This integer sets how many seconds this Virtual Router will hold received IP fragments while waiting for the remaining fragments needed to reassemble the full packet. An administrator tunes it to balance memory used holding partial packets against tolerance for slow or lossy paths that deliver fragments late. For example, setting csOrionVPNVRouterIpReasmTimeout to 30 seconds on a VR terminating a satellite backup link gives slow-arriving fragments more time before the VR discards the incomplete packet.
