Hi everyone,

I just uploaded release 3.0.0.4.270.25 to Mediafire. (all three regular builds - the experimental builds will be uploaded later once they're compiled).

UPDATE: 3.0.0.4.270.25b was uploaded, fixing the OpenVPN client routing and the DHCP logging options.

The highlights of this new release:

  • NFS Export: You can now export USB directories over NFS the same way you can export SMB shares. Go to USB Application -> Servers Center -> NFS Exports to enable this, and export USB directories.
  • Entware setup script: This script written by ryzhov_al will make it simpler for you to setup and install Entware on your router. Just connect to SSH, and run "entware-setup.sh". Remember that you need to have JFFS enabled first (a later release of that script will let you do this from within the setup script).
  • More OpenVPN performance boost: the latest optimizations increased OpenVPN performance by as much as 10% here (tested by running iperf through an OpenVPN tunnel).
  • Relaxed DHCP queries on WAN: The DHCP client will be more relaxed, sending DHCP discovery packets only every two minutes instead of 20 seconds. While it might make it longer for your router to acquire a WAN lease, it will also ensure that ISPs with strict policies (such as Charter) won't blacklist you anymore after your router and modem recover from a power failure.
  • RT-AC66U driver reverted to build 220: The build 270 driver generated issues for a small portion of users, so it was reverted back to the build 220 version. RT-N16 and RT-N66U both keep the build 270 driver release.
  • More custom config and user scripts: New scripts/configs for DHCP events (WAN only), local user/passwd files, etc...
  • Another batch of bugfixes: firewall will no longer allow WAN packets with a LAN destination, a very old WOL target list corruption bug was finally tracked down and fixed, and more IE-specific bugfixes.

NOTE: If you haven't seen the warning in the README and on the Firmware Upgrade page yet: don't forget that your JFFS partition is NEVER guaranteed to survive a firmware flash! This new release is a bit larger than previous firmwares due to the OpenVPN optimizations, so that increases the chances of your JFFS content getting overwritten. So make sure you always keep a backup of your JFFS partition!

As usual, the complete change list can be found on my website.

See the sticky post in this forum for all pertinent links.

What's coming next:

Build 25 completes the planned internal service updates, with dnsmasq being also updated to the latest release. The next build should see fewer major changes like the last few builds did, and should return to the usual minor changes of past versions.

I currently don't have anything specific planned yet for build 26, so I'll probably just take a breather here (past few weeks have been QUITE busy with all those major changes, plus some personal stuff that hit me a few weeks ago), and keep an eye for bug reports and possibly a new Asus release for now. So expect development to be a bit slower in the coming weeks.

Thanks for the latest release.

For the first time I've had issues after an upgrade, lost internet access for a while untill I found out that it is now necessary to have the default gateway address fill out on the Advanced_DHCP_Content.asp tab, had it empty up till now, probably a DNSmasq thing in newer releases.
 
my gateway is empty?? what should i put in? maybe this is why openvpn broke.

My default gateway is empty and I have no issue here.

Keep in mind that it can take a bit longer now (up to 2-3 mins in some case - for me it's still almost instantaneous) before the WAN interface gets a new DHCP lease from your ISP if it's slow to answer to requests for new leases.

Doubt it's related. The default gateway is typically your router's IP.
 
Hmmm might give this a try since the 2.4Ghz never worked for me.
Fingers crossed. Can I update over WiFi?
 
Something going on with the DHCP server, my clients are doing dhcp requests every five minutes and the lease is setup for 1 day.

Is that wifi client asking for new DHCP requests ? If then check you wifi password.
If that is wrong that can happend.

No, its all clients; wired and wireless. An no, the wireless clients have the correct password. Like I mentioned, they are getting their lease and its set for 1 day, they are just renewing it every 5 minutes for some unknown reason. I swithed back to .24 and its fine again.
 
dnsmasq

There's definitely something wrong with DHCP in .25. I wasn't getting any DHCP leases on LAN after upgrade to .25. Dnsmasq was not running and syslog contained:
Code:
Jan  1 01:00:10 dnsmasq[518]: extraneous parameter at line 17 of /etc/dnsmasq.conf
Jan  1 01:00:10 dnsmasq[518]: FAILED to start up
Line 17 in dnsmasq.conf was:
Code:
log-dhcp=none
Switching 'Log DHCP queries' at Advanced_DHCP_Content.asp from No to Yes removed that line from the config file and DHCP started to work again.

That was probably my problem also.

After going back and looking over the router log, it was a DHCP problem, all clients weren't getting an address.

I enabled the DHCP logging option and filled out the default gateway and it started working, that made me think the empty gateway box was the culprit :eek:
 
something up with DHCP, I was just tinkering and disabled DHCP logging and DHCP this disables DHCP completely. Not sure if this was the case with 270.24 or not
 
I forgot to reapply a dnsmasq patch that added that option after I updated it to 2.65.

For now do not disable DHCP logging to ensure this option does not get set. I'll try to have a 25b release out sometime during the weekend with the patch reapplied.

Merlin great job on this firmware! Has asus or jj said anything about the new radios?

openvpn not working as before

Hello,

my openvpn is not working as before. I have the exact same settings, I got it to selectively route, but anything going through the vpn is not working. Anything going to the ISP is fine. I have the exact same settings.

Quick follow up.. I just reverted back to .24 with the EXACT same settings and it is working fine now.

Let me know what you need for me to help you!
 
Just signed up to say thank you, Merlin, for the firmware. I've gotten much more functionality out of my N66U due to your work. Much appreciated. :)

Quick question about this latest firmware; when I SSH in and run entware-setup.sh (I'm trying to get router-level adblock going), I get an error that states "no ext2/ext3 partition available. exiting..." I've enabled jffs and jffs partitioning upon boot and power cycled my router. I have no experience whatsoever with SSH, privoxy, etc, and have no idea how to proceed. What do I need to do?

Edit: Fixed my own problem. Had to format my USB stick in ext3 format. Took forever to find a Windows utility that supports ext3.

Edit 2: Followed the steps here, but ad blocking doesn't work...

I asked my contact last week, and he didn't have any new info for me yet. However Asus did release a beta version targeted at users having issues with the XBox, which seems to take care of that particular issue.
