We are working on a municipal project here with an eFive 25 and 8 Cosy 131 VPN routers connected from around the town. Right now we are at the final testing/programming phase and we are all set up in our shop simulating as close to possible as the field. This is the first I have used an eFive but we probably have about 15 - 20 Cosy 131/141 units out in the field at this point so I am pretty familiar with them.
Yesterday I was working on completing my VPN setup from all the Cosy 131 units and my last one will not take my VPN configuration no mater what I try. I have used the same procedure on all previous 7 Cosy 131 units and they worked flawlessly. I pulled out a spare Cosy 131 unit that we need to provide as a spare and went through the same procedure using the same data as before with everything else in place (wiring & ethernet cable) and it worked flawlessly as well.
This is the procedure I have used to configure these:
- Update firmware to 13.1s0 and set IP using eBuddy.
- Log into the 131 and run the “System” wizard to change the eWon name and PW.
- Connect through FTP and upload the correct “comcfg.txt” for the eFive connection.
- Go back to the 131 and remove extra characters (¶) from the VPNCACert value uploaded in Setup > System > Storage > Edit COM cfg. (Not sure why this happens but I’ve had to do it for every 131 unit to make the connection work.)
- Enable 1:1 NAT over VPN for a PLC and an HMI in Setup > System > Communication > Routing.
- Reboot the Cosy 131 and it should connect - but this one doesn’t.
So with this problematic one on the summary page I have the following:
- Internet Connection > Internet status: Configuration is incomplete
- VPN Connection > Status: Configuration is incomplete
What is really strange is that I was receiving errors about the VPN in both the Event Logs and Realtime logs at one point but I can’t remember the language of those messages. Now however the only thing in both of my logs are this:
- System Booting, FWR: 13.1s0 (13.1), SN: --** [EF0000] (Event Log)
- USB port(s) powered on (Realtime Log)
That’s it. There is nothing else logged at all in this thing in either log under any category. All my other Cosy 131 units are logging all kinds of things.
I have done a few Level 2 resets to this Cosy 131 unit but I have not been able to get anywhere with this unit connecting to the eFive VPN. It will however connect just fine to the Talk2M VPN. I tested that configuration and was able to connect to it with eCatcher without a problem. I don’t know what to do with this unit at this point.
Any help or direction to look at would be appreciated.
