Me and my brother are starting to work at upwork, so we will share the same internet connection to work at our home, I would like to know if there is a problem about sharing the same IP address for two freelancers or we could work with no problems.
It is not a violation to share the same IP address and computer/laptop with more users as long as you don't share your account with another person. Also, it is not a violation to login to your account from the different IP addresses, computers or laptops.
It's important that you don't share your login credentials with anybody and don't log into other users' accounts as it's a serious violation of Upwork ToS. Thank you.
