incoming service from itnernet to specific computer

Hi there,

i have a USG310 and i use it to connect to diffrent locations throu VPN.
What i need is some kind of advice how to set up so that if anyone types in the static ip adress of the router it should be forwarded to a webserver that i have set up. 
example if i write https://44.55.66.77/webserver/login/ everybody from outside should reach this server that is situated in the lan and has ip adress 192.169.0.222 port 80 without affecting the vpn tunnels and the rest of the services

Many greetings and thank you
Marc
