Hello guys,
It's my first post here

I want to ask something. I'm using a D-Link router with all security options enabled (SPI mode, Block ping, DoS protection and unpnp option disabled). I'm using also COMODO Firewall Pro 2.4.
I tested my ports using grc.com and all were stealth, except the following ports range: from 65460 to 65535. For example, if I test port 65459 and low ports numbers, all are stealth, but from 65460 to 65535 all ports were closed and not stealth as I think. I'm not running any app. that can be used such range of ports. My PC is clean too.
I googled the problem and I found a user that is using d-link router have the same issue. However no solution to the problem.
I tried to make a rule from router and also COMODO to block all communications in this range and no good result, still closed.
I want to stealth these ports.
Anybody have an idea of how can I do that?

Thanks very much.
