I tried to setup the vpn connection in the latest teddy bear's tomato with vpn. then i found that whenever i want to save a change, the tomato says: "Invalid number. Valid range: -1-2147483647" Then i figure out it is due to the entry "TLS Renegotiation Time", according to the specification, -1 is for default. however, tomato does not take it -- can't save my changes made to other entries. See the attached picture.
