Thanks Grant,
the way i am thinking to do , haven't tried it yet ,
I have the exported rules from the ISS Proventia desktop firewall in excel and in xml format
I will add some rules in the Symantec Firewall console and then export them
Open the export file and will see if they are readable
If they are then i will edit and copy paste all of the stuff from ISS rules in it then import it back.
let see if it works :)
do u know by any chance that if its readable/xml kinda import/export in SEP ? i will check and update in a while...
