can somebody explain to me the process of setting up QOS on a watchguard. at present there are 2 sites both with an xtm330. these sites are linked with a fiber lan extension (so effectively 100mbps lan connection). port 0 is for adsl conections, port 1 is lans and port 2 is the link. the main reason for this is to ensure the phone system isnt affected by other network traffic during busy times or when burst large data is transferred.
