Re: [SunRay-Users] Sunray is dropping VPN connection
It's possible your DNS issue is related to DNS helper schemes that most ISPs now turn on by default. I believe Verizon calls it DNS Assistance; they should have directions on how to disable it.

Re: [SunRay-Users] Sunray is dropping VPN connection (Steven Gelsie)
I'm using DHCP option 49 to specify the SRS and option 66 to specify the firmware server. I wouldn't think that would be the source of your problem, though: if DNS resolution failed, I would think that the entire VPN connection would fail, not that it would initially succeed and then drop off some random time later.
