After updating the firmware of my WRVS4400N from V 2.0.1.3 to 2.0.2.1 all traffic was blocked for all machines, even some not included in the list of PCs.
As the log was showing that all traffic was blocked by access policies, I disabled the only rule I had (blocking access to some sites to some MAC adress list) and everything worked fine.
I tried creating a new, simpler rule but after activation it blocked again all traffic for all the LAN.
After many trials, I decided to roll back to the previous V2.0.1.3 which solved this problem.
But this firmware update included some serious security issues, so I would like to know how to solve it if possible.
Thanks,
Matías.
