I'm connecting to my remote machine via RealVNC. I'm using Win10 on both pcs. I port-forwarded the right port on my home router (5800) and connecting works great.
The problem is: I can't connect to ANY pc on the remote lan via the viewer. I'll explain this better: connecting to the remote machine with the VNC viewer works, I can see the desktop and do whatever I like, but when opening Chrome or Firefox on the remote machine and trying to navigate to www.google.com, to google's ip directly or even to my home router page (192.168.1.1 - the one where I did the port forwarding), won't work.
Pinging the router works. Navigating to the webserver interface doesn't. Pinging websites works. Navigating via http doesn't.
I tried cleaning arp cache, dns cache flushing, etc.. it seems that as soon as I log out RealVNC the http connections come back to life. I disabled any firewall (except Windows' one).
Any hint on how to debug this?
Edit: I'm also adding the output of a tracert as requested
