How do I share files with users outside of my firewall with Office Communicator 2005?
Posted on 2007-11-30
I work for a company which has charged me the task of making Communicator 2005 our central chat and meeting client. Right now everything works well behind the firewall and I can even send files from outside of the firewall to myself, but when I try and send files from behind the firewall to outside of the firewall I receive the following error:
Cannot send "file.txt" to USER. This may be due to firewall restrictions or network problems. Please try again. If you need further assistance, contact your system administrator.
The system outside of the firewall receives the following error:
You cannot received the file "file.txt" from USER. This may be due to the firewall restrictions or network problems. If you need further assistance please contact your system administrator.
I have port 6891 open with the firewall software we use and we have 5060 and 5061 open on our Cisco PIX.
Any help would be greatly appreciated.
