Since you claim you can't use a VPN then I can't write anything about how to VPN to your home PC.
As to the company resources, I find that when I work for a company, they set this up for us.
I work from home and normally when I travel I have to stop working since I cannot use a VPN nor I can access anything from outside the country, I would like to know if there's a way to connect to my router home from another router outside of the country or state(Since certain states cannot access certain company's resources) and access websites as if I was home
