Try emailing support@untangle.com with your UID and enabling remote support in config->system.

I never heard from you and I'm heading out.
I'll check for your email again tomorrow.

Thanks. I'll email them.

Post Mortem: It turns out that CenturyLink somehow messed with the MTU size. Untangle would hang on PMTU discovery. Dirk changed the MTU size to use 1480 and it began to work.

Getting this support on a holiday was unexpected and greatly appreciated. Dirk and his team are awesome! I continue to be a huge fan of Untangle.
