Same subnet WAN issue

Hi, ive got a little problem with new installed RB2011il-in, last time i changed my internet speed from 60 to 250Mb, but when i get new router( working as bridge for now (UPC Ubee) ) the DHCP gives me another WAN address ( 89.68.162.81). Friend with same WAN subnet ( 89.68.162.182) cannot connect to my ts3/http server or loosing much packets. everyone else connecting without any problems. the problem does not appear when server is connected to ubee router. Any idea how to solve this problem?

Hi,

Did you do port forwarding for you http server and ts server on the mikrotik?

It could be that upnp is enabled on your other router that is automaticly mapping the ports for you.

Also, does your 2011 still have the default config on it?

yop, all ports i user are forwarded (thats why anyone else can connect) uPnP is disabled, trying to use default config but issue are not resolved. any other ideas?
