I have been using an RV320 Gigabit Dual WAN VPN Router for several years now in a simple modem->router->switch configuration, and around the start of August I began noticing a few websites began timing out when I tried to access them.
For example, I cannot reach hivelocity.net (a dedicated server host) via HTTP any longer, though I was accessing it regularly before. It responds to ICMP traffic (ping, mtr/traceroute), and using nslookup I can verify DNS is responding properly.
# ping hivelocity.net

Additionally, when I bypass the RV320 and connect directly to the modem I'm able to connect and load sites properly. I have also upgraded the firmware to the latest version, and have attempted both power cycling and a factory reset without success.
Has anyone run into something like this before? Or have any suggestions about how to debug further?
Thank you,
Jeff
