networking - Raspberry Pi server w/out port forwarding -

i remote pi outside home network. problem apartment provides me wireless internet , can't access router enable port-forwarding. there way around this? dynamic dns service perhaps?

i use vnc ssh and/or ftp.

i use team viewer remote station behind nat without activating port forwarding in situation. need create account on team viewer application, , register target station's team viewer account. when away, please make sure open target station's team viewer , able remote target station first login team viewer account. once logged in have list of target station have registered. double click 1 of list , can remote target station.

vnc or ssh not able work behind nat without activating port forwarding because router try open it's own port instead of target station.
