I'm having some trouble after the upgrade to Firmware 4.3.3-6. It's using a relatively complex configuration, so there could easily be one or more settings to blame, but I'll try to keep my questions to the point:
1) VPN connections are unstable, the negotiation succeeds, both sides say the connection is up, but LAN servers still can't be reached remotely sometimes. Now to be honest, this router has never seemed to have rock solid VPN connectivity, but now it seems that all too often the connectivity dies despite the connection still being live (showing connected). Is this a known Firmware issue or are there any particular settings that should be tweeked?
2) What do the log messages shown below mean - what is "error code 10?" I can't imagine a call trace in the logs with a message saying "Badness in local_bh_enable" can indicate anything good... is it benign by any chance or indicative of corrupt firmware/invalid config?
Thank you

4.3.3-6 on my fvs336g-v2 actually borked it, intermittently started blocking traffic (acted like blocking all dns traffic) while showing connected.. had to rma it, got fvw336g-f3 with 4.3.3-6 that acted same way. reverting the V3 to 4.3.3-5 worked fine and was stable. I was not able to get the v2 stable on any firmware after applying 4.3.3-6 to it.
if on 4.3.3-6 may be worth trying 4.3.3-5.
just a thought.
I am not an expert and use mine on very small lan so take the thought with huge grain of salt.
