I have ACL's on a few internal VLAN's and folks are beginning to require the use of Webex. The website says this:
WebEx services are offered over the following IP ranges:
220.127.116.11 - 18.104.22.168
22.214.171.124 - 126.96.36.199
188.8.131.52 - 184.108.40.206 (Subnet)
Can I use an IP-range command or do I need to list each of these networks individually?
Or for example, just opening a full class B? Would you recommend against this? I can still be more granular on the edge firewall as the ACL's are more flexible. (Also I know the website says it is generally not recommended but it seems they don't change IP's very often.)
Also, do I specify the command with the mask or the wild card? For example 255.255.0.0 or 0.0.255.255?
