Tested it some more, but with load balancing enabled.

It’s almost like clockwork. Performs great for about 1.5-2 hours and then degrades. Seeing this error on the VPN interface (site interfacing with the DSL circuit):

read UDPv4 [EMSGSIZE Path-MTU=1480]: Message too long (code=90)

This error is thrown and shortly after the performance drops for the DSL connection within Zeroshell.

Any advice on MTU settings within Zeroshell? Should I be adjusting the MTU value on the Ethernet interface that’s connected to the DSL router? Everything is set to 1500 by default.
