RE: Server ports release for internet access for Sametime 3.0 b hausch 24.Sep.02 02:37 AM a Web browser Sametime Administration 3.0All Platforms
The ports for internet access depend on if you have enabled tunneling on port 80 or not.
If you enabled tunneling, opening port 80 on the external firewall would be enough. If not refer to the adminstration guide ... there will be a chapter discribing witch ports to be opened at the intenal and external firewall.
