==PPP restart = broken VPNs==
====Issue Description====
Last year we had an problem with Huawei FTTC modems, the standard ones that Openreach supply The bug appears to be that the modem manages to "blacklist" some UDP packets after a PPP restart. Typically this affects VPN tunnels. The short term fix is to unplugged and plugged back in!
We now have what looks to be the same fault on the ZyXELs - both on ADSL and VDSL.
The fix in the Huawei modem was relating to an 'acceleration' setting in the modem. Disabling this feature fixed the fault.
For a longer description of the Huawei fault see:
