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.

Same problem with 6.3.0r03 firmware –  catfish Oct 14 '10 at 21:24

Figured out the issue. I had to enable Source Nat on the Wifi-to-Untrust policy. I'm not sure why it's needed (the default policy for Trust-to-Untrust doesn't have it). You enable the option in the advanced section of the policy or change the line posted above:

set policy id 2 from "Wifi" to "Untrust"  "Any" "Any" "ANY" permit log

to:

set policy id 2 from "Wifi" to "Untrust"  "Any" "Any" "ANY" nat src permit log

There may be an implied trust to untrust nat or it might be included automatically via a checkbox on the untrust interface? –  SpacemanSpiff Mar 30 '12 at 0:17
