Shibby 114 on RT-N66U - K26RT-AC or K26RT-N branch for bcm_nat?

    Hi
    Having just been upgraded to 200mbit I found the note about bcm_nat interesting and wanted to give it a shot. Since the changelog says "tomato-shibby-RT-N will not continue, Please use RT-AC branch", I figured that meant I should install the build in the K26RT-AC folder for my RT-N66U.

    So I did, and then tried modprobe bcm_nat and it tells me that the module cannot be found. Since the notes on that module say it's not available in the RC-AC branch, I'm now a bit confused or perhaps I'm just misunderstanding the changelogs. The way I read it, future RT-N builds are based on the RT-AC branch, but that would mean we can never use bcm_nat. Or should I just install the build from the K26RT-N branch and it's just the branch names that gave me the wrong idea?

    Oh, also, VLAN order in tomato-RT-N66U_RT-AC6x--114-AIO-64K.trx is inversed versus the GUI - I had port 4 mapped to LAN, and then suddenly my entire network was directly in my provider's network as setting port 4 to be part of the WAN bridge actually moved port 1 (both labeled so on the router and in the overview page) to the WAN bridge. Now that I reverted that and moved port 1 over to WAN, things are as they should. So it seems the overview is okay, but for VLAN, things need to be inverted.

    I was on the K26RT-N branch previously (using build 111 iirc) where port mapping for the RT-N66U was correct.

    this information is only for developers! I merged sources of RT-N to RT-AC branch, thats all. If someone want to compile his own firmware based on my, then we have to download tomato-shibby-RT-AC branch, because tomato-shibby-RT-N branch will not be continued.

    You still can use RT-N firmwares if you dont want use newer RT-AC. Just checkout K26RT-N directory.
    On RT-N66U you can install 3 firmwares at the moment:
    1) K26RT-N - old, good firmware with old good wireless driver and bcm_nat module included
    2) K26RT-N-NEWDRIVER - same as first but with newer wireless driver. Check testing directory
    3) K26RT-AC - this is the newest sources with SDK6 (wireless 6-series). This driver is faster, more stable and free of connection issue but this firmware is not compatible with bcm_nat at the moment.

    Just make a choice ;)
    Best Regards.

    Thanks
    I guess I'll give the trusted old version a shot and check the effects of bcm_nat (I do hit the hard limit of my router when I try to max out my line). Should I do the whole "full nvram erase after flash" procedure even for the sidegrade?

    you always should erase nvram after change software.

    will this affect the linksys e-series? Currently using the linksys e3200?

    modprobe bcm_nat on AC66U with Version 114 not working, you write it. Possible to get working it on the AC-Branches?

    May I restore configuration file that backuped from RT-N branch v112 to RT-AC branch v114 firmware ?
    Will this cause problems?

    This will cause Problems - dont do that. Flash back to v112, open all Tabs in your browser... Flash in a new tab v114 and do copy&paste to new v114 firmware

    Or use RoboForm. I save settings on each page separately, and I can have it input them with one or two clicks.

    @shibby: the K26RT-N version also has the ports inverted in the VLAN page

    Which script should an automatic launch of this module go into?

    @everyone: And as for the backup/restore discussion: maybe we should put up a bounty so that a decent backup/restore can be implemented. Perhaps with an option to store only basic properties that are present in the different builds, plus a full option. It would of course also require those that write mods to be mindful about their usage of nvram variables.

    Is there any upgrade where not erasing the nvram and just restoring the config is OK?
    I'm running 102 Mega-VPN-64K on my n66u, would like to finally get off my butt and flash to 114, but I want to preserve all my custom QoS rules. I noticed there's no Mega-VPN 114 for n66u 64k?
