I have my new service hooked up to my 310, it's a gigabit fibre connection I'm using a media converter to hook up to the 310, authenticate via PPPoE and using a VLAN interface to tag the traffic.
Everything works fine, but my speed tests are inconsistent. Speed swings up and down and usually settles in at 800-850 Mbps at best and sometimes lower (just tested to 750). Direct speed testing with the ISP equipment not involving the Zywall were 1100 Mbps. Which I don't expect through an ethernet interface, obviously, but I should be consistently seeing 900-950 Mbps.
I'm only using the Zywall for SPI, none of the subscription services are active and my rule set is not large or complicated. CPU use during the test runs never goes above 30% so I'm at a loss as to what it might be. Using the same PC on the LAN I'm able to transfer files from NAS at the full gigabit link speed so it's not a cabling issue.
Is the Zywall terrible at PPPoE? Should I stop attempting to implement the vlan tagging on the Zywall and instead do it at my switch?
