No, btw both of you and your friend's nation can not log in from a same network, it will deem as multi nation. My advice is use your home network so that it will not counted as cheating and you can even trade with your friend.
we do not have the same ip, if we have the same ip we will deem as multi, we only have the same isp. can mod do anyhting for this matter? if nothing can be done, it's alright.
