I've successfully installed and configured guacamole 1.5.2 in Tomcat 9.0.78 and I can login to the entire system. From guacamole, after I've accessed a remote pc, for example via ssh, in the User -> Settings -> History in the column Remote Host I see the address 0:0:..:1, instead of the real remote address.
Furthermore by checking the Catalina.log, I see that for the user logged, I've two addresses, like for example ..... - User test successfully authenticated from [192.168.15.56,0:0:0:0:0:0:0:1]
My question is, how can I show in the Remote Host the first address instead of the IPv6 loopback address? Is there any particular settings to set in Tomcat?
