The installer runs fine. I have the module turned on. I put in my user name and password, but when I click on the “SIGN IN” button I get this error “Error: A network error has occured while trying to sign in! Please check your network connectivity and try again.” This happens on two different machines. One is running windows 7 Pro 32 and the other is Server2008R2. I thought maybe my hardware firewall was blocking, so I bypassed it and now it works. I am running a Sonicwall TZ205. What do I need to do to operate behind the firewall. Thanks.
Hello @jwoolf
We can provide you with a document with all the connections and ports used by the Comodo One Module and it’s modules. Please send us an email to c1-support@comodo.com and we will provide this to you. Thank you.
Hello @jwoolf ,
The list of IP addresses and ports that need to be allowed in your firewall has been provided by email.
Here is what you provided for RMM:
| Other Components | FQDN | IP | Ports | Direction |
| RMM Agent & Console | --- | 69.4.80.244 69.4.89.244 69.4.82.59 69.4.80.249 | 8080, 443 TCP | Outgoing |
Well I tried everything including a rule for LAN>WAN Source:Any Destination: (My internal IP) Service: Any ALLOW
this did not work. I will try a packet capture to analyze the traffic to and from the RMM Administration Console.
I am using a Sonicwall TZ205
It was the Intrusion Prevention Service on the Sonicwall blocking comdo. I added the ip addresses to the IPS exclusion list now everything works. Thanks
