Routing expert please help. Currently my pc is connected to my router gateway 192.168.24.1
and i have webserver hosted on my pc but when i connected vpn on my pc, and my webserver
no longer reachable on public. Everytime i connected the vpn all traffic is routed to the vpn
tunnel. But i only like to connect one public ip to download file when vpn connected.
Can i preserve my default router gatewway 192.168.24.1 and only route the public ip through
tunnel. What can i do to make it work?
Pls some expert help cause i have no knowledge about routing.
