hi  my office computer ip is 192.168.2.5 

i install a remote soft (remote anywhere) on this computer  open -ports 5555

when i at home                    i want to remote access this computer   with port  5555

i've used other routers (not cisco)      what i do

is this possible ? is this safe?h

Hi,

of course this is possible but we need your running-config to try help you further.

I would rather use a VPN to access this computer( Remote access VPN with RDP for example).

Regards.
