I am needing to allow our Symantec AV Server through our ASA 5510 to download updates. I am only wanting to allow the server out to the symantec site(s). I contacted Symantec to get a list of IP Addresses they use for their definition downloads. Symantec indicated they reference a domainname/url and they don't have a list of IP's to give out. They indicated I only need to reference liveupdate.symantec.com in our firewall and it will work. How do I create an access-list rule in the ASA to reference liveupdate.symantec.com?
