Hello,

Can anyone make any recommendations as to how I can whitelist a SMTP Server behind the TL-R600VPN v2 Router? Due to high traffic, its IP sometimes ends up in the "Blocked DoS Host List". Once this happens it goes on to cause an E-Mail Outage. Can anyone advise on how this can be prevented without having to give up the SPI Firewall or other nifty features of the R600VPN v2? Thanks in advance!

I have the same issue.  My wife's chromebook keeps getting put in the "Blocked DOS Host List" on my Guest WiFi network.  Please let me know if you were able to find a fix for this.

I think you can increase the Flood Packets Threshold to make your traffic pass. It seems that has not settings like whitelist.

@Andone  Thanks!  I ended up just turning off DoS Protection.  Was too much of a headache and the CPU use was 70% to 80% as well.
