I’ve installed a Balance 20 at a customers site who has Cogent as the ISP. Cogent requires the connection to be 100 full duplex to meet their SLA. The Balance 20 is set to 100 Full but will not pass traffic when Cogent sets their port to 100 Full. They have to be on Auto for this to work.
It works just fine if I set a laptop to 100 Full and connect it directly to Cogent’s port.
I’ve just updated the firmware to v6.2.0. I’ve also tried different patch cables. Tech support at the dealer is now saying to try MAC spoofing. It’s a long ride down there and I’d like something a little more substantial to try. Otherwise I’m going to have to replace it with a Sonicwall.
Has anyone seen this behavior?
