I have a problem with opera and my firewall (which is ESET Internet Security).

For personal reasons the firewall is set up to "interactive mode", which means each in- or outgoing connection from any Program or service is being monitored and user input is required in order to allow the connection.

The ESET firewall only allows absolute paths without wildcard support.
Since Opera changes its folder structure with each update, that means some extra work for me.
With every update I have to allow multiple applications to establish a connection.

And ESET is not planning to change anything (adding wildcard support).

The only thing I can do now is to add the Opera servers and allow any connection to them from any Program.

So in comes my question:

Does anyone know which servers (IP addresses, IP address ranges, etc.) are used by Opera (Opera Software AS)?
right now I have checked only a few IPs which were shown in the ESET dialog box:

For example the latest Opera Stable (v68) triggers following IP when Update & Recovery is chosen:
185.26.182.95
-> whois on whoer.net
-> IP address: 185.26.182.95
-> Hostname: ams.autoupdate.opera.com → 185.26.182.95
-> IP range: 185.26.182.0 - 185.26.183.50
-> ISP: Opera Mini Proxy
-> Organization: Opera Mini Proxy

Now I have set up a firewall rule to allow TCP&UDP in- and outbound connections to this IP range.

I hope this is safe enough...
Any other ideas? IP addresses? IP ranges? workarounds?

Many thanks in advance.
