End user here. Just thought I'd post a few possible bugs I've run into since updating to 3.10.50-1. I'm not exactly sure if these have been reported or are intentional, but I figured it couldn't hurt to post them anyway. 1) When using PPPoE on the outbound interface, traffic skips classification MARKS set by iptables in the QOS_MARK_ge00 chain entirely. This is whilst using simple.qos. Everything is placed in the 1:12 class in HTB in both ingress and egress regardless of rules set. This was tried using 3.10.34-4 and then a fresh install of 3.10.50-1. 2) In 3.10.50-1, whilst running multiple Intermediate Functional Blocks, restarting SQM often has a chance to not close IFBs after the first IFB. i.e Anything after ifb0 has a chance to not close. Cero then creates a new Block(s) after the ones that haven't closed as it believes they are still in use. Doing this enough eventually fills up all available Blocks and then ingress shaping fails to start. Workaround for me has been to SSH in, stop SQM completely, and then start it back up again whenever I change settings as that ensures any lingering IFBs are closed down. Unfortunately, I foolishly forgot to keep any logs using cerostats.sh and no longer have a modem to test PPPoE on; the one I had couldn't hold the DSL line for very long and was subsequently returned. I also ran into something which I thought was Bug #442 after updating to 3.10.50-1. I had moved from 3.10.34-4 using the sysupgrade image. The router seemed to lock up twice within the first 15mins after boot and again after reboot. Only the 2.4Ghz network went nuts while 5Ghz remained fine. Everything on the 2.4Ghz network was still connected, yet nothing on 2.4 could get through - both to the internet and to the router itself. I then decided to do a clean install and haven't run into it since. This is something which has happened to me before on an earlier release and I only ever seem to run into this bug whenever I use a sysupgrade image, or restore my settings from an archive. Something I've noticed is that #442 (or something similar) never seems happen if I do a clean install and rewrite my settings from scratch... Just a thought. I think that's about it. And if anyone's willing to answer this, I know this isn't exactly the place ask this, but, aside from having Cero handle external ICMPs requests, is there any inherent performance/security/bufferbloat benefits from having Cero handle my external ip over a gateway --> router combo? Right now, my setup consist of a gateway and I'm unable to put it in bridge mode. The gateway does NAT, has SPI disabled, and has a static route and DMZ defined towards Cero. Cero is connected to the end of it with Masquerading disabled and the firewall still up. Every device we have runs through Cero. I'd like to know anything at all before I decide to go looking for another dedicated modem, or if I should even bother to go looking in the first place. Hope this helps! —Regards, Richard
