Running 1.3 release, but as I said, since the feature first appeared in earlier betas, it failed the same way. And I have reported this before.
Is it related to the NIC? The reason I ask, I just checked about 6 monowall machines all running the 1.3 release for PC-generic and their hardware varies alot (between Intel, 3com, Realtek, Netgear, Linksys, etc.) and none of them had this issue.
They were upgrade straight from 1.2X series.
