= Huawei HG612 PPP/UDP/VPN Bug=

In 2013 we discovered a bug with the HG612 which affects VPNs when the PPP drops. The shot version of the bug is that UDP session, such as a VPN, has problems re-establishing when PPP drops. This is due to the modem blacklisting the packets. More information can be found on these pages:
