitethernet1/1/48" ).
Some more info within switch:

but if I change to "ip default-gateway 192.168.200.254" all works fine!

To my knowledge all should worked but...
