Question:
The Viewer cannot find the E3Server in a network protected by a firewall. E3’s port (6515) has already been released, but when trying to reconnect, the following message is displayed: “Server not found (PING fail)”. Do I have to release ICMP protocol (PING) for connection purposes?
Solution:
No, you don’t have to release ICMP protocol, only port 6515. The problem in this case is that the Viewer will run the PING command by default, via /NOPING option on the command line or via NOPING option on WebViewer’s page. You can force the Viewer/WebViewer to not depend on PING to try to connect to the server; this can be useful if PING (“echo” request from ICMP protocol) is blocked in the network and/or if there are frequent packet losses of this kind
Example:
"C:\Program Files (x86)\Elipse Software\Elipse E3\Bin\Viewer.exe" ServerName -noping
In case of the WebViewer, you must also add the following line in the ASP file (docwrite2.asp):
< param name="Ping" value="0" >
NOTE: we recommend that you grant access to ICMP protocol, because E3 uses this protocol in other types of connections too, such as HotStandby and Remote Domains, for example.
