Running the R7000 with R7000_378.55_2 works as expected: Enabling IPTraffic(per IP monitoring) will automatically disable HW acceleration (as reported on the Tools->SysInfo tab). Router seems to be stable without any issues. Running the R7000 with R7000_378.56_2 has problems: Enabling IPTraffic(per IP monitoring) doesn't automatically disable HW acceleration (as reported on the Tools->SysInfo tab). HW acceleration manually disabled (LAN->Switch Control->NAT Acceleration), since per IP monitoring doesn't work with HW acceleration enabled. Router seems to be stable, but ~24 hours after setup DHCP server stops handing out addresses, and DNS server stops resolving names on all interfaces wired/2.4GHz/5GHz. Using self assigned addresses can still talk to other devices on the network, and the internet. (so routing and NAT seem to be working, just DHCP and DNS are having problems). Rebooting the router, re-configuring/restarting DHCP doesn't solve the issue, only fix I was able to find was a factory reset. Running the R7000 with R7000_380.57 has problems: Enabling IPTraffic(per IP monitoring) locks the router up into an infinite reboot loop (if HW acceleration is enabled), only way I found out of it was a 30-30-30 reset. HW acceleration manually disabled allows enabling IPTraffic(per IP monitoring). However as soon as HW acceleration is disabled, the 2.4GHz interface starts having problems. Clients trying to connect have issues getting a DHCP address. If an address ever does get assigned, then DNS doesn't generally resolve. Trying to browse other network devices by IP address works occasionally, but generally times out. It acts like the 2.4GHz interface is actually working, it's just really, really, really, slow. As soon as HW acceleration is re-enabled (as long as IPTraffic is disabled first) the 2.4GHz interface comes right back up. (the problem happens with HW acceleration disabled, regardless of the state of IPTraffic) When HW acceleration is disabled and the 2.4GHz interface is having problems, the wired and 5GHz interfaces seem to work without any issues. I noticed in the changelog for Asuswrt-merlin 380.57 a note about fixing CTF not automatically disabled when enabling IPTraffic, is it possible that fix broke something when the code was ported to XWRT-Vortex?
