Re: Ip Filter Rules appear magicaly

thank you for your quick reply, well yes as a mater of fact I recognize those ips involved they are valid IPs. The rules involve allowing UDP packages to various ports for instance here are a couple rules:
2028 P,E,N permit in UDP any WAN Interface any any any any WAN Interface 192.168. 2. 48 host = 8941 no
2030 P,E,N permit in UDP any WAN Interface any any any any WAN Interface 192.168. 9.113 host = 14200 no
I didn't know the rules could be created on the fly, I supposed that only the administrator could add or edit rules, but you were correct, uPNP was enabled, I've just disabled it to see if that corrects the problem.

The purpose of uPNP is to open and forward ports automatically on the fly based on what client applications on your LAN need in order to work.

The upside is that this happens automatically and you don't have to set the rules up by hand. For apps that need to have random, not possible to identify in advance ports opened, this can make the difference between an app working or not working. I believe this is "better" than manually opening large ranges of ports to accommodate apps.

The downside is, that since you didn't set these rules up, they can become questionable once discovered, as has happened to you.

Until now, I didn't know what difference Upnp would have in my network, now I know. Thank you very much.

Yer welcome.
