In all cases, I can ping the those hostnames with good response times. I’m under the assumption that if I can ping them, it’s not a routing issue. My next course of action is to remove the Peplink from the equation and hook up a machine directly to the ISP to see if the behavior continues. But as the site is a bit of a drive, I thought I’d ask if anyone had seen an issue similar to this one? I don’t have any firewall rules in place. I had DoS protection and DSL/Cable Optimization turned on. Turning that off makes no difference.
