Bogous F5 after they migrated to Linux
The F5 gateway has became incredibly errornous after they migrated from FreeBSD to Linux, so I call this a bad move.
In the Good Old Time(TM), they run FreeBSD on their boxes, and I have never encounted a single problem when doing everyday work. After they migrate to Linux, they start to inject error packets into your connection and therefore, SSH is broken. This is critical for development, IMHO, and prevented us from being able to work.
Either they sentence their Linux to death, or we sentence their device to death!
