Re: Thousands of attempts to port 35825 and 11090

I couldn't find anything on these ports either.  It's possible they're used by a trojan program.

First scan all your machines behind your router for these open ports.  It's possible one of your machines has been 
infected with a trojan, "phoned home", and now the attacker is trying to gain access.
Just to be safe, run a full virus scan and adware/malware scan or your machines.

If these scans come up negative, and you don't have the ports open on any of your machines, then you're probably safe.

How often do these connection attempts occur?

It's most likely an automated process, possibly scanning your entire IP block for infected machines.
