No the 254 is my rounter and yes I have it connect to a DSL router. And my server is connected to a switch running a vlan and that vlan is connected to the router.i can ping the server with ease but it's still haveing the problem.
Then you should do as I suggested. Use that IP of your router. But know as you mentioned a VLAN involved I can only repeat my comment from above: As you did not wrote anything about your network setup everything here is a wild guess.
It might work or it might not, as long you don't describe the setup of your net nobody will be able to help.

I am having the same issue with not being able to connect to the update server. However, I can send a test email and can also ping the update server.
