Juniper SSG-5 subinterface vlan routing to the internet
- by catfish
I'm unable to get a brand new Juniper SSG-5 with latest 6.3.0r05 firmware routing to the internet from a subinterface I created on bgroup0 setup as vlan2 (bgroup0.1 on "wifi" zone). When connected on the default vlan it gets on the internet just fine.
When I switch to vlan2 I'm unable to get to the internet. I am able to get the correct ip address (10.150.0.0/24) from dhcp, able to get to the juniper management page, etc but nothing past the firewall, can't ping 4.2.2.2 or the internet gateway. Even setting up logging on the wifi-to-untrust policy and it does shows the attempts (it's it's timeouts).
172.31.16.0/24 is the untrusted lan, it's already nat'ed but works fine for testing. Can ping this ip from the default vlan but not from vlan2
192.168.1.0/24 is the trusted main lan
10.150.0.0/24 is the wifi isolated lan on vlan2
The idea is to setup an AP with lan and guest access (AP supports multiple ssid's on different vlans). I know I can setup the juniper to use different ports for the wifi lan and use their procurve switch to do the vlan separation, but I never used vlan'ing on a Juniper firewall and I would like to try it out this way.
