[Obi100]: StatusBacking Off (3s):TCP connection to 74.125.71.125 failed
The_Eggman:
Agreed. I shouldn't have to put it in the DMZ. I only did that for troubleshooting. I had it working fine with just the recommended port access behind the firewall. The DMZ should have removed many of the user-end network concerns. Something else seems to have changed. I thought of the same thing you did, but the other locations to which I have ready access also have an IPCop firewall. I will see what I can do. If I can't resolve, I will take you up on your offer.
The_Eggman:
You were right Steve. IPCop + Copfilter includes a robust proxy, antivirus, antispam, url filter, etc services. I had the OBi working behind it previously and I had rebooted the firewall probably a dozen times today, but I had never shut down the extra services while it was running because I thought the DMZ would bypass all that. I shut them all off at once because I was going to restart the services one by one to find the offender. As soon as I shut them off, the OBi started working again. I turned them all back on in an orderly fashion, but the OBi didn't disconnect. I'm not really sure what did it, but once I started them all again manually, the OBi kept working and I'm able to place calls again. Now to put it back behind the firewall and hope it still works. Thanks for the advice!
SteveInWA:
Great! I'm glad you got it working, even if the specific issue with the security system isn't clear yet. Thanks for the feedback.
The_Eggman:
Backs off when I put it behind the firewall. If I'm running a transparent proxy on port 8080, do I need to configure anything special in the OBi?
SteveInWA:
I don't have any experience trying to make Google Chat (XMPP) work through a proxy. I wouldn't be surprised if it failed, though.
It doesn't answer your question regarding proxy use, but here are the ports used by XMPP and by Hangouts:
