canada – How can I connect my computer DSL overseas without been block it from the company? besides VPN

I need to travel for over a month overseas and I would like to work from there, but my computer is a monitor only and need to be connected to the modem directly. Not sure if the system will block my access since my system and computer or IP address is from Canada.
Anyone knows any device or software to avoid this besides VPN?
I cannot install a VPN on my computer because is restricted somehow.
Hope anyone can guide me.
Thank you!!!
