HI,

I have a VPS server with fast internet connection.
I would like to configure tor bridge on that machine.

VPS server has configured some services already. If tor bridge service
will run on that machine (IP), will it generate any impact for IP
reputation ? I mean blacklisting.

Greetings

A bridge's IP is not on a public list. So generally running a bridge shouldn't affect your reputation at all.

Average people who don't use tor will not know that you run a bridge on that IP and don't care unless you tell them.
Average people who want to use that bridge will appreciate it.
Other service providers will not know about that fact and probably don't care either unless you tell them, because it doesn't affect their services. Since a bridge is used as a first hop in a tor circuit and not as an exit only other tor relays will receive connections from it.
If your ISP doesn't allow you to run a tor relay but doesn't put too much effort into monitoring your traffic they'll probably not notice that you are running a bridge.
A sensor who tries to block access to the tor network may find out your IP and block access to your other services, too.
If you provide a service that is being sensored in some countries then people from those countries probably won't be able to connect to your bridge either.
