I really need some help trying to figure some "basic" routing. My brain is fried from being sick for a week and I'm not thinking clearly.

Picture below describes my "setup". I'm trying to accomplish routing a user from their workstation to the Juniper SSG520 and then "OUT" through the internet connection. I can't move the connection as it is physically located where the user's switch is.

Here's what I CAN do at this point:

• I can ping from the Juniper SSG520 eth3/3 to 6x.xxx.253.116 from 6x.xxx.253.114
• I can ping from the x450 in the top right to 6x.xxx.253.112 from 6x.xxx.253.116

What I CANNOT DO:

• I cannot ping from the SSG520 eth3/3 to 6x.xxx.253.112 from 6x.xxx.253.114 (basically from the Juniper box to the gateway.

I've tried changing port 1 in the x450 VLAN 666 as tagged but when I do that then I can't even ping from the Juniper SSG520 eth3/3 to the VLAN on the x450 (6x.xxx.253.116).

I need to route traffic out the eth3/3 interface on the SSG520 THROUGH the 2 x450 Switches and out the internet connection. The caveat is that the 2 x450 switches are connected via fiber over distance and have tagged VLANs in them for the routing.

Thoughts?
